The area tree is conceptually defined in the - <a href="http://www.w3.org/TR/2001/REC-xsl-20011015/slice1.html#section-N742-Formatting">XSL-FO specification in chapter 1.1.2</a>. - The IF can be generated through the area tree XML Renderer (the XMLRenderer). - </p> - <p> - The intermediate format can be used to generate intermediate documents that are modified - before they are finally rendered to their ultimate output format. Modifications include - adjusting and changing trait values, adding or modifying area objects, inserting prefabricated - pages, overlays, imposition (n-up, rotation, scaling etc.). Multiple IF files can be combined - to a single output file. - </p> - </section> - <section id="usage"> - <title>Usage of the Intermediate Format</title> - <p> - As already mentioned, the IF is generated by using the <strong>XMLRenderer</strong> (MIME type: - <strong>application/X-fop-areatree</strong>). So, you basically set the right MIME type for - the output format and process your FO files as if you would create a PDF file. However, there - is an important detail to consider: The various Renderers don't all use the same font sources. - To be able to create the right area tree for the ultimate output file, you need to create - the IF file using the right font setup. This is achieved by telling the XMLRenderer to mimic - another renderer. This is done by calling the XMLRenderer's mimicRenderer() method with an - instance of the ultimate target renderer as the single parameter. This has a consequence: An - IF file rendered with the Java2DRenderer may not look as expected when it was actually generated - for the PDF renderer. For renderers that use the same font setup, this restriction does not - apply (PDF and PS, for example). Generating the intermediate format file is the first step. - </p> - <p> - The second step is to reparse the IF file using the <strong>AreaTreeParser</strong> which is - found in the org.apache.fop.area package. The pages retrieved from the IF file are added to an - AreaTreeModel instance from where they are normally rendered using one of the available Renderer - implementations. You can find examples for the IF processing in the - <a href="http://svn.apache.org/viewcvs.cgi/xmlgraphics/fop/trunk/examples/embedding/java/embedding/intermediate/"><code>examples/embedding</code></a> - directory in the FOP distribution - </p> - <p> - The basic pattern to parse the IF format looks like this: - </p> - <source><![CDATA[ -FopFactory fopFactory = FopFactory.newInstance(); - -// Setup output -OutputStream out = new java.io.FileOutputStream(pdffile); -out = new java.io.BufferedOutputStream(out); -try { - //Setup fonts and user agent - FontInfo fontInfo = new FontInfo(); - FOUserAgent userAgent = fopFactory.newFOUserAgent(); - - //Construct the AreaTreeModel that will received the individual pages - AreaTreeModel treeModel = new RenderPagesModel(userAgent, - MimeConstants.MIME_PDF, fontInfo, out); - - //Parse the IF file into the area tree - AreaTreeParser parser = new AreaTreeParser(); - Source src = new StreamSource(myIFFile); - parser.parse(src, treeModel, userAgent); - - //Signal the end of the processing. The renderer can finalize the target document. - treeModel.endDocument(); -} finally { - out.close(); -}]]></source> - <p> - This example simply reads an IF file and renders it to a PDF file. Please note, that in normal - FOP operation you're shielded from having to instantiate the FontInfo object yourself. This - is normally a task of the AreaTreeHandler which is not present in this scenario. The same - applies to the AreaTreeModel instance, in this case an instance of a subclass called - RenderPagesModel. RenderPagesModel is ideal in this case as it has very little overhead - processing the individual pages. An important line in the example is the call to - <code>endDocument()</code> on the AreaTreeModel. This lets the Renderer know that the processing - is now finished. - </p> - <p> - The intermediate format can also be used from the <a href="running.html#standalone-start">command-line</a> - by using the "-atin" parameter for specifying the area tree XML as input file. You can also - specify a "mimic renderer" by inserting a MIME type between "-at" and the output file. - </p> - <section id="concat"> - <title>Concatenating Documents</title> - <p> - This initial example is obviously not very useful. It would be faster to create the PDF file - directly. As the <a href="http://svn.apache.org/repos/asf/xmlgraphics/fop/trunk/examples/embedding/java/embedding/intermediate/ExampleConcat.java">ExampleConcat.java</a> - example shows you can easily parse multiple IF files in a row and add the parsed pages to the - same AreaTreeModel instance which essentially concatenates all the input document to one single - output document. - </p> - </section> - <section id="modifying"> - <title>Modifying Documents</title> - <p> - One of the most important use cases for the intermediate format is obviously modifying the area - tree XML before finally rendering it to the target format. You can easily use XSLT to process - the IF file according to your needs. Please note, that we will currently not formally describe - the intermediate format. You need to have a good understanding its structure so you don't - create any non-parseable files. We may add an XML Schema and more detailed documentation at a - later time. You're invited to help us with that. - </p> - </section> - <section id="advanced"> - <title>Advanced Use</title> - <p> - The generation of the intermediate format as well as it parsing process has been designed to allow - for maximum flexibility and optimization. Please note that you can call <code>setTransformerHandler()</code> on - XMLRenderer to give the XMLRenderer your own TransformerHandler instance in case you would like to - do custom serialization (to a W3C DOM, for example) and/or to directly modify the area tree using - XSLT.

Here's a code example: + </p> + <source><![CDATA[Event ev = new Event(this, "complain", EventSeverity.WARN, + Event.paramsBuilder() + .param("reason", "I'm tired") + .param("blah", new Integer(23)) + .build()); +EventBroadcaster broadcaster = [get it from somewhere]; +broadcaster.broadcastEvent(ev); +]]></source> + <p> + The <code>Event.paramsBuilder()</code> is a + <a href="http://en.wikipedia.org/wiki/Fluent_interface">fluent interface</a> + to help with the build-up of the parameters. You could just as well instantiate a + <code>Map</code> (<code>Map<String, Object></code>) and fill it with values. + </p> + </section> + <section id="event-producer"> + <title>The EventProducer interface</title> + <p> + To simplify event production, the event subsystem provides the <code>EventProducer</code> + interface. You can create interfaces which extend <code>EventProducer</code>. These + interfaces will contain one method per event to be generated. By contract, each event + method must have as its first parameter a parameter named "source" (Type Object) which + indicates the object that generated the event. After that come an arbitrary number of + parameters of any type as needed by the event. + </p> + <p> + The event producer interface does not need to have any implementation. The implementation + is produced at runtime by a dynamic proxy created by <code>DefaultEventBroadcaster</code>. + The dynamic proxy creates <code>Event</code> instances for each method call against + the event producer interface. Each parameter (except "source") is added to the event's + parameter map. + </p> + <p> + To simplify the code needed to get an instance of the event producer interface it is + suggested to create a public inner provider class inside the interface. + </p> + <p> + Here's an example of such an event producer interface: + </p> + <source><![CDATA[public interface MyEventProducer extends EventProducer { + + public class Provider { + + public static MyEventProducer get(EventBroadcaster broadcaster) { + return (MyEventProducer)broadcaster.getEventProducerFor(MyEventProducer.class); + } + } + + /** + * Complain about something. + * @param source the event source + * @param reason the reason for the complaint + * @param blah the complaint + * @event.severity WARN + */ + void complain(Object source, String reason, int blah); + +}]]></source> + <p> + To produce the same event as in the first example above, you'd use the following code: + </p> + <source><![CDATA[EventBroadcaster broadcaster = [get it from somewhere]; +TestEventProducer producer = TestEventProducer.Provider.get(broadcaster); +producer.complain(this, "I'm tired", 23);]]></source> + </section> + <section id="event-model"> + <title>The event model</title> + <p> + Inside an invocation handler for a dynamic proxy, there's no information about + the names of each parameter. The JVM doesn't provide it. The only thing you know is + the interface and method name. In order to properly fill the <code>Event</code>'s + parameter map we need to know the parameter names. These are retrieved from an + event object model. This is found in the <code>org.apache.fop.events.model</code> + package. The data for the object model is retrieved from an XML representation of the + event model that is loaded as a resource. The XML representation is generated using an + Ant task at build time (<code>ant resourcegen</code>). The Ant task (found in + <code>src/codegen/java/org/apache/fop/tools/EventProducerCollectorTask.java</code>) + scans FOP's sources for descendants of the <code>EventProducer</code> interface and + uses <a href="http://qdox.codehaus.org/">QDox</a> to parse these interfaces. + </p> + <p> + The event model XML files are generated during build by the Ant task mentioned above when + running the "resourcegen" task. So just run <code>"ant resourcegen"</code> if you receive + a <code>MissingResourceException</code> at runtime indicating that + <code>"event-model.xml"</code> is missing. + </p> + <p> + Primarily, the QDox-based collector task records the parameters' names and types. + Furthermore, it extracts additional attributes embedded as Javadoc comments from + the methods. At the moment, the only such attribute is "@event.severity" which indicates + the default event severity (which can be changed by event listeners). The example event + producer above shows the Javadocs for an event method. + </p> + <p> + There's one more information that is extracted from the event producer information for + the event model: an optional primary exception. The first exception in the "throws" + declaration of an event method is noted. It is used to throw an exception from + the invocation handler if the event has an event severity of "FATAL" when all + listeners have been called (listeners can update the event severity). Please note + that an implementation of + <code>org.apache.fop.events.EventExceptionManager$ExceptionFactory</code> has to be + registered for the <code>EventExceptionManager</code> to be able to construct the + exception from an event. + </p> + <p> + For a given application, there can be multiple event models active at the same time. + In FOP, each renderer is considered to be a plug-in and provides its own specific + event model. The individual event models are provided through an + <code>EventModelFactory</code>. This interface is implemented for each event model + and registered through the service provider mechanism + (see the <a href="#plug-ins">plug-ins section</a> for details). + </p> + </section> + <section id="event-severity"> + <title>Event severity</title> + <p> + Four different levels of severity for events has been defined: + </p> + <ol> + <li>INFO: informational only</li> + <li>WARN: a Warning</li> + <li>ERROR: an error condition from which FOP can recover. FOP will continue processing.</li> + <li>FATAL: a fatal error which causes an exception in the end and FOP will stop processing.</li> + </ol> + <p> + Event listeners can choose to ignore certain events based on their event severity. + Please note that you may recieve an event "twice" in a specific case: if there is + a fatal error an event is generated and sent to the listeners. After that an exception + is thrown with the same information and processing stops. If the fatal event is + shown to the user and the following exception is equally presented to the user it + may appear that the event is duplicated. Of course, the same information is just + published through two different channels. + </p> + </section> + <section id="plug-ins"> + <title>Plug-ins to the event subsystem</title> + <p> + The event subsystem is extensible. There are a number of extension points: + </p> + <ul> + <li> + <strong><code>org.apache.fop.events.model.EventModelFactory</code>:</strong> Provides + an event model to the event subsystem. + </li> + <li> + <strong><code>org.apache.fop.events.EventExceptionManager$ExceptionFactory</code>:</strong> + Creates exceptions for events, i.e. turns an event into a specific exception. + </li> + </ul> + <p> + The names in bold above are used as filenames for the service provider files that + are placed in the <code>META-INF/services</code> directory. That way, they are + automatically detected. This is a mechanism defined by the + <a href="http://java.sun.com/j2se/1.4.2/docs/guide/jar/jar.html#Service%20Provider">JAR file specification</a>. + </p> + </section> + <section id="l10n"> + <title>Localization (L10n)</title> + <p> + One goal of the event subsystem was to have localized (translated) event messages. + The <code>EventFormatter</code> class can be used to convert an event to a + human-readable message. Each <code>EventProducer</code> can provide its own XML-based + translation file. If there is none, a central translation file is used, called + "EventFormatter.xml" (found in the same directory as the <code>EventFormatter</code> + class). + </p> + <p> + The XML format used by the <code>EventFormatter</code> is the same as + <a href="ext:cocoon">Apache Cocoon's</a> catalog format. Here's an example: + </p> + <source><![CDATA[<?xml version="1.0" encoding="UTF-8"?> +<catalogue xml:lang="en"> + <message key="locator"> + [ (See position {loc})| (See {#gatherContextInfo})| (No context info available)] + </message> + <message key="org.apache.fop.render.rtf.RTFEventProducer.explicitTableColumnsRequired"> + RTF output requires that all table-columns for a table are defined.

The class used to do variable replacement in the templates is + <code>org.apache.fop.util.text.AdvancedMessageFormat</code> which is more powerful + than the <code>MessageFormat</code> classes provided by the Java class library + (<code>java.util.text</code> package). + </p> + <p> + "locator" is a template that is reused by the other message templates + by referencing it through "{{locator}}". This is some kind of include command. + </p> + <p> + Normal event parameters are accessed by name inside single curly braces, for example: + "{node}". For objects, this format just uses the <code>toString()</code> method to turn + the object into a string, unless there is an <code>ObjectFormatter</code> registered + for that type (there's an example for <code>org.xml.sax.Locator</code>). + </p> + <p> + The single curly braces pattern supports additional features. For example, it is possible + to do this: "{start,if,start,end}". "if" here is a special field modifier that evaluates + "start" as a boolean and if that is true returns the text right after the second comma + ("start"). Otherwise it returns the text after the third comma ("end"). The "equals" + modifier is similar to "if" but it takes as an additional (comma-separated) parameter + right after the "equals" modifier, a string that is compared to the value of the variable. + An example: {severity,equals,EventSeverity:FATAL,,some text} (this adds "some text" if + the severity is not FATAL). + </p> + <p> + Additional such modifiers can be added by implementing the + <code>AdvancedMessageFormat$Part</code> and <code>AdvancedMessageFormat$PartFactory</code> + interfaces. + </p> + <p> + Square braces can be used to specify optional template sections. The whole section will + be omitted if any of the variables used within are unavailable. Pipe (|) characters can + be used to specify alternative sub-templates (see "locator" above for an example). + </p> + <p> + Developers can also register a function (in the above example: + <code>{#gatherContextInfo})</code> + to do more complex information rendering. These functions are implementations of the + <code>AdvancedMessageFormat$Function</code> interface. Please take care that this is + done in a locale-independent way as there is no locale information available, yet. + </p> + </section> + </section> + </body> +</document> diff --git a/src/documentation/content/xdocs/1.0/extensions.xml b/src/documentation/content/xdocs/1.0/extensions.xml new file mode 100644 index 000000000..107f6c5b3 --- /dev/null +++ b/src/documentation/content/xdocs/1.0/extensions.xml @@ -0,0 +1,340 @@ +<?xml version="1.0" standalone="no"?> +<!-- + Licensed to the Apache Software Foundation (ASF) under one or more + contributor license agreements.

The first one + (let's call it the area tree XML format) is basically a 1:1 XML representation of FOP's + area tree as generated by the layout engine. The area tree is conceptually defined in the + <a href="http://www.w3.org/TR/2001/REC-xsl-20011015/slice1.html#section-N742-Formatting">XSL-FO specification in chapter 1.1.2</a>. + Even though the area tree is mentioned in the XSL-FO specification, this part is not + standardized. Therefore, the area tree XML format is a FOP-proprietary XML file format. + The area tree XML can be generated through the area tree XML Renderer (the XMLRenderer). + </p> + <p> + The second intermediate format (which we shall name exactly like this: the intermediate + format) + is a recent addition which tries to meet a slightly different set of goals. It is highly + optimized for speed. + </p> + <p> + The intermediate format can be used to generate intermediate documents that are modified + before they are finally rendered to their ultimate output format. Modifications include + adjusting and changing trait values, adding or modifying area objects, inserting prefabricated + pages, overlays, imposition (n-up, rotation, scaling etc.). Multiple IF files can be combined + to a single output file. + </p> + </section> + <section id="which-if"> + <title>Which Intermediate Format to choose?</title> + <p> + Both formats have their use cases, so the choice you will make will depend on your + particular situation. Here is a list of strengths and use cases for both formats: + </p> + <section id="strengths-at"> + <title>Area Tree XML (AT XML)</title> + <ul> + <li>1:1 representation of FOP's area tree in XML.</li> + <li>Contains more structure information than the new intermediate format.</li> + <li>Used in FOP's layout engine test suite for regression testing.</li> + </ul> + </section> + <section id="strengths-if"> + <title>Intermediate Format (IF)</title> + <ul> + <li>Highly optimized for speed.</li> + <li>Smaller XML files.</li> + <li>Easier to post-process.</li> + <li>XML Schema is available.</li> + <li> + Recommended for use cases where documents are formatted concurrently and later + concatenated to a single print job. + </li> + </ul> + </section> + <p> + More technical information about the two formats can be found on the + <a href="http://wiki.apache.org/xmlgraphics-fop/AreaTreeIntermediateXml/NewDesign">FOP Wiki</a>. + </p> + </section> + <section id="architecture"> + <title>Architectural Overview</title> + <figure src="images/if-architecture-overview.png" + alt="Diagram with an architectural overview over the intermediate formats"/> + </section> + <section id="usage"> + <title>Usage of the Area Tree XML format (AT XML)</title> + <p> + As already mentioned, the area tree XML format is generated by using the + <strong>XMLRenderer</strong> (MIME type: <strong>application/X-fop-areatree</strong>). + So, you basically set the right MIME type for the output format and process your FO files + as if you would create a PDF file. + </p> + <p> + However, there is an important detail to consider: The + various Renderers don't all use the same font sources. To be able to create the right + area tree for the ultimate output format, you need to create the area tree XML file using + the right font setup. This is achieved by telling the XMLRenderer to mimic another + renderer. This is done by calling the XMLRenderer's mimicRenderer() method with an + instance of the ultimate target renderer as the single parameter. This has a consequence: + An area tree XML file rendered with the Java2DRenderer may not look as expected when it + was actually generated for the PDF renderer. For renderers that use the same font setup, + this restriction does not apply (PDF and PS, for example). Generating the area tree XML + format file is the first step. + </p> + <p> + The second step is to reparse the file using the <strong>AreaTreeParser</strong> which is + found in the org.apache.fop.area package. The pages retrieved from the area tree XML file + are added to an AreaTreeModel instance from where they are normally rendered using one of + the available Renderer implementations. You can find examples for the area tree XML + processing in the + <a href="http://svn.apache.org/viewvc/xmlgraphics/fop/trunk/examples/embedding/java/embedding/intermediate/"><code>examples/embedding</code></a> + directory in the FOP distribution. + </p> + <p> + The basic pattern to parse the area tree XML format looks like this: + </p> + <source><![CDATA[ +FopFactory fopFactory = FopFactory.newInstance(); + +// Setup output +OutputStream out = new java.io.FileOutputStream(pdffile); +out = new java.io.BufferedOutputStream(out); +try { + //Setup fonts and user agent + FontInfo fontInfo = new FontInfo(); + FOUserAgent userAgent = fopFactory.newFOUserAgent(); + + //Construct the AreaTreeModel that will received the individual pages + AreaTreeModel treeModel = new RenderPagesModel(userAgent, + MimeConstants.MIME_PDF, fontInfo, out); + + //Parse the area tree file into the area tree + AreaTreeParser parser = new AreaTreeParser(); + Source src = new StreamSource(myIFFile); + parser.parse(src, treeModel, userAgent); + + //Signal the end of the processing. The renderer can finalize the target document. + treeModel.endDocument(); +} finally { + out.close(); +}]]></source> + <p> + This example simply reads an area tree file and renders it to a PDF file. Please note, that in normal + FOP operation you're shielded from having to instantiate the FontInfo object yourself. This + is normally a task of the AreaTreeHandler which is not present in this scenario. The same + applies to the AreaTreeModel instance, in this case an instance of a subclass called + RenderPagesModel. RenderPagesModel is ideal in this case as it has very little overhead + processing the individual pages. An important line in the example is the call to + <code>endDocument()</code> on the AreaTreeModel. This lets the Renderer know that the processing + is now finished. + </p> + <p> + The area tree XML format can also be used from the <a href="running.html#standalone-start">command-line</a> + by using the "-atin" parameter for specifying the area tree XML as input file.

To be able + to create the right IF for the ultimate output file, you need to create the IF file using + the right font setup. This is achieved by telling the IFRenderer (responsible for + converting the area tree into calls to the IFDocumentHandler and IFPainter interfaces) + to mimic another renderer. This is done by calling the IFSerializer's + mimicDocumentHandler() method with an instance of the ultimate target document handler + as the single parameter.

For implementations that use the same font setup, + this restriction does not apply (PDF and PS, for example). Generating the Intermediate + Format file is the first step. + </p> + <p> + The second step is to reparse the file using the <strong>IFParser</strong> which is + found in the org.apache.fop.render.intermediate package. The IFParser simply takes an + IFDocumentHandler instance against which it generates the appropriate calls.
