From: Peter Bernard West Date: Sat, 28 Feb 2004 02:06:44 +0000 (+0000) Subject: Added page-sequence and generated-by args to Area constructor. X-Git-Tag: Alt-Design_pre_awt_renderer_import~26 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=ac2c1eac8dc8cc3ed3347d63bc97c974a705b4fe;p=xmlgraphics-fop.git Added page-sequence and generated-by args to Area constructor. Modified Viewport and ReferenceArea classes to handle appropriate functions. Constructor modifications to match superclasses. Some synchronization of unsynchronized methods. git-svn-id: https://svn.apache.org/repos/asf/xmlgraphics/fop/branches/FOP_0-20-0_Alt-Design@197396 13f79535-47bb-0310-9956-ffa450edef68 --- diff --git a/src/java/org/apache/fop/area/AbstractReferenceArea.java b/src/java/org/apache/fop/area/AbstractReferenceArea.java index f20cdf403..fa3c995cc 100644 --- a/src/java/org/apache/fop/area/AbstractReferenceArea.java +++ b/src/java/org/apache/fop/area/AbstractReferenceArea.java @@ -19,6 +19,8 @@ package org.apache.fop.area; import org.apache.fop.datastructs.Node; +import org.apache.fop.fo.FONode; +import org.apache.fop.fo.flow.FoPageSequence; /** * @author pbw @@ -32,25 +34,17 @@ public abstract class AbstractReferenceArea protected CoordTransformer transformer = new CoordTransformer(); /** - * @param parent - * @param index - * @param areaSync - * @throws IndexOutOfBoundsException + * @param pageSeq through which this area was generated + * @param generatedBy the given FONode generated this + * @param parent area of this + * @param sync object on which operations in this are synchronized */ - public AbstractReferenceArea(Node parent, int index, Object areaSync) - throws IndexOutOfBoundsException { - super(parent, index, areaSync); - // TODO Auto-generated constructor stub - } - - /** - * @param parent - * @param areaSync - * @throws IndexOutOfBoundsException - */ - public AbstractReferenceArea(Node parent, Object areaSync) - throws IndexOutOfBoundsException { - super(parent, areaSync); + public AbstractReferenceArea( + FoPageSequence pageSeq, + FONode generatedBy, + Node parent, + Object sync) { + super(pageSeq, generatedBy, parent, sync); // TODO Auto-generated constructor stub } @@ -64,7 +58,9 @@ public abstract class AbstractReferenceArea * @param transformer to position this reference area */ public void setCoordTransformer(CoordTransformer transformer) { - this.transformer = transformer; + synchronized (sync) { + this.transformer = transformer; + } } /** @@ -73,7 +69,9 @@ public abstract class AbstractReferenceArea * @return the current transformer to position this reference area */ public CoordTransformer getCoordTransformer() { - return this.transformer; + synchronized (sync) { + return this.transformer; + } } /** diff --git a/src/java/org/apache/fop/area/AbstractViewport.java b/src/java/org/apache/fop/area/AbstractViewport.java new file mode 100644 index 000000000..4bfc194de --- /dev/null +++ b/src/java/org/apache/fop/area/AbstractViewport.java @@ -0,0 +1,139 @@ +/* + * + * Copyright 2004 The Apache Software Foundation. + * + * Licensed under the Apache License, Version 2.0 (the "License"); + * you may not use this file except in compliance with the License. + * You may obtain a copy of the License at + * + * http://www.apache.org/licenses/LICENSE-2.0 + * + * Unless required by applicable law or agreed to in writing, software + * distributed under the License is distributed on an "AS IS" BASIS, + * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + * See the License for the specific language governing permissions and + * limitations under the License. + * + * Created on 27/02/2004 + * $Id$ + */ +package org.apache.fop.area; + +import java.awt.geom.Rectangle2D; + +import org.apache.fop.datastructs.Node; +import org.apache.fop.fo.FONode; +import org.apache.fop.fo.flow.FoPageSequence; + +/** + * @author pbw + * @version $Revision$ $Name$ + */ +public class AbstractViewport +extends Area +implements Viewport { + + /** The viewport rectange */ + protected Rectangle2D viewArea = null; + + /** Does the viewport rectange clip the reference-area?
