From b1c93550a81a4fe1efdb21767913b52b2bf41d79 Mon Sep 17 00:00:00 2001 From: Glen Mazza Date: Mon, 19 Jul 2004 22:46:14 +0000 Subject: 1.) Moved exclusively to Simon's DefaultHandler object for both Transformer and SAXParser usage. DefaultHandler implements the ContentHandler interface so it can be used where the latter was previously used, also it provides more functionality. [1] 2.) Updated the examples and internal code accordingly. 3.) Renamed ExampleFO2PDFUsingSAX to ...Parser to avoid confusion (both use SAX.)
