cvs commit: xml-xalan/java/src/org/apache/xalan/xsltc/dom SAXImpl.java
zongaro 2002/11/05 12:47:33
Modified: java/src/org/apache/xalan/xsltc/dom Tag: XSLTC_DTM
SAXImpl.java
Log:
1) Significant restructuring from Ilene Seelemann (ilene@ca.ibm.com) to
eliminate nested DOMBuilderImpl class. Now, SAXImpl itself implements the
DOMBuilder interface.
2) Changed characters(int, TransletOutputHandler) method to use the DTM's
dispatchCharactersEvents method. That method will emit characters events
for the string value of a node without creating String temporaries.
3) SAXImpl no longer implements Externalizable interface.
