Examples of SaxBuffer

org.apache.cocoon.pipeline.util.SaxBuffer
A class that can record SAX events and replay them later.
Use this class if you need to frequently generate smaller amounts of SAX events, or replay a set of recorded start events immediately.

Both {@link ContentHandler} and {@link LexicalHandler} are supported, the only exception is that thesetDocumentLocator event is not recorded.

org.apache.cocoon.xml.SaxBuffer
A class that can record SAX events and replay them later.
Compared to XMLByteStreamCompiler, this class is many times faster at sending out the recorded SAX events since it doesn't need to convert between byte and char representations etc. On the other hand, its data structure is more complex then a simple byte array, making XMLByteStreamCompiler better in case the recorded SAX should be stored long-term.
Use this class if you need to frequently generate smaller amounts of SAX events, or replay a set of recorded start events immediately.
