Interface IncrementalSAXSource
- All Known Implementing Classes:
IncrementalSAXSource_Filter
,IncrementalSAXSource_Xerces
public interface IncrementalSAXSource
IncrementalSAXSource is an API that delivers a small number of SAX events each time a request is made from a "controller" coroutine. See IncrementalSAXFilter and IncrementalSAXFilter_Xerces for examples. Note that interaction is via the deliverMoreNodes method, and therefore coroutine support is not exposed here.

Method Summary
Modifier and TypeMethodDescriptiondeliverMoreNodes
(boolean parsemore) deliverMoreNodes() is a simple API which tells the thread in which the IncrementalSAXSource is running to deliver more events (true), or stop delivering events and close out its input (false).void
setContentHandler
(ContentHandler handler) Register a SAX-style content handler for us to output tovoid
setDTDHandler
(DTDHandler handler) Register a SAX-style DTD handler for us to output tovoid
setLexicalHandler
(LexicalHandler handler) Register a SAX-style lexical handler for us to output tovoid
startParse
(InputSource source) Launch an XMLReader's parsing operation, feeding events to this IncrementalSAXSource.

deliverMoreNodes
deliverMoreNodes() is a simple API which tells the thread in which the IncrementalSAXSource is running to deliver more events (true), or stop delivering events and close out its input (false). This is intended to be called from one of our partner coroutines, and serves to encapsulate the coroutine communication protocol.- Parameters:
parsemore
- If true, tells the incremental SAX stream to deliver another chunk of events. If false, finishes out the stream.- Returns:
- Boolean.TRUE if the IncrementalSAXSource believes more data may be available for further parsing. Boolean.FALSE if parsing ran to completion, or was ended by deliverMoreNodes(false).
-
startParse
Launch an XMLReader's parsing operation, feeding events to this IncrementalSAXSource. In some implementations, this may launch a thread which runs the previously supplied XMLReader's parse() operation. In others, it may do other forms of initialization.- Throws:
SAXException
- is parse thread is already in progress or parsing can not be started.
