Class XTMContentHandler

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      net.ontopia.topicmaps.xml.AbstractTopicMapContentHandler
          net.ontopia.topicmaps.xml.XTMContentHandler

All Implemented Interfaces:: ContentHandler, DTDHandler, EntityResolver, ErrorHandler, DeclHandler, LexicalHandler

public class XTMContentHandler
extends AbstractTopicMapContentHandler
implements LexicalHandler, DeclHandler
extends AbstractTopicMapContentHandler
implements LexicalHandler, DeclHandler

INTERNAL: SAX2 content handler used for importing XTM 1.0 topic map documents. The content handler builds a topic map object based on a SAX event stream conforming to the XTM topic map interchange syntax. See http://www.topicmaps.org/xtm/1.0/

Field Summary
`protected Map`	`entities` Keeps track of the declared entities, in order that the base URI can be set correctly in external entities.
`protected boolean`	`isSubDocument` Used to tell if we are reading the top-level XTM document (false) or if we are reading a merged-in XTM document (true).
`protected net.ontopia.topicmaps.xml.XTMContentHandler.LazyTopic`	`lazyTopic`
`static LocatorIF`	`nullPSI`
`protected ExternalReferenceHandlerIF`	`ref_handler`
`protected TopicMapStoreFactoryIF`	`stores`
`protected XMLReaderFactoryIF`	`xrfactory`
