DefaultTopicMapSource(TopicMapReferenceIF reference)

Method Summary

void	addReference(TopicMapReferenceIF reference) INTERNAL: Adds the reference to the source and registers the source as the source of the reference.
TopicMapReferenceIF	createTopicMap(java.lang.String name, java.lang.String baseAddress) PUBLIC: Creates a new topic map in the underlying source and returns a reference to the created topic map.
boolean	getHidden()
java.lang.String	getId() PUBLIC: Gets the id of the source.
