Method Detail

createReference

public TopicMapReferenceIF createReference(java.net.URL url,
                                           java.lang.String id,

                                           LocatorIF base_address)

Specified by:

createReference in class AbstractOntopolyTopicMapSource

setFollowTopicRefs

public void setFollowTopicRefs(boolean followTopicRefs)

PUBLIC: If set to false topicRef elements pointing to external documents will not be traversed. The default is that the documents pointed to by those elements will be loaded (as per the XTM 1.0 specification).

Since:

EXPERIMENTAL: Sets the name of the external reference handler class. The specified class must have a default constructor.

getExternalReferenceHandlerClass

public java.lang.String getExternalReferenceHandlerClass()

EXPERIMENTAL: Gets the name of the external reference handler class.

getExternalReferenceHandler

public ExternalReferenceHandlerIF getExternalReferenceHandler()

PUBLIC: Gets the external reference handler. The reference handler will receive notifications on references to external topics and topic maps.

setValidation
