Method Summary

String	getAnonymousID() A string distinguishing this anonymous resource, from other anonymous resources.
String	getURI() The URI reference for this resource, if any.
Object	getUserData() The user data allows the RDF application to store one Object with each blank node during parsing.
boolean	hasNodeID() True, if this is an anonymous resource with an explicit rdf:nodeID.
boolean	isAnonymous() True if this resource does not have an associated URI.
void	setUserData(Object d) The user data allows the RDF application to store one Object with each blank node during parsing.

Method Detail

getAnonymousID

String getAnonymousID()

A string distinguishing this anonymous resource, from other anonymous resources. Undefined if isAnonymous() returns false.

Returns:

An identifier with file scope for this anonymous resource..

getURI

String getURI()

The URI reference for this resource, if any. Not defined if isAnonymous() returns true.

Returns:

The URI reference of this resource.

getUserData

Object getUserData()

The user data allows the RDF application to store one Object with each blank node during parsing. This may help with garbage collect strategies when parsing huge files. No references to the user data are maintained after a blank node goes out of scope.

Returns:

A user data object previously stored with setUserData(java.lang.Object); or null if none.

hasNodeID

boolean hasNodeID()

True, if this is an anonymous resource with an explicit rdf:nodeID.

Returns:

true if this resource has a nodeID

isAnonymous

boolean isAnonymous()

True if this resource does not have an associated URI.

Returns:

True if this resource is anonymous.

setUserData

void setUserData(Object d)

The user data allows the RDF application to store one Object with each blank node during parsing. This may help with garbage collect strategies when parsing huge files. No references to the user data are maintained after a blank node goes out of scope.

See note about large files in class documentation for ARP.

Parameters:

d - A user data object which may be retrieved later with getUserData().
