True if this resource does not have an associated URI.

Specified by:

isAnonymous in interface AResource

Returns:

True if this resource is anonymous.

getAnonymousID

public String getAnonymousID()

Description copied from interface: AResource

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

Specified by:

getAnonymousID in interface AResource

Returns:

An identifier with file scope for this anonymous resource..

getURI

public String getURI()

Description copied from interface: AResource

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

Specified by:

getURI in interface AResource

Returns:

The URI reference of this resource.

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

getUserData

public Object getUserData()

Description copied from interface: AResource

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.

Specified by:

getUserData in interface AResource

Returns:

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

setUserData

public void setUserData(Object d)

Description copied from interface: AResource

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.

Specified by:

setUserData in interface AResource

Parameters:

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

hasNodeID

public boolean hasNodeID()

Description copied from interface: AResource

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

Specified by:

hasNodeID in interface AResource

Returns:

true if this resource has a nodeID

setHasBeenUsed

public void setHasBeenUsed()

Description copied from interface: AResourceInternal

Only for blank nodes - non blank need not support.

Specified by:

setHasBeenUsed in interface AResourceInternal
