URI	getURI() The URI identifiying this resource.
int	hashCode() Returns a hash-code value for this BlankNode.
boolean	isURIReference() Returns true if this is a URIReference, otherwise it's a BlankNode.

Method Detail

isURIReference

public boolean isURIReference()

Description copied from interface: Resource

Returns true if this is a URIReference, otherwise it's a BlankNode.

Specified by:

isURIReference in interface Resource

Returns:

true if this is a URIReference, otherwise it's a BlankNode.

getUnderlyingNode

public Node getUnderlyingNode()

Description copied from interface: Resource

Returns the node that the resource represents - either a BlankNode or a URIReference.

Specified by:

getUnderlyingNode in interface Resource

Returns:

the BlankNode or URIReference.

getURI

public URI getURI()

Description copied from interface: URIReference

The URI identifiying this resource.

Specified by:

getURI in interface URIReference

Returns:

the URI identifying this resource.

hashCode

public int hashCode()

Description copied from interface: BlankNode

Returns a hash-code value for this BlankNode. While the implementation is not defined, if there is a blank node identifier then it should be the hash code generated from this. Hash code generation should follow the normal contract.

Specified by:

hashCode in interface BlankNode

Specified by:

hashCode in interface URIReference

Overrides:

hashCode in class Object

Returns:

a hash-code value for this blank node.

equals

public boolean equals(Object obj)

Description copied from interface: BlankNode

While the internal structure of a BlankNode is not defined equality between two nodes should be able to be determined. In some representations this equality would be defined by a blank node identifier.

Specified by:

equals in interface BlankNode

Specified by:

equals in interface URIReference

Overrides:

equals in class Object

Parameters:

obj - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

accept

public void accept(TypedNodeVisitor visitor)

Description copied from interface: TypedNodeVisitable

Accept a call from a TypedNodeVisitor.

Specified by:

accept in interface TypedNodeVisitable

Parameters:

visitor - the object doing the visiting.

toString

public String toString()

Overrides:

toString in class Object

getUID

public String getUID()

Description copied from interface: GlobalizedBlankNode

Returns the identifier for the blank node.

Specified by:

getUID in interface GlobalizedBlankNode

Returns:

the identifier for the blank node.
