public RDFLiteral(@Nonnull
                  OWLLiteral literal)

Parameters:

literal - the wrapped literal

Method Detail

isLiteral

public boolean isLiteral()

Description copied from class: RDFNode

Determines if this node is a literal node.

Specified by:

isLiteral in class RDFNode

Returns:

true if this node is a literal, otherwise false.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

toString in class Object

getIRI

public IRI getIRI()

Description copied from interface: HasIRI

Gets the IRI of this object

Returns:

The IRI of this object

isAnonymous

public boolean isAnonymous()

Description copied from class: RDFNode

Determines if this node is a resource and is anonymous.

Specified by:

isAnonymous in class RDFNode

Returns:

true if this is a resource node (i.e. isLiteral returns false) and the node is anonymous, or false if this is a resource node and is not anonymous.
