public Node_Literal(java.lang.Object label)

Method Detail

getLiteral

public com.hp.hpl.jena.graph.impl.LiteralLabel getLiteral()

Description copied from class: Node

get the literal value of a literal node, otherwise die horribly

Overrides:

getLiteral in class Node

isLiteral

public boolean isLiteral()

Description copied from class: Node

is this a literal node - overridden in Node_Literal

Overrides:

isLiteral in class Node

visitWith

public java.lang.Object visitWith(NodeVisitor v)

Description copied from class: Node

Visit a Node and dispatch on it to the appropriate method from the NodeVisitor v.

Specified by:

visitWith in class Node

Parameters:

v - the visitor to apply to the node

Returns:

the value returned by the applied method

equals

public boolean equals(java.lang.Object other)

Description copied from class: Node

Nodes only equal other Nodes that have equal labels.

Specified by:

equals in class Node

sameValueAs

public boolean sameValueAs(java.lang.Object o)

Test that two nodes are semantically equivalent. In some cases this may be the sames as equals, in others equals is stricter. For example, two xsd:int literals with the same value but different language tag are semantically equivalent but distinguished by the java equality function in order to support round tripping.

Default implementation is to use equals, subclasses should override this.

Overrides:

sameValueAs in class Node

matches

public boolean matches(Node x)

Description copied from class: Node

Answer true iff this node accepts the other one as a match. The default is an equality test; it is over-ridden in subclasses to provide the appropriate semantics for literals, ANY, and variables.

Overrides:

matches in class Node

Parameters:

x - a node to test for matching

Returns:

true iff this node accepts the other as a match
