All Implemented Interfaces:

Serializable

public class Node_ANY
extends Node_Fluid

Method Summary

Modifier and Type	Method and Description
boolean	equals(Object other) Node_ANY's are only equal to other Node_ANY's
boolean	matches(Node other) Answer true iff this node accepts the other one as a match.
String	toString() Answer a human-readable representation of this Node.
String	toString(PrefixMapping pm, boolean quoting) Answer a human readable representation of this Node, quoting literals if specified, and compressing URIs using the prefix mapping supplied.
Object	visitWith(NodeVisitor v) Visit a Node and dispatch on it to the appropriate method from the NodeVisitor v.

Method Detail

equals

public boolean equals(Object other)

Node_ANY's are only equal to other Node_ANY's

Specified by:

equals in class Node

visitWith

public 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

matches

public boolean matches(Node other)

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:

other - a node to test for matching

Returns:

true iff this node accepts the other as a match

toString

public String toString()

Description copied from class: Node

Answer a human-readable representation of this Node. It will not compress URIs, nor quote literals (because at the moment too many places use toString() for something machine-oriented).

Overrides:

toString in class Node

toString

public String toString(PrefixMapping pm,
                       boolean quoting)

Description copied from class: Node

Answer a human readable representation of this Node, quoting literals if specified, and compressing URIs using the prefix mapping supplied.

Overrides:

toString in class Node
