Method Detail

equals

public boolean equals(java.lang.Object other)

Node_ANY's are only equal to other Node_ANY's

Specified by:

equals in class Node

isConcrete

public boolean isConcrete()

Description copied from class: Node

Answer true iff this node is concrete, ie not variable, ie URI, blank, or literal.

Overrides:

isConcrete in class Node_Fluid

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

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
