Method Detail

equals

Deprecated.

Node_NULL's are equal to no null nodes; strictly speaking, this incorrect but suits our purposes. really want an isNull method on Node but that's too much surgery.

Specified by:

equals in class Node

visitWith

public Object visitWith(NodeVisitor v)

Deprecated.

Description copied from class: Node

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

Specified by:

Parameters:

v - the visitor to apply to the node

Returns:

the value returned by the applied method
