RelayNode

public RelayNode(java.lang.String ID,
                 java.lang.String name)
Creates a new instance of RelayNode

Method Detail

accept

public void accept(edu.usc.alfa.xalfa.visitor.NodeVisitor v)
Description copied from class: Node
The visitor method to analyze xAlfa objects. This method is part of the Visitor pattern from GOF.

Specified by:
accept in class Node
Parameters:
v - Node Visitor that wants to visit this node.

toString

public java.lang.String toString()

toDebugString
