      ptolemy.data.expr.ASTPtProductNode

All Implemented Interfaces:

java.lang.Cloneable, Node

public class ASTPtProductNode
extends ASTPtRootNode

The parse tree created from the expression string consists of a hierarchy of node objects. This class represents product(*,/,%) nodes in the parse tree.

Constructor Detail

public ASTPtProductNode(int id)

ASTPtProductNode

public ASTPtProductNode(PtParser p,
                        int id)

Method Detail

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Clone the parse tree node by invoking the clone() method of the base class. The new node copies the list of operators (*, /) represented by this node.

Overrides:

clone in class ASTPtRootNode

Returns:

A new parse tree node.

Throws:

java.lang.CloneNotSupportedException - If the superclass clone() method throws it.

getLexicalTokenList

public java.util.List getLexicalTokenList()

Return the list of lexical tokens that were used to make this node.

isCongruent

public boolean isCongruent(ASTPtRootNode node,
                           java.util.Map renaming)

Return true if this node is (hierarchically) congruent to the given node, under the given renaming of bound identifiers. Derived classes should extend this method to add additional necessary congruency checks.

Overrides:

isCongruent in class ASTPtRootNode

Parameters:

node - The node to compare to.

renaming - A map from String to String that gives a renaming from identifiers in this node to identifiers in the given node.

jjtClose

public void jjtClose()

Close this node.

Specified by:

jjtClose in interface Node

Overrides:

jjtClose in class ASTPtRootNode

visit

public void visit(ParseTreeVisitor visitor)
           throws IllegalActionException

Traverse this node with the given visitor.

Overrides:

visit in class ASTPtRootNode

Throws:

IllegalActionException
