Class ASTPtSumNode
java.lang.Object
ptolemy.data.expr.ASTPtRootNode
ptolemy.data.expr.ASTPtSumNode
- All Implemented Interfaces:
- java.lang.Cloneable, Node
public class ASTPtSumNode
- extends ASTPtRootNode
The parse tree created from the expression string consists of a
hierarchy of node objects. This class represents sum(+, -) nodes in
the parse tree.

clone()
Clone the parse tree node by invoking the clone() method of
the base class. |

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

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
