ASTPtFunctionApplicationNode

java.lang.Object
- ptolemy.data.expr.ASTPtRootNode
- - ptolemy.data.expr.ASTPtFunctionApplicationNode

All Implemented Interfaces:

java.lang.Cloneable, Node
```
public class ASTPtFunctionApplicationNode
extends ASTPtRootNode
```
This class represents an expression that is the application of a function in the parse tree. The first child of this node is the child node that represents the function. The function specification may any node that evaluates to a FunctionToken, or a leaf node that refers to the name of a function registered with the parser. The remaining children are node representing the arguments of the function. For information on the evaluation of functions, refer to ParseTreeEvaluator.visitFunctionApplicationNode(ptolemy.data.expr.ASTPtFunctionApplicationNode).
