Class SubDefinitionNode  

java.lang.Object
  com.tripi.asp.SubDefinitionNode

All Implemented Interfaces:

FunctionNode, Node

---

public class SubDefinitionNode

extends java.lang.Object

implements FunctionNode

SubDefinitionCode contains the parsed representation of a subroutine definition, also includes function definition syntax.

Field Summary
(package private)  BlockNode	block           Code within the function
(package private) static org.apache.log4j.Category	DBG           Debugging category
(package private)  IdentNode	ident           Name of the subroutine/function
(package private)  VarListNode	identlist           Parameter list to the function
(package private)  boolean	isFunction           true if this is a function, false otherwise

 

Constructor Summary

SubDefinitionNode(IdentNode ident, VarListNode identlist, BlockNode block, boolean isFunction)           Constructor.

 

Method Summary
void	dump()           Dumps the string representation of this subroutine definition.
java.lang.Object	execute(AspContext scope)           Executes this subroutine, the subroutine definition itself has no effect when executed.
java.lang.Object	execute(VarListNode param, AspContext scope)           This function executes the subroutine/function itself.
BlockNode	getBlock()           Get the block of this subroutine.
IdentNode	getIdent()           Get the identifier of this subroutine.
VarListNode	getIdentList()           Get the list of parameters for this subroutine.
boolean	isFunction()           Is this a function?
void	prepare(AspContext scope)           Prepares this subroutine, it effectively defines this subroutine within the global scope.
