Class BshMethod

java.lang.Object
  |
  +--bsh.BshMethod

All Implemented Interfaces:

java.io.Serializable

public class BshMethod

extends java.lang.Object

implements java.io.Serializable

This represents an *instance* of a bsh method declaration in a particular namespace. This is a thin wrapper around the BSHMethodDeclaration with a pointer to the declaring namespace.

The issue is that when a method is located in a subordinate namespace or invoked from an arbitrary namespace it must nontheless execute with its 'super' as the context in which it was declared. i.e. The local method context is a child namespace of the declaring namespace.

                                throws EvalError

Invoke the bsh method with the specified args, interpreter ref, and callstack. callerInfo is the node representing the method invocation It is used primarily for debugging in order to provide access to the text of the construct that invoked the method through the namespace.

Parameters:

callerInfo - is the node representing the method invocation This is used primarily for debugging and may be null.

callstack - is the callstack of course. If you are using a hacked version of BeanShell that exposed this method take a look at NameSpace invokeMethod to see how to make a fake callstack...
