java.lang.Object
  bsh.BshMethod

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

DelayedEvalBshMethod

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.

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.

Method Detail

getParameterTypes

public java.lang.Class[] getParameterTypes()

Get the argument types of this method. loosely typed (untyped) arguments will be represented by null argument types.

getParameterNames

public java.lang.String[] getParameterNames()

getReturnType

public java.lang.Class getReturnType()

Get the return type of the method.

Returns:

Returns null for a loosely typed return value, Void.TYPE for a void return type, or the Class of the type.

getModifiers

public Modifiers getModifiers()

getName

public java.lang.String getName()

invoke

public java.lang.Object invoke(java.lang.Object[] argValues,
                               Interpreter interpreter)
                        throws EvalError

Invoke the declared method with the specified arguments and interpreter reference. This is the simplest form of invoke() for BshMethod intended to be used in reflective style access to bsh scripts.

Throws:

EvalError

invoke

public java.lang.Object invoke(java.lang.Object[] argValues,
                               Interpreter interpreter,
                               CallStack callstack)
                        throws EvalError

Invoke the declared method with the specified arguments, interpreter reference, and callstack.

Note: this form of invoke() uses a null Node for the caller and a null node for the CallStack. This method is for scripts performing relective style access to scripted methods.

Throws:

EvalError

invoke

public java.lang.Object invoke(java.lang.Object[] argValues,
                               Interpreter interpreter,
                               CallStack callstack,
                               bsh.SimpleNode callerInfo)
                        throws EvalError

Throws:

EvalError

hasModifier

public boolean hasModifier(java.lang.String name)

toString

public java.lang.String toString()
