bsh
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.

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

getArgumentTypes

public java.lang.Class[] getArgumentTypes()

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

---

getReturnType

public java.lang.Object getReturnType()

Get the return type of the method.

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.

---

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.

---

invoke

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

invoke

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

                        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.

invokeImpl

private java.lang.Object invokeImpl(java.lang.Object[] argValues,
                                    Interpreter interpreter,

                             throws EvalError

hasModifier

public boolean hasModifier(java.lang.String name)

---

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).
