Class BshMethod

java.lang.Object

bsh.BshMethod

All Implemented Interfaces:

BshClassManager.Listener, java.io.Serializable, java.lang.Cloneable

Direct Known Subclasses:

DelayedEvalBshMethod

public class BshMethod
extends java.lang.Object
implements java.io.Serializable, java.lang.Cloneable, BshClassManager.Listener

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 nonetheless execute with its 'super' as the context in which it was declared.

Method Detail

clone

public BshMethod clone()

Cloneable clone method implementation, delegated to parent.

Overrides:

clone in class java.lang.Object

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()

getParameterModifiers

public Modifiers[] getParameterModifiers()

getParameterCount

public int getParameterCount()

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()

isVarArgs

public boolean isVarArgs()

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,
                               Node callerInfo)
                        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 BeanShell AST node representing the method invocation. It is used to print the line number and text of errors in EvalError exceptions. If the node is null here error messages may not be able to point to the precise location and text of the error.

callstack - is the callstack. If callstack is null a new one will be created with the declaring namespace of the method on top of the stack (i.e. it will look for purposes of the method invocation like the method call occurred in the declaring (enclosing) namespace in which the method is defined).

Throws:

EvalError

hasModifier

public boolean hasModifier(java.lang.String name)

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

equal

protected static boolean equal(java.lang.Object obj1,
                               java.lang.Object obj2)

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

classLoaderChanged

public void classLoaderChanged()

Specified by:

classLoaderChanged in interface BshClassManager.Listener
