Method Summary

java.lang.Object	getInterface(java.lang.Class clasz) Retrieves an instance of java class whose methods are impelemented using procedures in script which are in the intermediate code repository in the underlying interpreter.
java.lang.Object	getInterface(java.lang.Object thiz, java.lang.Class clasz) Retrieves an instance of java class whose methods are impelemented using procedures in script which are in the intermediate code repository in the underlying interpreter.
java.lang.Object	invokeFunction(java.lang.String methodName, java.lang.Object[] args) Invokes a scripting procedure with the given name using the array of objects as its arguments set.
java.lang.Object	invokeMethod(java.lang.Object thiz, java.lang.String methodName, java.lang.Object[] args) Invokes a procedure on an object which already defined in the script using the array of objects as its arguments set.

Method Detail

invokeFunction

java.lang.Object invokeFunction(java.lang.String methodName,
                                java.lang.Object[] args)
                                throws ScriptException,
                                       java.lang.NoSuchMethodException

Invokes a scripting procedure with the given name using the array of objects as its arguments set.

Parameters:

methodName - name of the scripting procedure

args - arguments set for the scripting procedure

Returns:

resultant object after the execution of the procedure

Throws:

ScriptException - if the invocation of the scripting procedure fails

java.lang.NoSuchMethodException

invokeMethod

java.lang.Object invokeMethod(java.lang.Object thiz,
                              java.lang.String methodName,
                              java.lang.Object[] args)
                              throws ScriptException,
                                     java.lang.NoSuchMethodException

Invokes a procedure on an object which already defined in the script using the array of objects as its arguments set.

Parameters:

methodName - name of the procedure to be invoked

thiz - object on which the procedure is called

args - arguments set for the procedure

Returns:

resultant object after the execution of the procedure

Throws:

ScriptException - if the invocation of the procedure fails

java.lang.NoSuchMethodException

getInterface

Parameters:

clasz - an interface which the returned class must implement

Returns:

an instance of the class which implement the specified interface
