public interface Invocable
| Modifier and Type | Method and Description | 
|---|---|
| <T> T | getInterface(Class<T> clasz)Returns an implementation of an interface using functions compiled in
 the interpreter. | 
| <T> T | getInterface(Object thiz,
            Class<T> clasz)Returns an implementation of an interface using member functions of
 a scripting object compiled in the interpreter. | 
| Object | invokeFunction(String name,
              Object... args)Used to call top-level procedures and functions defined in scripts. | 
| Object | invokeMethod(Object thiz,
            String name,
            Object... args)Calls a method on a script object compiled during a previous script execution,
 which is retained in the state of the  ScriptEngine. | 
Object invokeMethod(Object thiz, String name, Object... args) throws ScriptException, NoSuchMethodException
ScriptEngine.name - The name of the procedure to be called.thiz - If the procedure is a member  of a class
 defined in the script and thiz is an instance of that class
 returned by a previous execution or invocation, the named method is
 called through that instance.args - Arguments to pass to the procedure.  The rules for converting
 the arguments to scripting variables are implementation-specific.ScriptException - if an error occurs during invocation of the method.NoSuchMethodException - if method with given name or matching argument types cannot be found.NullPointerException - if the method name is null.IllegalArgumentException - if the specified thiz is null or the specified Object is
 does not represent a scripting object.Object invokeFunction(String name, Object... args) throws ScriptException, NoSuchMethodException
