Invocable JDK 1.6)

public T getInterface (Class< T> clasz)

Returns an implementation of an interface using functions compiled in the interpreter.

Returns an implementation of an interface using functions compiled in
the interpreter. The methods of the interface
may be implemented using the invokeFunction method.
Returns: An instance of requested interface - null if the requested interface is unavailable, i. e. if compiled functions in the ScriptEngine cannot be found matching the ones in the requested interface.
Parameters:
- clasz - The Class object of the interface to return.
Throws:
- IllegalArgumentException - if the specified Class object is null or is not an interface.

public T getInterface (Object thiz, Class< T> clasz)

Returns an implementation of an interface using member functions of a scripting object compiled in the interpreter.

Returns an implementation of an interface using member functions of
a scripting object compiled in the interpreter. The methods of the
interface may be implemented using the invokeMethod method.
Returns: An instance of requested interface - null if the requested interface is unavailable, i. e. if compiled methods in the ScriptEngine cannot be found matching the ones in the requested interface.
Parameters:
- thiz - The scripting object whose member functions are used to implement the methods of the interface.
- clasz - The Class object of the interface to return.
Throws:
- IllegalArgumentException - if the specified Class object is null or is not an interface, or if the specified Object is null or does not represent a scripting object.

public Object invokeFunction (String name, Object args) throws ScriptException NoSuchMethodException

Used to call top-level procedures and functions defined in scripts.

public Object invokeMethod (Object thiz, String name, Object args) throws ScriptException NoSuchMethodException

Calls a method on a script object compiled during a previous script execution, which is retained in the state of the ScriptEngine.

Calls a method on a script object compiled during a previous script execution,
which is retained in the state of the ScriptEngine.
Returns: The value returned by the procedure. The rules for converting the scripting variable returned by the script method to a Java Object are implementation-specific.
Parameters:
- 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.
Throws:
- ScriptException - if an error occurrs 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.
