getInterface
(Class<T> clasz)
Returns an implementation of an interface using functions compiled in
the interpreter. The methods of the interface
may be implemented using the invokeFunction
method.
Parameters
clasz
| The Class object of the interface to return. |
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.

T
getInterface
(Object thiz, Class<T> clasz)
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.
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. |
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.
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.

Object
invokeFunction
(String name, Object... args)
Used to call top-level procedures and functions defined in scripts.
Parameters
args
| Arguments to pass to the procedure or function |
Returns
- The value returned by the procedure or function
Calls a method on a script object compiled during a previous script execution,
which is retained in the state of the ScriptEngine
.
Parameters
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. |
name
| The name of the procedure to be called. |
args
| Arguments to pass to the procedure. The rules for converting
the arguments to scripting variables are implementation-specific. |
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.
