Class PythonBaseFactory<T extends Assembler>

java.lang.Object

org.apache.turbine.services.assemblerbroker.util.python.PythonBaseFactory<T>

Type Parameters:

T - the specialized assembler type

All Implemented Interfaces:

Loader<T>, AssemblerFactory<T>

Direct Known Subclasses:

PythonActionFactory, PythonLayoutFactory, PythonNavigationFactory, PythonPageFactory, PythonScreenFactory

public abstract class PythonBaseFactory<T extends Assembler>
extends Object
implements AssemblerFactory<T>

A factory that attempts to load a python class in the JPython interpreter and execute it as a Turbine screen. The JPython script should inherit from Turbine Screen or one of its subclasses.
