Class BasicFactory

java.lang.Object
  org.objectweb.fractal.adl.BasicFactory

All Implemented Interfaces:

BindingController, Factory

public class BasicFactory

extends Object

implements BindingController, Factory

Basic implementation of the Factory interface. This implementation uses a Loader to load ADL definitions, a Compiler to compile them, and a Scheduler to execute the compiled tasks.

Field Summary

Compiler	compiler The Compiler used by this factory.
static String	COMPILER_BINDING Name of the client interface bound to the Compiler used by this factory.
Loader	loader The Loader used by this factory.
static String	LOADER_BINDING Name of the client interface bound to the Loader used by this factory.
org.objectweb.deployment.scheduling.core.api.Scheduler	scheduler The Scheduler used by this factory.
static String	SCHEDULER_BINDING Name of the client interface bound to the Scheduler used by this factory.

Constructor Summary

BasicFactory()

Method Summary

void	bindFc(String itf, Object value)
String[]	listFc()
Object	lookupFc(String itf)
Object	newComponent(String name, Map context) Creates a new instance of the component whose name is given.

                   Object value)

newComponent

public Object newComponent(String name,
                           Map context)
                    throws ADLException

Description copied from interface: Factory

Creates a new instance of the component whose name is given. This can be done by loading the ADL definition of this name, by compiling it into a set of tasks and by executing these tasks in the proper order.

Specified by:

newComponent in interface Factory

Parameters:

name - the name of the component to be created.

context - optional additional information.

Returns:

the component that has been created. The type of this result depends on the implementation of this interface: it can be a Fractal component reference (if this factory creates Fractal components), it can be an identifier (if this factory generates source code that will create components, instead of directly creating components), etc.

Throws:

ADLException - if a problem occurs during the creation of the component.
