Class BasicGenericFactoryMixin

java.lang.Object
  org.objectweb.fractal.julia.factory.BasicGenericFactoryMixin

All Implemented Interfaces:

GenericFactory

public class BasicGenericFactoryMixin

extends Object

implements GenericFactory

Provides a basic implementation of the GenericFactory interface.

Requirements

• the types used in the newFcInstance method must be instances of ComponentType.
• the controller descriptors used in the newFcInstance method must be strings referencing "true descriptors", which are loaded with the _this_weaveableL loader. Here "true descriptors" means controller descriptors as specified in ContextClassGenerator.

Field Summary

Loader	_this_weaveableL The weaveableL field required by this mixin.
TypeFactory	_this_weaveableTF The weaveableTF field required by this mixin.

Constructor Summary

BasicGenericFactoryMixin()

Method Summary

Tree	getFcContentDescriptor(Object contentDesc) Returns the tree corresponding to the given content descriptor.
Tree	getFcControllerDescriptor(Object controllerDesc) Returns the tree corresponding to the given controller descriptor.
Tree	getFcTypeDescriptor(Type type) Returns a tree representing the given component type.
Component	newFcInstance(Type type, Object controllerDesc, Object contentDesc)

Field Detail

_this_weaveableL

public Loader _this_weaveableL

The weaveableL field required by this mixin. This field is supposed to reference the Loader interface of the component to which this controller object belongs.

_this_weaveableTF

public TypeFactory _this_weaveableTF

The weaveableTF field required by this mixin. This field is supposed to reference the TypeFactory interface of the component to which this controller object belongs.

Method Detail

newFcInstance

public Component newFcInstance(Type type,
                               Object controllerDesc,
                               Object contentDesc)
                        throws InstantiationException

Specified by:

newFcInstance in interface GenericFactory

Throws:

InstantiationException

getFcTypeDescriptor

public Tree getFcTypeDescriptor(Type type)
                         throws InstantiationException

Returns a tree representing the given component type. This tree has the format specified in ContextClassGenerator

Parameters:

type - a component type, must be instance of ComponentType.

Returns:

a tree representing the given component type.

Throws:

InstantiationException - if the given type is not an instance of ComponentType, or if it contains control interface types.

getFcControllerDescriptor

public Tree getFcControllerDescriptor(Object controllerDesc)
                               throws InstantiationException

Returns the tree corresponding to the given controller descriptor. This tree is found by using the _this_weaveableL loader. It must have the format specified in ContextClassGenerator

Parameters:

controllerDesc - a string referencing a true controller descriptor.

Returns:

the tree corresponding to the given controller descriptor.

Throws:

InstantiationException - if the tree cannot be loaded.

getFcContentDescriptor

public Tree getFcContentDescriptor(Object contentDesc)

Returns the tree corresponding to the given content descriptor. This tree has the format specified in ContextClassGenerator

Parameters:

contentDesc - a content descriptor.

Returns:

the tree corresponding to the given content descriptor.
