Class BasicTemplateMixin

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

All Implemented Interfaces:

Controller, Factory, Template

public abstract class BasicTemplateMixin

extends Object

implements Controller, Template

Provides a basic implementation of the Template interface.

Requirements (here "sub template" means "any direct or indirect sub template")

• the type of this template component must be an instance of ComponentType.
• all the sub templates of this template component must provide the Template interface (and the Component interface).
• if this template component, or one of its sub templates, has a ContentController interface, then the components instantiated by this template component must also have the ContentController interface. Likewise for the BindingController interface.
• For each binding between template components, the server interface must implement the Interface interface. Moreover, the owner of this interface must be a (sub) template of this template component.

Field Summary

Component	_this_weaveableC The weaveableC field required by this mixin.
Object[]	fcContent The controller and content descriptors of the components instantiated by this template.

Object	getFcContentDesc() Returns a description of the content part of the components instantiated by this factory.
Object	getFcControllerDesc() Returns a description of the controller part of the components instantiated by this factory.
Type	getFcInstanceType() Returns the functional type of the components instantiated by this factory.
void	initFcController(InitializationContext ic) Initializes the fields of this mixin and then calls the overriden method.

Field Detail

fcInstanceType

public Type fcInstanceType

The functional type of the components instantiated by this template.

fcContent

public Object[] fcContent

The controller and content descriptors of the components instantiated by this template.

_this_weaveableC

public Component _this_weaveableC

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

Method Detail

initFcController

public void initFcController(InitializationContext ic)
                      throws InstantiationException

Initializes the fields of this mixin and then calls the overriden method.

Specified by:

initFcController in interface Controller

Parameters:

ic - information about the component to which this controller object belongs.

Throws:

InstantiationException - if the initialization fails.

getFcInstanceType

public Type getFcInstanceType()

Description copied from interface: Factory

Returns the functional type of the components instantiated by this factory.

Specified by:

getFcInstanceType in interface Factory

Returns:

the functional type of the components instantiated by this factory.

getFcControllerDesc

public Object getFcControllerDesc()

Description copied from interface: Factory

Returns a description of the controller part of the components instantiated by this factory.

Specified by:

getFcControllerDesc in interface Factory

Returns:

a description of the controller part of the components instantiated by this factory. This description is implementation specific. If it is null then a "default" controller part will be used.

getFcContentDesc

public Object getFcContentDesc()

Description copied from interface: Factory

Returns a description of the content part of the components instantiated by this factory.

Specified by:

getFcContentDesc in interface Factory

Returns:

a description of the content part of the components instantiated by this factory. This description is implementation specific. It may be null to create component with an empty initial content. It may also be, in Java, the fully qualified name of a Java class, to creat primitive components.

newFcInstance

public Component newFcInstance()
                        throws InstantiationException

Description copied from interface: Factory

Instantiates a component from this factory.

Specified by:

newFcInstance in interface Factory

Returns:

the Component interface of the component instantiated from this factory.

Throws:

InstantiationException - if the component cannot be created.

newFcControllerInstance

public Component newFcControllerInstance()
                                  throws InstantiationException

Description copied from interface: Template

Instantiates only the controller part of the component normally instantiated by this template. Because of component sharing, the newFcInstance method cannot be implemented by just calling itself recursively on the sub templates of this template (otherwise some sub templates may be instantiated several times). Hence this method.

Specified by:

newFcControllerInstance in interface Template

Returns:

the instantiated component.

Throws:

InstantiationException - if the component controller cannot be instantiated.

_super_initFcController

public abstract void _super_initFcController(InitializationContext i)
                                      throws InstantiationException

The initFcController method overriden by this mixin.

Throws:

InstantiationException
