java.lang.Object

net.sf.mmm.util.component.base.AbstractComponent

net.sf.mmm.util.component.base.AbstractLoggableComponent

net.sf.mmm.client.ui.base.ComponentContainerContextFallback

All Implemented Interfaces:

ComponentContainer

public class ComponentContainerContextFallback
extends AbstractLoggableComponent
implements ComponentContainer

This is a fake implementation of ComponentContainer used as fallback for AbstractUiContext.getContainer() if no real Ioc is available.

Constructor Detail

ComponentContainerContextFallback

public ComponentContainerContextFallback(AbstractUiContext context)

The constructor.

Parameters:

context - is the AbstractUiContext.

Method Detail

doInitialized

protected void doInitialized()

This method is invoked at the end of the actual initialization. It is called when AbstractComponent.initialize() is invoked for the first time after AbstractComponent.doInitialize() is completed and initialization-state has changed to initialized.
ATTENTION:
When you override this method from a sub-class you need to do a super.AbstractComponent.doInitialized().

Overrides:

doInitialized in class AbstractComponent

get

public <COMPONENT_API> COMPONENT_API get(Class<COMPONENT_API> apiClass)
                                  throws ResourceAmbiguousException,
                                         ResourceMissingException

This method gets the component that realizes the given apiClass.

Specified by:

get in interface ComponentContainer

Type Parameters:

COMPONENT_API - is the generic type of the apiClass.

Parameters:

apiClass - is the class reflecting the API of the requested component. This should be an interface.

Returns:

the requested component.

Throws:

ResourceAmbiguousException - if there are multiple components registered that implement the given apiClass.

ResourceMissingException - if there is no component registered that implements the given apiClass.

get

public <COMPONENT_API> COMPONENT_API get(Class<COMPONENT_API> apiClass,
                                         String componentId)
                                  throws ResourceMissingException

This method gets the component that realizes the given apiClass and is registered under the given componentId.

Specified by:

get in interface ComponentContainer

Type Parameters:

COMPONENT_API - is the generic type of the apiClass.

Parameters:

apiClass - is the class reflecting the API of the requested component. This should be an interface.

componentId - is the unique ID under which the component is registered in this container.

Returns:

the requested component.

Throws:

ResourceMissingException - if there is no component registered under the given componentId or the registered component does NOT realize the given apiClass.

put

public <COMPONENT_API> void put(Class<COMPONENT_API> apiClass,
                                COMPONENT_API componentInstance)

Puts the given componentInstance associated with the given apiClass into this container.
ATTENTION:
This class and especially this method should only be used for initialization of limited environments. Otherwise please prefer proper usage of Cdi.

Type Parameters:

COMPONENT_API - is the generic type of the apiClass.

Parameters:

apiClass - is the class reflecting the API of component. This should be an interface.

componentInstance - is the instance of the component to register.
