Interface HandlerContainer

All Known Implementing Classes:

HandlerContainerImpl, Presenter, PresenterWidget, RootPresenter, TabContainerPresenter

public interface HandlerContainer

A class that can contain handlers. Handlers can be registered when the object is being bound, or at any time while it is bound. They will be automatically unregistered when the class is unbound.

For details on the autobinding mechanism, see HandlerContainerImpl.

Method Summary

Methods

Modifier and Type	Method and Description
void	bind() Call this method after the object is constructed in order to bind all its handlers.
boolean	isBound() Returns true if the HandlerContainer is currently bound.
void	unbind() Call this method when you want to release the object and its handlers are not needed anymore.

Method Detail

bind

void bind()

Call this method after the object is constructed in order to bind all its handlers. You should never call bind() from the constructor of a non-leaf class since it is meant to be called after the object has been entirely constructed.

When automatic binding is used (see HandlerContainerImpl), this will be called immediately after the object is constructed through Guice/GIN dependency injection mechanism.

If you are not using automatic binding, or if you later call unbind() on this object, you will have to call bind() manually.

Multiple call to bind will not fail, the class will be bound once.

isBound

boolean isBound()

Returns true if the HandlerContainer is currently bound. That is, the bind() method has completed and unbind() has not been called.

Returns:

true if bound, false otherwise.

unbind

void unbind()

Call this method when you want to release the object and its handlers are not needed anymore. You will have to call bind() again manually if you ever want to reuse the object.
