Method Detail

addBean

boolean addBean(java.lang.Object o)

Add a bean. If the bean is-a Container.Listener, then also do an implicit addEventListener(Listener).

Parameters:

o - the bean object to add

Returns:

true if the bean was added, false if it was already present

getBeans

java.util.Collection<java.lang.Object> getBeans()

Returns:

the list of beans known to this aggregate

See Also:

getBean(Class)

getBeans

<T> java.util.Collection<T> getBeans(java.lang.Class<T> clazz)

Type Parameters:

T - the Bean type

Parameters:

clazz - the class of the beans

Returns:

the list of beans of the given class (or subclass)

See Also:

getBeans()

getBean

<T> T getBean(java.lang.Class<T> clazz)

Type Parameters:

T - the Bean type

Parameters:

clazz - the class of the bean

Returns:

the first bean of a specific class (or subclass), or null if no such bean exist

removeBean

boolean removeBean(java.lang.Object o)

Removes the given bean. If the bean is-a Container.Listener, then also do an implicit removeEventListener(Listener).

Parameters:

o - the bean to remove

Returns:

whether the bean was removed

addEventListener

void addEventListener(Container.Listener listener)

Add an event listener.

Parameters:

listener - the listener to add

See Also:

addBean(Object)

removeEventListener

void removeEventListener(Container.Listener listener)

Remove an event listener.

Parameters:

listener - the listener to remove

See Also:

removeBean(Object)
