Method Detail

addBean

boolean addBean(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

Collection<Object> getBeans()

Returns:

the list of beans known to this aggregate

See Also:

getBean(Class)

getBeans

<T> Collection<T> getBeans(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(), getContainedBeans(Class)

getBean

<T> T getBean(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(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)

unmanage

void unmanage(Object bean)

Unmanages a bean already contained by this aggregate, so that it is not started/stopped/destroyed with this aggregate.

Parameters:

bean - The bean to unmanage (must already have been added).

manage

void manage(Object bean)

Manages a bean already contained by this aggregate, so that it is started/stopped/destroyed with this aggregate.

Parameters:

bean - The bean to manage (must already have been added).

isManaged

boolean isManaged(Object bean)

Test if this container manages a bean

Parameters:

bean - the bean to test

Returns:

whether this aggregate contains and manages the bean

addBean

boolean addBean(Object o,
                boolean managed)

Adds the given bean, explicitly managing it or not.

Parameters:

o - The bean object to add

managed - whether to managed the lifecycle of the bean

Returns:

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

getContainedBeans

<T> Collection<T> getContainedBeans(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 from the entire managed hierarchy
