public class AggregateLifeCycle
extends AbstractLifeCycle
implements Destroyable, Dumpable

An AggregateLifeCycle is an AbstractLifeCycle with a collection of dependent beans.

Dependent beans are started and stopped with the LifeCycle and if they are destroyed if they are also Destroyable.

addBean

public boolean addBean(Object o)

Add an associated bean. The bean will be added to this LifeCycle and if it is also a LifeCycle instance, it will be started/stopped. Any beans that are also Destroyable, will be destroyed with the server.

Parameters:

o - the bean object to add

getBeans

public Collection<Object> getBeans()

Get dependent beans

Returns:

List of beans.

getBeans

public <T> List<T> getBeans(Class<T> clazz)

Get dependent beans of a specific class

Parameters:

clazz -

Returns:

List of beans.

See Also:

addBean(Object)

getBean

public <T> T getBean(Class<T> clazz)

Get dependent bean of a specific class. If more than one bean of the type exist, the first is returned.

Parameters:

clazz -

Returns:

bean or null
