public class AggregateLifeCycle
extends AbstractLifeCycle
implements Destroyable, Dumpable

An AggregateLifeCycle is an LifeCycle implementation for a collection of contained beans.

Beans can be added the AggregateLifeCycle either as managed beans or as unmanaged beans. A managed bean is started, stopped and destroyed with the aggregate. An unmanaged bean is associated with the aggregate for the purposes of dump(), but it's lifecycle must be managed externally.

When a bean is added, if it is a LifeCycle and it is already started, then it is assumed to be an unmanaged bean. Otherwise the methods addBean(Object, boolean), manage(Object) and unmanage(Object) can be used to explicitly control the life cycle relationship.

If adding a bean that is shared between multiple AggregateLifeCycle instances, then it should be started before being added, so it is unmanaged, or the API must be used to explicitly set it as unmanaged.

AggregateLifeCycle

public AggregateLifeCycle()

方法详细信息

doStart

protected void doStart()
                throws Exception

Start the managed lifecycle beans in the order they were added.

覆盖：

类 AbstractLifeCycle 中的 doStart

抛出：

Exception

另请参见：

AbstractLifeCycle.doStart()

doStop

protected void doStop()
               throws Exception

Stop the joined lifecycle beans in the reverse order they were added.

覆盖：

类 AbstractLifeCycle 中的 doStop

抛出：

Exception

另请参见：

AbstractLifeCycle.doStart()

destroy

public void destroy()

Destroy the joined Destroyable beans in the reverse order they were added.

指定者：

接口 Destroyable 中的 destroy

另请参见：

Destroyable.destroy()

contains

public boolean contains(Object bean)

Is the bean contained in the aggregate.

参数：

bean -

返回：

True if the aggregate contains the bean

isManaged

public boolean isManaged(Object bean)

Is the bean joined to the aggregate.

参数：

bean -

返回：

True if the aggregate contains the bean and it is joined

addBean

public boolean addBean(Object o)

Add an associated bean. If the bean is a LifeCycle, then it will be managed if it is not already started and umanaged if it is already started. The addBean(Object, boolean) method should be used if this is not correct, or the manage(Object) and unmanage(Object) methods may be used after an add to change the status.

参数：

o - the bean object to add

返回：

true if the bean was added or false if it has already been added.

addBean

public boolean addBean(Object o,
                       boolean managed)

Add an associated lifecycle.

参数：

o - The lifecycle to add

managed - True if the LifeCycle is to be joined, otherwise it will be disjoint.

返回：

true if bean was added, false if already present.

manage

public void manage(Object bean)

Manage a bean by this aggregate, so that it is started/stopped/destroyed with the aggregate lifecycle.

参数：

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

unmanage

public void unmanage(Object bean)

Unmanage a bean by this aggregate, so that it is not started/stopped/destroyed with the aggregate lifecycle.

参数：

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

getBeans

public Collection<Object> getBeans()

Get dependent beans

返回：

List of beans.

getBeans

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

Get dependent beans of a specific class

参数：

clazz -

返回：

List of beans.

另请参见：

addBean(Object)

getBean

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

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

参数：

clazz -

返回：

bean or null

另请参见：

addBean(Object)

removeBeans

public void removeBeans()

Remove all associated bean.

removeBean

public boolean removeBean(Object o)

Remove an associated bean.
