Method Summary

Methods

Modifier and Type	Method and Description
void	dispose(Object component) Invoke the "dispose" method on the component instance if this is disposable.
boolean	hasLifecycle(Class<?> type) Test if a component instance has a lifecycle.
boolean	isLazy(ComponentAdapter<?> adapter) Is a component eager (not lazy) in that it should start when start() or equivalent is called, or lazy (it will only start on first getComponent() ).
void	start(Object component) Invoke the "start" method on the component instance if this is startable.
void	stop(Object component) Invoke the "stop" method on the component instance if this is stoppable.

Method Detail

start

void start(Object component)

Invoke the "start" method on the component instance if this is startable. It is up to the implementation of the strategy what "start" and "startable" means.

Parameters:

component - the instance of the component to start

stop

void stop(Object component)

Invoke the "stop" method on the component instance if this is stoppable. It is up to the implementation of the strategy what "stop" and "stoppable" means.

Parameters:

component - the instance of the component to stop

dispose

void dispose(Object component)

Invoke the "dispose" method on the component instance if this is disposable. It is up to the implementation of the strategy what "dispose" and "disposable" means.

Parameters:

component - the instance of the component to dispose

hasLifecycle

boolean hasLifecycle(Class<?> type)

Test if a component instance has a lifecycle.

Parameters:

type - the component's type

Returns:

true if the component has a lifecycle

isLazy

boolean isLazy(ComponentAdapter<?> adapter)

Is a component eager (not lazy) in that it should start when start() or equivalent is called, or lazy (it will only start on first getComponent() ). The default is the first of those two.

Parameters:

adapter -

Returns:

true if lazy, false if not lazy
