componentHasLifecycle
public boolean componentHasLifecycle()Description copied from class:AbstractBehavior
Invokes delegate hasLifecycle method if the delegate is a Behavior Test if a component honors a lifecycle.- Specified by:
componentHasLifecycle
in interfaceComponentLifecycle<T>
- Overrides:
componentHasLifecycle
in classAbstractBehavior<T>
- Returns:
true
if the component has a lifecycle
-
dispose
Disposes the cached component instance Invokes delegate dispose method if the delegate is a Behavior Invoke the "dispose" method on the component.- Specified by:
dispose
in interfaceComponentLifecycle<T>
- Overrides:
dispose
in classAbstractBehavior<T>
- Parameters:
container
- the container to "dispose" the component
-
getStoredObject
Retrieves the stored reference. May be null if it has never been set, or possibly if the reference has been flushed.- Returns:
- the stored object or null.
-
flush
public void flush()Flushes the cache. If the component instance is started is will stop and dispose it before flushing the cache. -
getComponentInstance
Description copied from interface:ComponentAdapter
Retrieve the component instance. This method will usually create a new instance each time it is called, but that is not required. For example,Cached
will always return the same instance.- Specified by:
getComponentInstance
in interfaceComponentAdapter<T>
- Overrides:
getComponentInstance
in classAbstractBehavior<T>
- Parameters:
container
- thePicoContainer
, that is used to resolve any possible dependencies of the instance.into
- the class that is about to be injected into. Use ComponentAdapter.NOTHING.class if this is not important to you.- Returns:
- the component instance.
- Throws:
PicoCompositionException
- if the component has dependencies which could not be resolved, or instantiation of the component lead to an ambiguous situation within the container.
-
getDescriptor
Description copied from interface:ComponentAdapter
Get a string key descriptor of the component adapter for use in toString()- Returns:
- the descriptor
-
getLifecycleDescriptor
-
start
Starts the cached component instance Invokes delegate start method if the delegate is a Behavior Invoke the "start" method on the component.- Specified by:
start
in interfaceComponentLifecycle<T>
- Overrides:
start
in classAbstractBehavior<T>
- Parameters:
container
- the container to "start" the component
-
stop
Stops the cached component instance Invokes delegate stop method if the delegate is a Behavior Invoke the "stop" method on the component.- Specified by:
stop
in interfaceComponentLifecycle<T>
- Overrides:
stop
in classAbstractBehavior<T>
- Parameters:
container
- the container to "stop" the component
-
isStarted
public boolean isStarted()- Specified by:
isStarted
in interfaceComponentLifecycle<T>
- Overrides:
isStarted
in classAbstractBehavior<T>
