Constructor Detail

LifeCycleAutomatonImpl

public LifeCycleAutomatonImpl()

Empty constructor, such LifeCycleComponent.LifeCycleAutomaton cannot do much more than decline the various LifeCycleStatus states for you.

LifeCycleAutomatonImpl

public LifeCycleAutomatonImpl(LifeCycleComponent aLifeCycleComponent)

This constructor uses a LifeCycleStatus for wrapping it inside the LifeCycleAutomatonImpl, making sure of obeying and guarding the correct LifeCycleStatus's order of LifeCycleStatus states for you.

Parameters:

aLifeCycleComponent - The component to be guarded regarding the correct declination of the LifeCycleStatus states.

Method Detail

getLifeCycleStatus

public LifeCycleStatus getLifeCycleStatus()

Description copied from interface: LifeCycleStatusAccessor

Retrieves the LifeCycleStatus property from the property. Determines in which LifeCycleStatus status a component is in.

Specified by:

getLifeCycleStatus in interface LifeCycleStatusAccessor

Returns:

Returns the LifeCycleStatus property stored by the property.

initialize

public void initialize()
                throws InitializeException

Description copied from interface: Initializable

Initialize the component.

Specified by:

initialize in interface Initializable

Throws:

InitializeException - Thrown in case initializing fails.

isInitalizable

public boolean isInitalizable()

Description copied from interface: Initializable.InitializeAutomaton

Determines whether the component may get initialized.

Specified by:

isInitalizable in interface Initializable.InitializeAutomaton

Returns:

True if Initializable.initialize() is possible.

isInitialized

public boolean isInitialized()

Description copied from interface: InitializedAccessor

Retrieves the is-initialized property from the initialized property. Determines whether the component is initialized. A component is initialized after being initialized as of Initializable.initialize() or Configurable.initialize(Object).

Specified by:

isInitialized in interface InitializedAccessor

Returns:

True in case of being initialized (returns the is-initialized property stored by the initialized property).

isStartable

public boolean isStartable()

Description copied from interface: Startable.StartAutomaton

Determines whether the component may get started.

Specified by:

isStartable in interface Startable.StartAutomaton

Returns:

True if Startable.start() is possible.

start

public void start()
           throws StartException

Description copied from interface: Startable

Starts the component.

Specified by:

start in interface Startable

Throws:

StartException - Thrown in case starting fails.

isRunning

public boolean isRunning()

Description copied from interface: RunningAccessor

Retrieves the is-running property from the running property. Determines whether the component is running. A component is running after being started or being resumed as of Startable.start() or Resumable.resume().

Specified by:

isRunning in interface RunningAccessor

Returns:

True in case of being resumed or started (returns the is-running property stored by the running property).

isPausable

public boolean isPausable()

Description copied from interface: Pausable.PauseAutomaton

Determines whether the component may get paused.

Specified by:

isPausable in interface Pausable.PauseAutomaton

Returns:

True if Pausable.pause() is possible.

pause

public void pause()
           throws PauseException

Description copied from interface: Pausable

Pauses the component.

Specified by:

pause in interface Pausable

Throws:

PauseException - in case pausing fails.

isPaused

public boolean isPaused()

Description copied from interface: Pausable.PauseAutomaton

Determines whether the component is paused.

Specified by:

isPaused in interface Pausable.PauseAutomaton

Returns:

True in case of being paused, else false.

isResumable

public boolean isResumable()

Description copied from interface: Resumable.ResumeAutomaton

Determines whether the component may get resumed.

Specified by:

isResumable in interface Resumable.ResumeAutomaton

Returns:

True if Resumable.resume() is possible.

resume

public void resume()
            throws ResumeException

Description copied from interface: Resumable

Resumes the component.

Specified by:

resume in interface Resumable

Throws:

ResumeException - Thrown in case resuming fails.

isStoppable

public boolean isStoppable()

Description copied from interface: Stoppable.StopAutomaton

Determines whether the component may get stopped.

Specified by:

isStoppable in interface Stoppable.StopAutomaton

Returns:

True if Stoppable.stop() is possible.

stop

public void stop()
          throws StopException

Description copied from interface: Stoppable

Stops the component.

Specified by:

stop in interface Stoppable

Throws:

StopException - Thrown in case stopping fails.

isStopped

public boolean isStopped()

Description copied from interface: Stoppable.StopAutomaton

True in case of being stopped, else false.

isDestroyable

public boolean isDestroyable()

Description copied from interface: Destroyable.DestroyAutomaton

Determines whether the component may get destroyed.

Specified by:

isDestroyable in interface Destroyable.DestroyAutomaton

Returns:

True if Destroyable.destroy() is possible.

destroy

public void destroy()

Description copied from interface: Destroyable

Destroys the component. External resources might stay untouched! This should always be possible and must not throw any exception. In case a Component has been destroyed, then invoking any of that Component instance's methods (except the Destroyable.destroy() method) must throw an IllegalStateException as by definition a once destroyed Component is in the state of being destroyed which is irreversible.

Specified by:

destroy in interface Destroyable

isDestroyed

public boolean isDestroyed()

Description copied from interface: Destroyable.DestroyAutomaton

Determines whether the component is destroyed. In case of being true, then invoking any of that Component instance's methods (except the Destroyable.destroy() method) must throw an IllegalStateException as by definition a once destroyed Component is in the state of being destroyed which is irreversible.

Specified by:

isDestroyed in interface Destroyable.DestroyAutomaton

Returns:

True in case of being destroyed, else false.

getLifeCycleComponent

protected LifeCycleComponent getLifeCycleComponent()

Provides access to the LifeCycleComponent instance.

Returns:

The LifeCycleComponent instance being set.
