java.lang.Object
   org.jicarilla.lang.AbstractActive

All known Subclasses:   org.jicarilla.lang.AbstractExecutable,  org.jicarilla.net.SocketServerImpl,
AbstractActive
abstract public class AbstractActive implements Active(Code)
Fault-tolerant Active class which synchronizes initialize() and dispose() and will silently ignore repeated or otherwise inappropriate calls to either method, thus freeing subclasses from the need to check against repeated calls. Furthermore, it contains several protected utility methods that allow you to implement both the state checking and lazy initialization code patterns described in the documentation for the Active interface.

Field Summary
protected  booleanm_running
     Whether we're running.
protected  booleanm_stopped
     Whether we've stopped.


Method Summary
final protected synchronized  voidcheckActive()
     Check whether we're active.
final public synchronized  voiddispose()
     Dispose of the component.
protected  voiddoDispose()
     This method is called from dispose().
protected  voiddoInitialize()
     This method is called from initialize().
final public synchronized  voidinitialize()
     Intialize the component.
final protected synchronized  booleanisActive()
     Check whether we're active.
final protected synchronized  booleanisDisposed()
     Check whether we're disposed.
final protected synchronized  booleanisInitialized()
     Check whether we're initialized.
final protected synchronized  voidlazyInitialization()
     Helps implement lazy initialization (and even re-initialization if we implement org.jicarilla.lang.Recyclable ).

Field Detail
m_running
protected boolean m_running(Code)
Whether we're running.



m_stopped
protected boolean m_stopped(Code)
Whether we've stopped.





Method Detail
checkActive
final protected synchronized void checkActive()(Code)
Check whether we're active.
throws:
  AssertionError - if we're not active



dispose
final public synchronized void dispose() throws Throwable(Code)
Dispose of the component.
throws:
  Throwable - in case of a problem.
See Also:    org.jicarilla.lang.Active@dispose()



doDispose
protected void doDispose() throws Throwable(Code)
This method is called from dispose(). Override it in subclasses to implement 'active' behaviour. There's no need to call the base method.
throws:
  Throwable - in case of a problem.



doInitialize
protected void doInitialize() throws Throwable(Code)
This method is called from initialize(). Override it in subclasses to implement 'active' behaviour. There's no need to call the base method.
throws:
  Throwable - in case of a problem.



initialize
final public synchronized void initialize() throws Throwable(Code)
Intialize the component.
throws:
  Throwable - in case of a problem.
See Also:   org.jicarilla.lang.Active.initialize



isActive
final protected synchronized boolean isActive()(Code)
Check whether we're active. true if we are, false otherwise.



isDisposed
final protected synchronized boolean isDisposed()(Code)
Check whether we're disposed. true if we are, false otherwise.



isInitialized
final protected synchronized boolean isInitialized()(Code)
Check whether we're initialized. true if we are, false otherwise.



lazyInitialization
final protected synchronized void lazyInitialization() throws Throwable(Code)
Helps implement lazy initialization (and even re-initialization if we implement org.jicarilla.lang.Recyclable ). Call this method on the first line of all the public (and optionally all protected) methods in your subclass.
throws:
  Throwable - if an exception occurs during AbstractActive.initialize()
throws:
  AssertionError - if we've been disposed of and we don't implementRecyclable
