Method Detail

getPriority

public abstract byte getPriority()

Return the priority.

closeResources

protected abstract void closeResources(SynchronizationPoint<Exception> ondone)

isClosing

public boolean isClosing()

isClosed

public boolean isClosed()

Description copied from interface: CloseableListenable

Return true if closed.

Specified by:

isClosed in interface CloseableListenable

addCloseListener

public void addCloseListener(Listener<CloseableListenable> listener)

Description copied from interface: CloseableListenable

Add a listener to be called once this resource is closed.

Specified by:

addCloseListener in interface CloseableListenable

addCloseListener

public void addCloseListener(Runnable listener)

Description copied from interface: CloseableListenable

Add a listener to be called once this resource is closed.

Specified by:

addCloseListener in interface CloseableListenable

removeCloseListener

public void removeCloseListener(Listener<CloseableListenable> listener)

Description copied from interface: CloseableListenable

Remove a listener.

Specified by:

removeCloseListener in interface CloseableListenable

removeCloseListener

public void removeCloseListener(Runnable listener)

Description copied from interface: CloseableListenable

Remove a listener.

Specified by:

removeCloseListener in interface CloseableListenable

lockClose

public boolean lockClose()

Description copied from interface: IConcurrentCloseable

Calling this method avoid this resource to be closed. For each call to this function, a call to the unlockClose method must be done.

Specified by:

lockClose in interface IConcurrentCloseable

Specified by:

close in interface AutoCloseable

Specified by:

close in interface CloseableListenable

Throws:

Exception

closeAsync

public ISynchronizationPoint<Exception> closeAsync()

Description copied from interface: AsyncCloseable

Close asynchronously.

Specified by:

closeAsync in interface AsyncCloseable<Exception>

operation
