Method Details

getName

@Nonnull
String getName()

Returns the name of this collection.

Specified by:

getName in interface DistributedObject

Returns:

the unique name for this object.

addItemListener

@Nonnull
UUID addItemListener(@Nonnull
 ItemListener<E> listener,
 boolean includeValue)

Adds an item listener for this collection. The listener will be notified of all collection add/remove events.

Listeners are non-destructive: They are notified about changes in a collection, but they won't have any effect on the collection itself. This is particularly relevant for IQueue: A listener won't consume queue elements. It's not a replacement for Queue consumers.

Parameters:

listener - the item listener

includeValue - true if the updated item should be passed to the item listener, false otherwise

Returns:

returns the registration ID

removeItemListener

boolean removeItemListener(@Nonnull
 UUID registrationId)

Removes the specified item listener. Returns silently if the specified listener was not added before.

Parameters:

registrationId - ID of the listener registration

Returns:

true if the item listener is removed, false otherwise
