Method Detail

• addLookupListener

  public abstract void addLookupListener​(LookupListener l)

  Registers a listener that is invoked when there is a possible change in this result.

  Sometimes people report that their listener is not receiving events (for example IZ 191471) or that the listener receives few events, but then it stops listening. Such behavior is often caused by not keeping strong reference to the Lookup.Result object. When it gets garbage collected it can no longer deliver events. Thus remember to keep reference to the object you are attaching listener to.

  Parameters:

  l - the listener to add

• removeLookupListener

  public abstract void removeLookupListener​(LookupListener l)

  Unregisters a listener previously added.

  Parameters:

  l - the listener to remove

• allInstances

  public abstract java.util.Collection<? extends T> allInstances​()

  Get all instances in the result. The return value type should be List instead of Collection, but it is too late to change it.

  Returns:

  unmodifiable collection of all instances that will never change its content

• allClasses

  public java.util.Set<java.lang.Class<? extends T>> allClasses​()

  Get all classes represented in the result. That is, the set of concrete classes used by instances present in the result. All duplicate classes will be omitted.

  Returns:

  unmodifiable set of Class objects that will never change its content

• allItems

  public java.util.Collection<? extends Lookup.Item<T>> allItems​()

  Get all registered items. This should include all pairs of instances together with their classes, IDs, and so on. The return value type should be List instead of Collection, but it is too late to change it.

  Returns:

  unmodifiable collection of Lookup.Item that will never change its content
