Examples of ListenerList

org.apache.commons.net.util.ListenerList
@author Daniel F. Savarese
org.eclipse.core.runtime.ListenerList
This class is a thread safe list that is designed for storing lists of listeners. The implementation is optimized for minimal memory footprint, frequent reads and infrequent writes. Modification of the list is synchronized and relatively expensive, while accessing the listeners is very fast. Readers are given access to the underlying array data structure for reading, with the trust that they will not modify the underlying array.
A listener list handles the same listener being added multiple times, and tolerates removal of listeners that are the same as other listeners in the list. For this purpose, listeners can be compared with each other using either equality or identity, as specified in the list constructor.
Use the getListeners method when notifying listeners. The recommended code sequence for notifying all registered listeners of say, FooListener.eventHappened, is:
```
 Object[] listeners = myListenerList.getListeners(); for (int i = 0; i < listeners.length; ++i) { ((FooListener) listeners[i]).eventHappened(event); } 
```
This class can be used without OSGi running.

org.eclipse.jface.util.ListenerList
This class is used to maintain a list of listeners, and is used in the implementations of several classes within JFace which allow you to register listeners of various kinds. It is a fairly lightweight object, occupying minimal space when no listeners are registered.
Note that the add method checks for and eliminates duplicates based on identity (not equality). Likewise, the remove method compares based on identity.

Use the getListeners method when notifying listeners. Note that no garbage is created if no listeners are registered. The recommended code sequence for notifying all registered listeners of say, FooListener.eventHappened, is:
```
 Object[] listeners = myListenerList.getListeners(); for (int i = 0; i < listeners.length; ++i) { ((FooListener) listeners[i]).eventHappened(event); } 
```
@deprecated Please use {@link org.eclipse.core.runtime.ListenerList} instead.Please note that the {@link #ListenerList(int)} and{@link org.eclipse.core.runtime.ListenerList#ListenerList(int)}constructors have different semantics. Please read the javadoc carefully. Also note that the equivalent of {@link #ListenerList()} is actually{@link org.eclipse.core.runtime.ListenerList#ListenerList(int)}with {@link org.eclipse.core.runtime.ListenerList#IDENTITY} asthe argument.

Manages a thread-safe list of {@link RepositoryListener}s.
