BaseListenersManager

<init>

Base implementation for ListenersManager.

baseListenersManagerSynchronizer

hasListeners

Whether this ListenersManager has associated listeners

hasStrongListeners

addStrongly

Adds a listener, keeping a strong reference. This means that if nobody else keeps a pointer to the listener, it won't be disposed by the Garbage Collector and will be kept in this object forever.

addStronglyWithoutCallingHasListeners

Adds the given listener strongly, like addStrongly. However, if doing so would have called the onHasListenersChanges lambda, this method won't call it, and returns true. When this happens, you must call notifyHasListeners

addWeakly

Adds a listener, keeping a weak reference. This means that if nobody else keeps a pointer to the listener, it'll at some point automatically disposed by the Garbage Collector.

addWeaklyWithoutCallingHasListeners

Adds the given listener weakly, like addWeakly. However, if doing so would have called the onHasListenersChanges lambda, this method won't call it, and returns true. When this happens, you must call notifyHasListeners

callListeners

Use this method to invoke some method on the currently attached listeners.

contains

Returns whether or not the given listener is contained in this listener manager

notifyHasListeners

You must call this method if addWeaklyWithoutCallingHasListeners or removeWithoutCallingHasListeners or addStronglyWithoutCallingHasListeners returned true

onHasListenersChanges

Callback that will be called after hasListeners changes.

onHasListenersChangesImmediate

Callback that will be called immediately after hasListeners or hasStrongListeners change. This method will be executed in a synchronized context, so it's important to not acquire additional locks.

remove

Removes the specified listener.

removeWithoutCallingHasListeners

Removes the given listener, like remove. However, if doing so would have called the onHasListenersChanges lambda, this method won't call it, and returns true. When this happens, you must call notifyHasListeners

ReflectionListenersManager

This implementation of ListenersManager is the easiest to use. Through reflection, it is possible to use it without the need to write any custom code.
