ListenersManager

interface ListenersManager<in Interface : Any>

An object that allows to register (and unregister) listeners.

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. `abstract fun addStrongly(listener: Interface): Unit`
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. `abstract fun addWeakly(listener: Interface): Unit`
contains	Returns whether or not the given listener is contained in this listener manager `abstract fun contains(listener: Interface): Boolean`
remove	Removes the specified listener. `abstract fun remove(listener: Interface): Unit`

BaseListenersManager	Base implementation for ListenersManager. `abstract class BaseListenersManager<Interface : Any> : FlexibleSet<Interface>, ListenersManager<Interface>`
CallableListenersManager	A CallableListenersManager allows to invoke methods on registered listeners, by using call. `interface CallableListenersManager<Interface : Any> : ListenersManager<Interface>`
NoOpListenersManager	A ListenersManager that does nothing. It can be used in situations where it is known that listeners won't ever be invoked `object NoOpListenersManager : ListenersManager<Any>`
