This package allows to emit and listen to events using a mediator object.
It provides a class that implements the mediator design pattern to perform operations with objects of classes that abstract emitted events and listeners that process those events when they happened.
Currently it can add a listener to a given event by name, or add a subscriber, get the listeners a given event name, check if a given event name has listeners, remove a listener to a given event, remove a subscriber and trigger a event.

|The mediator pattern allows applications to manage interaction between different types of objects using a single object.
This package can manage events and listeners using a mediator design pattern object to manage all the involved types of objects.
A general event mediator (dispatcher) with minimal dependencies so it is easy to drop in and use.
The recommended way to install Event-Mediator is using Composer from
composer require dragonrun1/event-mediator
You can also get it as a zip file from
Licensing information can be found in the LICENSE file.
Most people might know event mediator as an event dispatcher instead and both
names would have worked. The reason I choose to call it a mediator is it follows
the mediator pattern. For
those of you that are familiar with Symfony 2 and it's
component then Event Mediator started out as basically a drop in replace for it
without the (IMHO) huge dependence overhead often seen with Symfony components.
Event Mediator has since grown into something better since then I think.

* Started new 2.0-dev branch with many BC breaking changes.
* The 1.0 series is now end of life and all application developers should
update to newer 2.0 versions ASAP. If your code only used the listener methods
the move should be easy with few changes needed. If application uses any of
the subscriber stuff you will need to update the returned event array to
reflect the new expected format.
