/* Package events provides an event system for Helm.
|
|
*
|
|
* This is not a general purpose event framework. It is a system for handling Helm
|
|
* objects.
|
|
*
|
|
* An event Emitter is an object that binds events and event handlers. An EventHandler
|
|
* is a function that can respond to an event. And a Context is the information
|
|
* passed from the calling location into the event handler. All together, the
|
|
* system works by creating an event emitter, registering event handlers, and
|
|
* then calling the event handlers at the appropriate place and time, passing in
|
|
* a context as you go.
|
|
*
|
|
* In this particular implementation, the Context is considered mutable. So an
|
|
* event handler is allowed to change the contents of the context. It is up to
|
|
* the calling code to decide whether to "accept" those changes back into the
|
|
* calling context.
