Class: module:br/util/ListenerFactory

module:br/util/ListenerFactory

Utility class for creating listener objects that re-route incoming events to a method of your choice.

This class is useful in the following scenarios:

Objects that are only interested in a single event, and don't want to implement the entire interface.
Objects that need to implement the same interface multiple times so they can observe multiple objects — this is only possible using proxy listeners like this.

Construct a new ListenerFactory that can create listeners for the given event, on the given interface.

Name	Type	Description
`interfaceFunc`	function	The listener interface that objects created with this factory will implement.
`eventName`	String	The particular event on the listener interface that will be proxied through.

createListener(call)

Returns a listener that will forward received events through to the given method on the given object.

Name	Type	Description
`call`	function	The call-back to use for the created listener.
