Stoppable

A library for working with stoppables. Stoppables are similar to promises or futures. In addition, they can be stopped. This library can save add-on developers some work.

Things included

• Stoppable.Stoppable: the class for the stoppable construct.
• Stoppable.Stoppable.new: the constructor for the Stoppable class.
• Stoppable.all: returns a new stoppable that when stopped also stops all given stoppables.

Methods:

• hasBeenRequestedToStop: returns if the stoppable has been requested to stop.
• isRunning: returns if the stoppable is running.
• hasStopped: returns if the stoppable has stopped.
• stop: requests that the stoppable stops.
• alsoStop: registers another stoppable to also stop.
• onStop: registers a callback that is run after "stop" has been called.
• afterStop: registers a callback that is run after the stoppable has stopped.

Private methods (are returned as the second return value of the constructor):

• resolve: resolves the stoppable with the given values and marks it as stopped.
