JarCastingnext-event
Call a function the next time a specific event is emitted
npm install next-event
Basically like .once but faster since it won't gc the event handler on every event.
Usage
var nextEvent = require('next-event')
var ontest = nextEvent(emitter, 'test')
ontest(function () {
console.log('i am only called once')
})
emitter.emit('test')
emitter.emit('test')
Note that only the last function you pass to ontest in the above example will be called when the next event is emitted
ontest(function () {
console.log('i am never called')
})
ontest(function () {
console.log('i win because i was the last one')
})
emitter.test('test')
API
var once = nextEvent(emitter, name)
Create a new once function. Pass an event handler to once that should be called the next time name is emitted.
