#Broadcast
simple events broadcasting using list of callbacks
methods:
on, off, one, trig, aTrig, clean, events, getAllEvents
Rules for how to use:
- messages can be with any symbol, except ".", because it is identifier for namespace
- namespace MUST BE start from "." symbol. it's for separate from messages
- maximum arguments for .trig() = 3, if you need more arguments for send data, use object structures
examples:
// will create group of events with collision detect
var eventsGroup = broadcast.events('my-group', {
myEv1: 'myEv1',
myEv2: 'myEv2'
})
var eventsGroup2 = broadcast.events('my-group-2', {
myEv1: 'myEv1',
myEv2: 'myEv2'
})
broadcast.trig(evs.myEv1, opt1, opt2); - will trigger message with arguments
// will return evs group
var evs = broadcast.events('my-group');
// bind handler to evs.myEv1 = 'my-group' trigger
broadcast.on(evs.myEv1, function(params){
console.log(params.params1); //see 'ohh now'
});
// 'myHandler' will call only once
broadcast.one('my-event', '.my-namespace', myHandler);
// bind to different messages to 'myHandler'
broadcast.on(['my-event1', 'my-event2'], '.my-namespace', myHandler);
// unbind all callbacks from MESSAGE
broadcast.off('my-event');
unbind all callbacks from NAMESPACE
broadcast.off('.namespace');
// will trigger immedially from current point
broadcast.trig('my-event', {param1: 'ohh now', param2: 2}); // or without params
// will trigger after current callstack is done
broadcast.aTrig('my-event', params);
