subPub

This is a minimal implementation channel based publish subscribe patther, that relay on Angular, that provide a publish subscribe mechanism, but overcome the limitation of data exhange only between parent and childeren. Is simple extend it to implement content type filtering.

The Api provides just: publish subscribe getChannels

Remember: subscribe return a function to unsubscribe the channel (like unsubscription of angular whatch), don't forget to free resources, otherwise you will got memory leaks.

Because the order of execution matter, when you publish on channel where there are no lister a message in console is given to prevent typing error or execution order error.

The demo show how publish to global channel, with specific channel, and how deSubscrbe/freed a channel

	// HOW SUBSCRIBE a channel:
	// pass the callback functiion used to process the data, and optionally the channel name

	// subscribe channel B, with aggiorna function
	// so any data recived on channel, will be passed to aggiorna
	var channelBUnsubscribe= SubPub.subscribe( aggiorna, "B" )

	// subscribe the default shared channel, with aggiorna function
	// so any data recived on channel, will be passed to aggiorna
	var channelSharedUnsubscribe=  SubPub.subscribe( aggiorna )

	// HOW  UnSUBSCRIBE a channel:
	// just fire the function that was returned when you subscribed a channel
	// to prevent memory leaks don't forget to do!
	channelSharedUnsubscribe()

	// HOW  Publish to a channel:
	// just the data, and optionally the channel
	// in case of missing channel parameter the default global channel will be used
	SubPub.publish( "blaBlaBla",'B8')

	// HOW get all the names of channels:
	SubPub.getChannels()
	// a javascript objet will be returned with key to key, 
	// so you can test easily that a channel exist, using key 
	// or use the values if you need the channel list
