SteamsProvider

Extends:

Loggable → Errorable → Settingsable → Stateable → Instance → SteamsProvider

Service provider base class.

Example:

	API:
		->add_stream(arg_stream_name, arg_stream=undefined):nothing - register a new stream.
		->remove_stream(arg_stream_name):nothing - unregister a stream.
		->get_stream(arg_stream_name):Stream - get a registered stream.
		->subscribe(arg_stream_name, arg_subscriber)
		->unsubscribe(arg_stream_name, arg_subscriber)
