/**
|
|
* Processing chain provides a framework for connecting a complex or real sample
|
|
* source to a set of one primary decoder and zero or more auxiliary decoders.
|
|
* All decoded messages and call events produced by the decoders and the decoder
|
|
* call states are aggregated by the various broadcasters. You can register
|
|
* listeners to receive aggregated messages, call events, and audio packets.
|
|
*
|
|
* Normal setup sequence:
|
|
*
|
|
* 1) Add one or more modules
|
|
* 2) Register listeners to receive messages, call events, audio, etc.
|
|
* 3) Add a valid source
|
|
* 4) Invoke the start() method to start processing.
|
|
* 5) Invoke the stop() method to stop processing.
|
|
*
|
|
* Optional: if you want to reuse the processing chain with a new sample source,
|
|
* invoke the following method sequence: stop(), setSource(), start()
