CSProcess
This process broadcasts objects arriving on its input channel in parallel
to its output channel array -- those output channels can be changed dynamically.
Process Diagram
Description
A DynamicDelta process is a broadcasting node whose array of broadcasting channels can be changed dynamically. Any process can become one of the recipients of the broadcast by sending the DynamicDelta a channel on which it will be listening. A process may leave the broadcast be re-sending that same channel.In each cycle, DynamicDelta waits for either its in or configure channel to become ready, giving priority to configure.
Anything arriving from in is broadcast in parallel down each element of its array of out channels.
The configure channel delivers ChannelOutput channels -- anything else is discarded. If the delivered ChannelOutput channel is not one of the channels already in the output array, it is added -- otherwise it is removed.
Channel Protocols
Input Channels | ||
---|---|---|
in | java.lang.Object | The in Channel can accept data of any Class. |

The configure Channel accepts Objects of type ChannelOutput only.
