public final class DynamicDeltaInt extends Object implements CSProcess
This process broadcasts integers arriving on its input channel in parallel to its output channel array -- those output channels can be changed dynamically.Process Diagram
Description
A DynamicDeltaInt 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 DynamicDeltaInt a channel on which it will be listening. A process may leave the broadcast be re-sending that same channel.In each cycle, DynamicDeltaInt 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 ChannelOutputInt channels -- anything else is discarded. If the delivered ChannelOutputInt channel is not one of the channels already in the output array, it is added -- otherwise it is removed.
Channel Protocols
Input Channels in int All channels in this package carry integers. config java.lang.ChannelOutputInt All channels in this package carry integers -- except for this one, which accepts only ChannelOutputInt
objects (discarding all others).Output Channels out[] int The output Channels will carry a broadcast of whatever integers are sent down the in Channel. - Author:

DynamicDeltaInt
public DynamicDeltaInt(AltingChannelInputInt in, AltingChannelInput config)
Construct a new DynamicDeltaInt process with the input channel in and the configuration channel configure.- Parameters:
in
- the input Channelconfig
- the configuration channel
-
DynamicDeltaInt
public DynamicDeltaInt(AltingChannelInputInt in, AltingChannelInput config, ChannelOutputInt[] out)
Construct a new DynamicDeltaInt process with the input channel in, the configuration channel configure and the initial output channels out. The ordering of the channels in the out array make no difference to the functionality of this process.- Parameters:
in
- the input channelconfig
- the configuration channelout
- the output channels
