channels

Stores the last value received, but only made available after finish(). Once made available, clears the value.

Stores the result of applying a binary operator to the current value and each new value.

Stores the last value received, assumes that if multiple values are received, they are all equal.

Note: Unlike 'LastValue' if multiple nodes write to this channel in a single step, the values will be continuously overwritten.

A channel that switches between two states

• in the "priming" state it can't be read from.
  • if it receives a WaitForNames update, it switches to the "waiting" state.
• in the "waiting" state it collects named values until all are received.
  • once all named values are received, it can be read once, and it switches back to the "priming" state.

Stores the value received in the step immediately preceding, clears after.

A channel that waits until all named values are received before making the value available.

This ensures that if node N and node M both write to channel C, the value of C will not be updated until N and M have completed updating.

A configurable PubSub Topic.
