module Origen::CoreCallbacks
The regular callbacks module will register listeners that expire upon the next target load, normally this is what is wanted at app level since things should start afresh every time the target is loaded.
However within Origen
core (and possibly some plugins) it is often the case that registered listeners will be objects that are not re-instantiated upon target load and persist for the entire Origen
thread. In this case use the PersistentCallbacks
module instead of the regular Callbacks
module to make these objects register as permanent listeners.
