Hello – I’ve got an operator that runs a cleanup thread (separate from the main
event loop) and triggers a callback when an item is removed from an internal
data structure. I would like for this callback to emit data from one of the
operator’s ports, but I run into the following Exception:
(From DefaultOutputPort.java, line 58)
if (operatorThread != null && Thread.currentThread() != operatorThread) {
// only under certain modes: enforce this
throw new IllegalStateException("Current thread " +
Thread.currentThread().getName() +
" is different from the operator thread " + operatorThread.getName());
}
I could obviously extend DefaultOperatorPort to bypass this but I’d like to
understand why that constraint is there and if there’s a good way to work
around it.
Would love to hear the community’s thoughts. Thanks!
