@java.lang.SuppressWarningsprivate void queryInputs(final boolean initialRun) {
class DataflowOperatorActor
extends DataflowProcessorActor

An operator's internal actor. Repeatedly polls inputs and once they're all available it performs the operator's body.

Iteratively waits for enough values from inputs. Once all required inputs are available (received as messages), the operator's body is run.
