@SuppressWarnings({"RawUseOfParameterizedType"})
class DataflowSelectorActor
extends DataflowProcessorActor

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

Iteratively waits for values on the inputs. Once all a value is available (received as a message), the selector's body is run.
