      lime.LocalOpDescriptor
          lime.TupleOpDescriptor

All Implemented Interfaces:

class TupleOpDescriptor

extends LocalOpDescriptor

A TupleOpDescriptor will be an operation in one of the system processing vectors (namely incomingOps, incomingEvents, outgoing) that passes a tuple (either a pattern or an actual tuple). This will include operations that put tuples into the structure as well as those that request a tuple with a pattern, but will not include remote operations.
