Examples of TopologyContext

backtype.storm.task.TopologyContext
A TopologyContext is given to bolts and spouts in their "prepare" and "open" methods, respectively. This object provides information about the component's place within the topology, such as task ids, inputs and outputs, etc.
The TopologyContext is also used to declare ISubscribedState objects to synchronize state with StateSpouts this object is subscribed to.

Examples of backtype.storm.task.TopologyContext

    Tuple normalTuple = mockNormalTuple(new Object());
    Tuple tickTuple = MockTupleHelpers.mockTickTuple();


    RollingCountBolt bolt = new RollingCountBolt();
    Map conf = mock(Map.class);
    TopologyContext context = mock(TopologyContext.class);
    OutputCollector collector = mock(OutputCollector.class);
    bolt.prepare(conf, context, collector);


    // when
    bolt.execute(normalTuple);
