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

        TailSpout spout = new TailSpout(spf, statusFile, tempDir, inPattern);
        spout.setReliableMode(true);


        // open spout
        Config conf = new Config();
        TopologyContext context = null;
        TestSpoutOutputCollector collector = new TestSpoutOutputCollector();
        spout.open(conf, context, collector);
        
        // add some files
        FileUtils.writeByteArrayToFile(new File(tempDir, "x-1"), payload("x-1"), true);
