Package org.apache.storm

Interface Summary

Interface	Description
ICredentialsListener	Allows a bolt or a spout to be informed when the credentials of the topology have changed.
ILocalCluster	This is here mostly for backwards compatibility.
ILocalCluster.ILocalTopology	Close this class to kill the topology.
ILocalClusterTrackedTopologyAware	This is here mostly for backwards compatibility.
ILocalDRPC
ISubmitterHook	if FQCN of an implementation of this class is specified by setting the config storm.topology.submission.notifier.plugin.class, that class’s notify method will be invoked when a topology is successfully submitted via StormSubmitter class.
StormSubmitter.ProgressListener	Interface use to track progress of file upload.
Testing.Condition	Simply produces a boolean to see if a specific state is true or false.

Class Summary

Class	Description
Config	Topology configs are specified as a plain old map.
Constants
DaemonConfig	Storm configs are specified as a plain old map.
ExclamationTopology	This is a basic example of a Storm topology.
ExclamationTopology.ExclamationBolt
ExclamationTopology.FixedOrderWordSpout
LocalCluster	A stand alone storm cluster that runs inside a single process.
LocalCluster.Builder	Simple way to configure a LocalCluster to meet your needs.
LocalDRPC	A Local way to test DRPC.
LogWriter	Launch a sub process and write files out to logs.
ProcessSimulator	In local mode, ProcessSimulator keeps track of Shutdownable objects in place of actual processes (in cluster mode).
ServerConstants
StormSubmitter	Use this class to submit topologies to run on the Storm cluster.
StormTimer	The timer defined in this file is very similar to java.util.Timer, except it integrates with Storm’s time simulation capabilities.
StormTimer.QueueEntry
StormTimer.StormTimerTask
Testing	A utility that helps with testing topologies, Bolts and Spouts.
Testing.CapturedTopology<T>	A topology that has all messages captured and can be read later on.
