Interface	Description
IStateSpout
IStateSpoutOutputCollector
ISubscribedState
ISynchronizeOutputCollector
KeyValueState<K,V>	A state that supports key-value mappings.
Serializer<T>	Interface to be implemented for serlializing and de-serializing the state.
State	The state of the component that is either managed by the framework (e.g in case of IStatefulBolt) or managed by the the individual components themselves.
StateEncoder<K,V,KENCODED,VENCODED>	The interface of State Encoder.
StateProvider	Used by the StateFactory to create a new state instances.

Class Summary

Class	Description
BaseBinaryStateIterator<K,V>	Base implementation of iterator over KeyValueState which encoded types of key and value are both binary type.
BaseStateIterator<K,V,KENCODED,VENCODED>	Base implementation of iterator over KeyValueState.
DefaultStateEncoder<K,V>	Default state encoder class for encoding/decoding key values.
DefaultStateSerializer<T>	A default implementation that uses Kryo to serialize and de-serialize the state.
InMemoryKeyValueState<K,V>	An in-memory implementation of the State
InMemoryKeyValueStateProvider	Provides InMemoryKeyValueState
StateFactory	A factory for creating State instances
StateSpoutOutputCollector
