Interface Summary

Interface	Description
CompleteableCommand<T>	Extension to commands that provide registration of command completion callbacks.
ConnectionFacade	Represents a stateful connection facade.
ConnectionInitializer	Initialize a connection to prepare it for usage.
DecodeBufferPolicy	Strategy defining the approach to discard bytes from the response aggregation buffer in CommandHandler.decode(ChannelHandlerContext ctx, ByteBuf buffer) to reclaim memory after various response decoding phases.
DecoratedCommand<K,V,T>	A decorated command allowing access to the underlying DecoratedCommand.getDelegate().
DemandAware	Interface for demand-aware components.
DemandAware.Sink	A demand-aware DemandAware.Sink that accepts data.
DemandAware.Source	A DemandAware.Source provides data to a DemandAware and can be notified to produce more input for the command.
Endpoint	Wraps a stateful Endpoint that abstracts the underlying channel.
ProtocolKeyword	Interface for protocol keywords providing an encoded representation.
PushHandler	A handler object that provides access to PushListener.
ReconnectionListener	Listener for reconnection events.
RedisCommand<K,V,T>	A redis command that holds an output, arguments and a state, whether it is completed or not.

Command<K,V,T>	A Redis command with a command type, arguments and an optional output.
CommandArgs<K,V>	Redis command arguments.
CommandArgsAccessor	Accessor for first encoded key, first string and first integer argument of CommandArgs.
CommandEncoder	A netty ChannelHandler responsible for encoding commands.
CommandExpiryWriter	Extension to RedisChannelWriter that expires commands.
CommandHandler	A netty ChannelHandler responsible for writing redis commands and reading responses from the server.
CommandWrapper<K,V,T>	Wrapper for a command.
ConnectionWatchdog	A netty ChannelHandler responsible for monitoring the channel and reconnecting when the connection is lost.
DecodeBufferPolicies	Utility class to construct commonly used DecodeBufferPolicy objects.
DefaultEndpoint	Default Endpoint implementation.
RedisHandshakeHandler	Handler to initialize a Redis Connection using a ConnectionInitializer.
RedisStateMachine	State machine that decodes redis server responses encoded according to the Unified Request Protocol (RESP).
TracedCommand<K,V,T>	Redis command that is aware of an associated TraceContext.
