Package org.apache.tinkerpop.gremlin.server.handler

Interface Summary

Interface	Description
Session	Requests that arrive through the UnifiedHandler are all processed within a Session implementation.

Class Summary

Class	Description
AbstractAuthenticationHandler	Provides an abstraction point to allow for http auth schemes beyond basic auth.
AbstractSession	A base implementation of Session which offers some common functionality that matches typical Gremlin Server request response expectations for script, bytecode and graph operations.
Frame	A holder for a String or ByteBuf that represents a message to be written back to the requesting client.
GremlinResponseFrameEncoder	Ensures that any ResponseMessage manages to get converted to a Frame.
HttpBasicAuthenticationHandler	Implements basic HTTP authentication for use with the HttpGremlinEndpointHandler and HTTP based API calls.
HttpBasicAuthorizationHandler	An authorization handler for the http channel that allows the Authorizer to be plugged into it.
HttpGremlinEndpointHandler	Handler that processes HTTP requests to the HTTP Gremlin endpoint.
HttpHandlerUtil	Provides methods shared by the HTTP handlers.
MultiTaskSession	A Session implementation that queues tasks given to it and executes them in a serial fashion within the same thread which thus allows multiple tasks to be executed in the same transaction.
OpExecutorHandler
OpSelectorHandler
SaslAndHttpBasicAuthenticationHandler	An Authentication Handler for doing WebSocket Sasl and Http Basic auth
SaslAuthenticationHandler	A SASL authentication handler that allows the Authenticator to be plugged into it.
SessionTask	A SessionTask equates to a particular incoming request to the UnifiedHandler and is analogous to a Context in the OpProcessor approach to handling requests to the server.
SingleTaskSession	A simple Session implementation that accepts one request, processes it and exits.
StateKey	Keys used in the various handlers to store state in the pipeline.
UnifiedHandler	Handler for websockets to be used with the UnifiedChannelizer.
WebSocketAuthorizationHandler	An authorization handler for the websockets channel that allows the Authorizer to be plugged into it.
WsAndHttpChannelizerHandler	A ChannelInboundHandlerAdapter for use with WsAndHttpChannelizer that toggles between WebSockets and http.
WsGremlinBinaryRequestDecoder	Decodes the contents of a BinaryWebSocketFrame.
WsGremlinCloseRequestDecoder	Handles close requests over web sockets.
WsGremlinResponseFrameEncoder	Encodes ByteBuf and String values to Websocket frames.
WsGremlinTextRequestDecoder	Decodes the contents of a TextWebSocketFrame.

Enum Summary

Enum	Description
AbstractSession.CloseReason	The reason that a particular session closed.

Exception Summary

Exception	Description
SessionException	An exception that holds the error-related ResponseMessage which is meant to be returned to the calling client.
