All Classes

Class	Description
AbstractAuthenticationHandler	Provides an abstraction point to allow for http auth schemes beyond basic auth.
AbstractChannelizer	A base implementation for the Channelizer which does a basic configuration of the pipeline, one that is generally common to virtually any Gremlin Server operation (i.e.
AbstractEvalOpProcessor	A base OpProcessor implementation that helps with operations that deal with script evaluation functions.
AbstractEvalOpProcessor.BindingSupplier
AbstractOpProcessor	A base OpProcessor implementation that processes an Iterator of results in a generalized way while ensuring that graph transactions are properly managed.
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.
AbstractSession.CloseReason	The reason that a particular session closed.
AllowAllAuthenticator	Allows all requests to be authenticated.
AuthenticatedUser
AuthenticationException	An exception that occurs when during authentication such as a failed login.
Authenticator	Provides methods related to authentication of a request.
Authenticator.SaslNegotiator	Performs the actual SASL negotiation for a single authentication attempt.
AuthorizationException	An exception that occurs during authorization, i.e.
Authorizer	Provides the interface for authorizing a user per request.
Channelizer	An interface that makes it possible to plugin different Netty pipelines to Gremlin Server, enabling the use of different protocols, mapper security and other such functions.
CheckedGraphManager	A GraphManager that will prevent Gremlin Server from starting if all configured graphs fail.
Context	The context of Gremlin Server within which a particular request is made.
Context.RequestContentType	The type of the request as determined by the contents of Tokens.ARGS_GREMLIN.
DefaultGraphManager	Holder for Graph and TraversalSource instances configured for the server to be passed to script engine bindings.
DefaultTemporaryException	This is a default TemporaryException implementation that server implementers could use if they wished to indicate retry operations to the client.
ExceptionHelper	Deprecated. As of release 3.5.3, replaced by ExceptionHelper in gremlin-core
Frame	A holder for a String or ByteBuf that represents a message to be written back to the requesting client.
GraphManager	The GraphManager interface allows for reference tracking of Graph references through a Map<String, Graph>; the interface plugs into the lifeline of gremlin script executions, meaning that commit() and rollback() will be called on all graphs stored in the graph reference tracker at the end of the script executions; you may want to implement this interface if you want to define a custom graph instantiation/closing mechanism; note that the interface also defines similar features for TraversalSource objects.
GremlinResponseFrameEncoder	Ensures that any ResponseMessage manages to get converted to a Frame.
GremlinServer	Start and stop Gremlin Server.
GremlinServerGremlinPlugin	A GremlinPlugin implementation that adds Gremlin Server specific classes to the imports.
GremlinServerInstall	Command line installer for plugins to Gremlin Server.
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.
HttpChannelizer	Constructs a Channelizer that exposes an HTTP endpoint in Gremlin Server.
HttpGremlinEndpointHandler	Handler that processes HTTP requests to the HTTP Gremlin endpoint.
HttpHandlerUtil	Provides methods shared by the HTTP handlers.
HttpUserAgentHandler
JaasKrbUtil	JAAS utilities for Kerberos login.
JaasKrbUtil.KrbCallbackHandler
Krb5Authenticator	A Kerberos (GSSAPI) implementation of an Authenticator This authenticator authenticates and autorizes all clients with a valid service ticket.
LifeCycleHook	Provides a method in which users can hook into the startup and shutdown lifecycle of Gremlin Server.
LifeCycleHook.Context	Contains objects from the server that might be useful to scripting during the startup and shutdown process.
MetricManager	Singleton that contains and configures Gremlin Server's MetricRegistry.
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
OpLoader	Uses ServiceLoader to load OpProcessor instances into a cache.
OpProcessor	Interface for providing commands that websocket requests will respond to.
OpProcessorException
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.
ServerGremlinExecutor	The core of script execution in Gremlin Server.
Session	Requests that arrive through the UnifiedHandler are all processed within a Session implementation.
Session	Defines a "session" for the SessionOpProcessor which preserves state between requests made to Gremlin Server.
SessionException	An exception that holds the error-related ResponseMessage which is meant to be returned to the calling client.
SessionOpProcessor	Simple OpProcessor implementation that handles ScriptEngine script evaluation in the context of a session.
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.
Settings	Server settings as configured by a YAML file.
Settings.AuthenticationSettings	Settings for the Authenticator implementation.
Settings.AuthorizationSettings	Settings for the Authenticator implementation.
Settings.BaseMetrics
Settings.ConsoleReporterMetrics	Settings for a Metrics reporter that writes to the console.

Settings.GraphiteReporterMetrics	Settings for a Metrics reporter that writes to Graphite.
Settings.HostPortIntervalMetrics
Settings.IntervalMetrics
Settings.JmxReporterMetrics	Settings for a Metrics reporter that writes to JMX.
Settings.ProcessorSettings	Custom configurations for any OpProcessor implementations.
Settings.ScriptEngineSettings	Settings for the ScriptEngine.
Settings.SerializerSettings	Settings for the MessageSerializer implementations.
Settings.ServerMetrics	Settings for Metrics recorded by Gremlin Server.
Settings.Slf4jReporterMetrics	Settings for a Metrics reporter that writes to the SL4J output.
Settings.SslSettings	Settings to configure SSL support.
SimpleAuthenticator	A simple implementation of an Authenticator that uses a Graph instance as a credential store.
SingleTaskSession	A simple Session implementation that accepts one request, processes it and exits.
StandardOpProcessor	Simple OpProcessor implementation that handles ScriptEngine script evaluation outside the context of a session.
StateKey	Keys used in the various handlers to store state in the pipeline.
TextPlainMessageSerializer	A highly use-case specific serializer that only has context for HTTP where results simply need to be converted to string in a line by line fashion for text based returns.
ThreadFactoryUtil
TraversalOpProcessor	Simple OpProcessor implementation that iterates remotely submitted serialized Traversal objects.
