Method Detail

getName

public String getName()

Description copied from interface: GremlinPlugin

The name of the plugin. This name should be unique (use a namespaced approach) as naming clashes will prevent proper plugin operations. Plugins developed by TinkerPop will be prefixed with "tinkerpop." For example, TinkerPop's implementation of Giraph would be named "tinkerpop.giraph". If Facebook were to do their own implementation the implementation might be called "facebook.giraph".

afterPluginTo

public void afterPluginTo(PluginAcceptor pluginAcceptor)
                   throws PluginInitializationException,
                          IllegalEnvironmentException

Description copied from class: AbstractGremlinPlugin

Called after the AbstractGremlinPlugin.pluginTo(PluginAcceptor) method is executed which sets the AbstractGremlinPlugin.io and AbstractGremlinPlugin.shell member variables.

Specified by:

afterPluginTo in class AbstractGremlinPlugin

Throws:

PluginInitializationException

IllegalEnvironmentException

requireRestart

public boolean requireRestart()

Description copied from interface: GremlinPlugin

Some plugins may require a restart of the plugin host for the classloader to pick up the features. This is typically true of plugins that rely on Class.forName() to dynamically instantiate classes from the root classloader (e.g. JDBC drivers that instantiate via @{code DriverManager}).

remoteAcceptor

public Optional<RemoteAcceptor> remoteAcceptor()

Description copied from interface: GremlinPlugin

Allows a plugin to utilize features of the :remote and :submit commands of the Gremlin Console. This method does not need to be implemented if the plugin is not meant for the Console for some reason or if it does not intend to take advantage of those commands.
