Class AbstractGremlinPlugin

java.lang.Object

org.apache.tinkerpop.gremlin.groovy.plugin.AbstractGremlinPlugin

All Implemented Interfaces:

GremlinPlugin

Direct Known Subclasses:

CredentialGraphGremlinPlugin, GiraphGremlinPlugin, HadoopGremlinPlugin, Neo4jGremlinPlugin, SparkGremlinPlugin, SugarGremlinPlugin, TinkerGraphGremlinPlugin

Deprecated.

As of release 3.2.4, replaced by AbstractGremlinPlugin.

@Deprecated
public abstract class AbstractGremlinPlugin
extends Object
implements GremlinPlugin

A base class for a plugin that provides access to the shell and io variables. This is a good class to extend from if the plugin needs to interact with the shell in some way, such as the case with those plugins that want to utilize the RemoteAcceptor and may need access to those shell and io objects.

Constructor Summary

Constructors

Constructor and Description
AbstractGremlinPlugin() Deprecated. Creates a new instance that does not force the plugin to require the console.
AbstractGremlinPlugin(boolean requireConsoleEnvironment) Deprecated. Creates a new instance that allows the plugin to specify whether the console is required or not.

Method Summary

Modifier and Type	Method and Description
abstract void	afterPluginTo(PluginAcceptor pluginAcceptor) Deprecated. Called after the pluginTo(PluginAcceptor) method is executed which sets the io and shell member variables.
void	pluginTo(PluginAcceptor pluginAcceptor) Deprecated. Implementers will typically execute imports of classes within their project that they want available in the console or they may use meta programming to introduce new extensions to the Gremlin.

Constructor Detail

AbstractGremlinPlugin

public AbstractGremlinPlugin()

Deprecated.

Creates a new instance that does not force the plugin to require the console. This will create a plugin that will work in Gremlin Console and Gremlin Server.

AbstractGremlinPlugin

public AbstractGremlinPlugin(boolean requireConsoleEnvironment)

Deprecated.

Creates a new instance that allows the plugin to specify whether the console is required or not. It is only necessary to require the console if there are specific required calls to IO or to Groovysh methods in the plugin (as those classes are Gremlin Console related and cannot be provided outside of that environment). For a plugin to work in the Gremlin Console and in Gremlin Server this value must be set to false.

Method Detail

pluginTo

public void pluginTo(PluginAcceptor pluginAcceptor)
              throws IllegalEnvironmentException,
                     PluginInitializationException

Deprecated.

Implementers will typically execute imports of classes within their project that they want available in the console or they may use meta programming to introduce new extensions to the Gremlin.

Provides a base implementation for plugins by grabbing the console environment variables and assigning them to the io and shell member variables.

Specified by:

pluginTo in interface GremlinPlugin

Throws:

IllegalEnvironmentException - if requireConsoleEnvironment is set to true and if either the io and shell member variables are null.

PluginInitializationException - if there is a failure in the plugin iniitalization process

afterPluginTo

public abstract void afterPluginTo(PluginAcceptor pluginAcceptor)
                            throws IllegalEnvironmentException,
                                   PluginInitializationException

Deprecated.

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

Throws:

IllegalEnvironmentException

PluginInitializationException
