Method Detail

getCustomizers

public Optional<Customizer[]> getCustomizers(String scriptEngineName)

Description copied from interface: GremlinPlugin

Gets the list of Customizer implementations to assign to a new GremlinScriptEngine. The implementation should filter the returned Customizers according to the supplied name of the Gremlin-enabled ScriptEngine. By providing a filter, GremlinModule developers can have the ability to target specific ScriptEngines.

Specified by:

getCustomizers in interface GremlinPlugin

Overrides:

getCustomizers in class AbstractGremlinPlugin

Parameters:

scriptEngineName - The name of the ScriptEngine or null to get all the available Customizers

requireRestart

public boolean requireRestart()

Description copied from interface: GremlinPlugin

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