org.apache.tinkerpop.gremlin.jsr223.LazyBindingsCustomizer

All Implemented Interfaces:

BindingsCustomizer, Customizer

public class LazyBindingsCustomizer
extends Object
implements BindingsCustomizer

A customizer implementation that provides bindings to a GremlinScriptEngine. If this customizer is applied directly to a GremlinScriptEngine it will not apply GLOBAL_SCOPE bindings. Those can only be applied if the customizer is applied via the GremlinScriptEngineManager (which would do so through the BindingsGremlinPlugin.
