Class NashornScriptEngine

  • All Implemented Interfaces:
    javax.script.Compilable, javax.script.Invocable, javax.script.ScriptEngine
    public final class NashornScriptEngine
extends javax.script.AbstractScriptEngine
implements javax.script.Compilable, javax.script.Invocable
    JSR-223 compliant script engine for Nashorn. Instances are not created directly, but rather returned through NashornScriptEngineFactory.getScriptEngine(). Note that this engine implements the Compilable and Invocable interfaces, allowing for efficient precompilation and repeated execution of scripts.
