The JKScriptEngineFactory Class
Listing 8-3 contains the implementation for the ScriptEngineFactory interface for the
JKScript engine. Some of its methods return a "Not Implemented" string because you do
not support features exposed by those methods. The code in the JKScriptEngineFactory
class is self-explanatory. An instance of the JKScript engine may be obtained using
ScriptEngineManager with a name of jks , JKScript , or jkscript as coded in the
getNames() method.
