Class ScriptEngineOptions

  • public class ScriptEngineOptions
extends com.ibm.jscript.JSContext
    This class configures the IBM JS script engine. Since 2.2 The isDebugAllowed is now final static so setDebugAllowed were removed to comply with the new JSContext interface. Since 2.0 ScriptEngineOptions is no longer just an options class. It also provides the isDebugAllowed() method that is different for each instance of the engine. Although this could be a static hastable with reference to the current thread, the overhead of allocating a new JSContext is fairly small since we don't use the script caching features of the JSContext.
