Sorry to double post, but below is the word from the ES4 guys. Looks like nullable primitive types are in the new spec. Hopefully Adobe will follow suit: ------------------------------------------- > Just for clairification... These wrapper classes will be available in > the NEXT version of es4?
There is only one version of ES4 (after that it will be ES5...) ActionScript 3 serves as a basis for ES4 but ES4 is not quite compatible with AS3. The ES4 design docs on the wiki do not always explain the current state of the language; we're not updating them any more. (Tentatively the ES4 spec will be complete next year.) --lars > -----Original Message----- > Subject: Re: Proposal: nullable wrapper class for primitive data types > (int, Number, Boolean) > > Those pages are probably somewhat out of date. > > At present we have Boolean, Number, and String which are nullable > wrapper classes for boolean, double, and string, respectively.
