I would like to use static analysis to prevent "TypeError: Error #1009: Cannot access a property or method of a null object reference".
As far as I know there is a static analyzers for Java that use @NotNull/@Nullable. Programmer explicitly express his intentions by specifying those annotations for every member/function/argument so that tool can verify if everything is corrent and every @Nullable -> @NotNull conversion is made with a check for null. For me it would be more comfortable to only specify @Nullable so that everything else could be treated like @Nullable but it's not necessary.
I wonder if there are free tools of that kind for Actionscript 3?
I have FlashBuilder 4.5 license but beyond that I'd prefer not to purchase anything else. I heard that IntelliJ IDEA might have such a thing but it only works with Actionscript in Ultimate Edition which is not free :(
So the questions are:
- Is there such static analyzer for Actionscript 3?
- How much will it costs if it's not free?
- Is there any other solutions for preventing 1009 error except "check everything and transform your code into a mess".
