Description Scott Greer

2011-09-20 22:55:11 EDT

This is to essentially replicate RBD's handling of overloaded functions such as String.clip, for which there are two variants.    Rather than implement general-purpose support for function overloading, RBD's JS gen simply special cases these parts and these functions.  

There are a number of bugs emerging which require this support.

See SystemFunctionInvocationGenerator.java for RBD's implementation....

I have an implementation which I will commit now so that the system functions will work in JS gen, however, see this bug for the details of the eventual solution:  https://bugs.eclipse.org/bugs/show_bug.cgi?id=359315

Comment 3 Scott Greer

Fixed by implementing the following:
1.  Use existing function "aliasing" logic to handle the generation of declarations and invocations for overloaded functions
2.  Detect whether a function is overloaded by scanning a part for like-named functions.
3.  Compute a "mangled" alias for the function name that factors in the type and number of args.
