New feature: allow spoon to do static imports for methods and fields #1040

surli · 2016-12-13T16:08:05Z

Improve ImportScannerImpl to allow Spoon to do static imports.
Change the interface of ImportScanner to return list of CtReference when doing computeImports.

Lots of tests had to be changed as with autoImports it automatically imports all static elements.

You have to clear the 3 lists

Agreed. I push the change.

monperrus · 2016-12-14T08:19:39Z

cool!

in Spoon, we aim at maximum backward compatibility and not to change the signature public methods, esp. in interfaces.

to this extent, I propose to keep computeImports as is and to introduce a new method (eg computeAllImports).

this will greatly reduce the impact in the tests (and in client code also).

(fortunately isImported(CtReference ref) is backward compatible)

wrong refactoring?

Uh. Yes, I may have done it a bit fast. Apparently I leave some occurences also in comments. I will fix that.

Ok but then DefaultJavaPrettyPrinter will use the computeAllImports, right?

In fact this one should remain the same as it's the method computeImports from DefaultJavaPrettyPrinter (not defined in any interface) which must return CtReference because it calls computeAllImports from ImportScanner.
