Re-engineering source code between 1.4 and 1.5

Thread view:

Hello,

is there a tool which can help to transform java source code from/to 1.4
to/from 1.5 ? For binary 1.5 to 1.4 there is retroweaver, but is there
a source code version?

The main concern is about generics. How to automatically add/remove them.

TIA

Automatically removing them (and adding the casts where nescessary)
should be easy, but automatically adding them sounds difficult enough that I
wouldn't be surprised if no commercial tool exists to do this for you.

Hi

Have a look at Eclipse. There is a refactoring called 'Infer Generic
Type Arguments':

asks-226.htm
. Also eclipses Clean Up wizard can add some annotations for you and
convert for loops to enhanced for loops. http://www.eclipse.org/
