Re: [aspectj-users] Adding common methods for Enum

[Simone Gianni <simoneg@xxxxxxxxxx>]

Hi Vinodh,
Unfortunately no, you cannot use AspectJ to inject methods in Enums, as
is explained in AspectJ 5 manual at chapter 7. You can fill a request
for an enhancement, or look if there is already one open and vote for
it, in both cases adding your use case.

Anyway, I'm pretty sure there is already a method called valueOf() that
will convert the textual (String) name of an Enum to its corresponding
constant.
