How to declare a const const-pointer? [message #1808928]

Hi all,

I just stumbled over the (admittedly somewhat academic) topic of how does one declare a const pointer to a (non-)const type for C/C++, i.e. something like

char const* foo;

(Again, note that here the pointer is const, but not the data pointed to.) When generating code, I always end up with

const char* foo;

regardless of the order of the <Ptr>- and <Const>-stereotypes applied.

Regards,

Martin Friedrich

Dear Martin,

the code generator does not properly support this case - it does not take the order of the stereotype application into account. If you think that this is an important limitation, please post a bug.
A (quite ugly) is not to apply the <Const> stereotype and use the "declaration" attribute of the <Ptr> stereotype, i.e. assign the string "const*".

Hi Ansgar,

thanks for your fast reply and the proposed workaround. I have sent a bug report to the papyrus-bugzilla.

I wonder if a similar issue exists for the volatile or mutable stereotypes?

Bye,

Martin
