Hello,
I have a few "hardware" types, for example uint16 and uint32. And I
want to write a functions that will set or clear bits of such types.
For example:
function Bit_Set(word: uint16; bitn: natural) return uint16;
function Bit_Set(word: uint16; bitn: natural) return uint16 is
mask: uint16 := 2**bitn;
begin
return word or mask;
end Bit_Set;
However, I realize that such a function would be almost completely
duplicated for the uint32 type. In C++ I would probably define it as a
template on the type of the word, and the compiler would do the job
for me. In Ada, however, when using generics it doesn't seem I can
leave the same function name for all types (as I would do in
overloading). I can define a generic Bit_Set, but then I have to
specialize it for uin16 and uint32 with different function names. Is
there any way I could combine the effects of generics and overloading
and get a single Bit_Set for all my types without writing the code N
times ?
P.S. Ada95
Thanks,
Eli
