Subject: Novice Question on Record Representation
Date: 16 Dec 92 22:57:12 GMT [thread overview]
Message-ID: <1992Dec16.225712.23791@saifr00.cfsat.honeywell.com> (raw)
There is a type in another package I need to use in a record in my package.
Unfortunately, that type is private and I need to use record representation
for my record.
package Some_Package is
type Some_Int is new integer;
for Some_Int'size use 16;
type Some_Type is private
-- etc etc
private
type Some_Type is new integer;
for Some_Type'size use 32;
end Some_Package;
with Some_Package;
package My_Package is
type My_Rec (Choice: Boolean := True) is record
case Choice is
when True =>
A : Some_Package.Some_Int;
B : Some_Package.Some_Int;
C : Some_Package.Some_Type;
when False =>
D : Some_Package.Some_Int;
end case;
end record;
for My_Rec use record
A at 0 range 0..15;
B at 0 range 16..31;
C at 1 range 0..31; -- of course there is an error here!
Choice at 2 range 0..31;
D at 0 range 0..15;
end record;
-- etc etc
end My_Package;
I know that I cannot do the above cos C is of Some_Package.Some_Type which
is a private type.
So, other than yelling at the person and getting him to change his type
to public, what are my alternatives given that I need to use record
representation. Please also let me know some pros and cons (if any) to any
alternative.
Thanks in advance!
