Same here, you're missing a type parameter. TFoo needs 2 type parameters.
Ups, thanks.
Any obvious (or non obvious) mistake of mine in the below?
Because either of the 2 commented specialize cause errors in the
generics... (but only if TFoo.F SWAPS the order of param).
It compiles fine
- with both the specialize commented
- or with TBar replacing "F" with the commented "F"
program Project1;
{$Mode objfpc}
type
generic TBar<A,B> = class; // forward // LINE 5
generic TFoo<A, B> = class
F:specialize TBar<A,B>;
X:B;
end; // LINE 10
generic TBar<A, B> = class
F:specialize TFoo<B,A>;
//F:specialize TFoo<A,B>;
X:B;
end;
//x1 = specialize TBar<Byte, Boolean>; // project1.lpr(5,28) Fatal:
Syntax error, "identifier" expected but ";" found
//x2 = specialize TFoo<Byte, Boolean>; // project1.lpr(10,6) Fatal:
Syntax error, "identifier" expected but ";" found
begin
end.
