I'd like to have a generic objcclass that would add some extra
functionality for multiple base types. I don't have a lot of experience
with generics, but this compiles:
------
generic TMyControl<T: TWinControl> = class(T)
private
FField: string;
procedure Foo;
end;
TMyEdit = specialize TMyControl<TEdit>;
------
and this fails with the error 'Class or interface type expected, but got
"NSView"':
------
generic NSMyView<T: NSView> = objcclass(T)
private
FField: string;
procedure Foo; message 'Foo:';
end;
------
The documentation doesn't mention it, so I'm assuming it's just not
implemented. Is that something that could be supported? Would it be
difficult to do so? Are there any existing Objective Pascal specific
tricks I could use to avoid duplicating all of the fields/code?
Thanks!
