I need to pass a function as a parameter like this:
procedure SomeProc(AParameter: TFunc<Integer, Integer>);
When I have this function...
function DoSomething(AInput: Integer): Integer;
...
SomeProc(DoSomething);
...
...the Delphi programming code works. But with parameter modifications like const
, var
, or default values like...
function DoSomething(const AInput: Integer = 0): Integer;
...compiler returns an error of mismatch parameter list.
Is there any way to pass parameter modificators, or avoid this error?
Many thanks for your suggestions.

No. The function you supply to SomeProc
must have a signature that matches TFunc<Integer, Integer>
.
