Which FPC version? Which language mode?
{$mode Delphi}
I've just tried {$mode objfpc} and compiles type declaration, (Delphi
mode can't understand generics?)
Mode Delphi follows Delphi's syntax, thus no "generic" and "specialize"
keywords.
But now I have another problem, when I use the variable, I get "Argument
can't be assigned to"
var
arrayAlias:TArrayAlias;
aliasList:TStringList;
...
begin
...
arrayAlias[i].AliasName:=aliasList[i]; //<==== Error here
Where TArrayAlias=TArray<TRegAlias>, and TArray<_T> is an object, not a
class.
And it has a property
property item[index:Integer]:_T read getItem write setItem; default;
So, it has the getter and the setter.
Doesn't objfpc mode accept default indexed properties?
The problem isn't default indexed properties. I guess your TRegAlias is
a record, thus it will be victim of this:
