TFPGList<> requires an = operator for the type you want to specialize with.
While you could declare a global operator overload for TTestObject this
won't help as it needs to be a local one. Only records with modeswitch
advancedrecords support this currently, thus you should adjust your code
like this:
=== code begin ===
{$modeswitch advancedrecords} // this needs to be after the $mode, but
before the uses section
type
TTestObject = record
i: integer;
class operator = (const aLeft, aRight: TTestObject): Boolean;
end;
TTestObjectList = specialize TFPGList<TTestObject>;
// ...
class operator TTestObject.=(const aLeft, aRight: TTestObject): Boolean;
begin
// whatever you need for equality
end;
=== code end ===
