However it would be nice to have a feature like
property Foo[Index: Integer]: Integer write SetFoo read GetFoo;
property Foo[Index: Integer; Ask: Boolean]: Integer write
SetFooAsk read GetFooAsk;
The must have different Method Names, because the Setters(write
SetFoo) last argument is the Value, so it' can not have a optional
Ask element:
procedure WrongSetFoo(Index: Integer; Ask: Boolean= True; AValue:
Integer);
But with different Setter/Getters that would not be a problem. In
fact they can have the same name, if they are overloaded.
Any idea if such a feature would have a chance?
It won't: http://bugs.freepascal.org/view.php?id=12737 (that
feature request was about having getters/setters with the same
name, but the core problem is having multiple properties with the
same name).
As far as I know, delphi 2005 and up allow the problem in 12737 for
non-published properties.
Since array properties cannot be published anyway, the argument with
RTTI is void ?
(which doesn't mean there are no other arguments to prevent it's
implementation)
Other arguments are also mentioned in the bug report (including about
only allowing it for non-published properties). The fact that Delphi
allows it is obviously a strong argument in favour of allowing it
anyway.
