Hi Jonathan,
interesting : this snippet compiles.
interface IBindingList {
@property bool AllowEdit();
class A : IBindingList {
private bool _allowEdit;
@property {
bool AllowEdit() { return _allowEdit; }
bool AllowEdit(bool enable) { return _allowEdit = enable; }
}
}
But this one NOT.
interface IBindingList {
@property bool AllowEdit();
@property bool AllowEdit(bool enable);
}
class A : IBindingList {
private bool _allowEdit;
@property {
bool AllowEdit() { return _allowEdit; }
}
}
IMO this is bad design.
