Hello,
I've spend some time adapting my beta project to use the new rtl-generics
classes, however, I have some issues regarding to TDictionary class. Let's
go to a test using the example below:
=== begin code ===
var
hash: TDictionary<string, string>;
begin
hash := TDictionary<string, string>.Create;
end
=== end code ===
You may get the following compiler log:
=== begin log ===

=== end log ===
Those hints can be a problem when we also need to check the log from other
classes, because it pollute the windows messages, so a suggestion is just
to declare the "{$WARN 5024 OFF : Parameter "$1" not used}" in the
rtl-generics units.
The question is regarding to TDictionary, because I'm not sure if it is a
concrete class on its actual implementation stage (I'm using FPC from
trunk). See the warnings below:
=== begin warns ===
generics.dictionaries.inc(158,92) Warning: Constructing a class
"TCustomDictionaryEnumerator$4$crc7DF95A99" with abstract method
"DoMoveNext"
generics.dictionaries.inc(158,92) Warning: Constructing a class
"TCustomDictionaryEnumerator$4$crc7DF95A99" with abstract method
"GetCurrent"
generics.dictionaries.inc(158,92) Warning: Constructing a class
"TCustomDictionaryEnumerator$4$crc7DF95A99" with abstract method
"DoMoveNext"
generics.dictionaries.inc(158,92) Warning: Constructing a class
"TCustomDictionaryEnumerator$4$crc7DF95A99" with abstract method
"GetCurrent"
=== end warns ===
I want to use the TDictionary in a beta project, but I'm not sure if today
it is only for experimental purposes. :-/
Thank you!
