tParallelArray and interfaces

[A.M. Hoornweg 144]

Hello all,

 

just a short question: is System.Threading.tParallelarray not usable with interfaces?  The following won't compile:

 

 

Type iDownloadJob=Interface
  [{3d24b7a2-6111-46e7-a281-7fdc318be5c4}]
  procedure Download;
end;


procedure test;
var x: array of iDownloadJob; 
    temp:Integer;
begin
  // ..... fill the array here ....

 temp:=tParallelArray.ForThreshold;
 tParallelArray.ForThreshold:=1;
 try
    tParallelArray.&For<iDownloadJob>(x,
    procedure (const AValues: array of iDownloadJob; AFrom, ATo: NativeInt)
    var i:NativeInt;
    begin  
        for i:=AFrom to ATo do
            aValues[i].Download;       
    end);
 finally 
    tParallelArray.ForThreshold:=temp;
 end;      
end;

 

It would be just my luck if such a nice new feature doesn't work for me 😞 .

It compiles for me... but after adding missing quotes in interface GUID declaration. TParallelArray is not the problem here.

@A.M. Hoornweg It is always helpful to indicate what kind of error you get, and where you get it.

This is a totally weird experience.  Tuesday my compiler kept saying "There is no overloaded version of tParallelArray.For ... that can be called with these arguments" and I searched in vain for the cause.

 

Then something came up and I had to abandon the project for a few days.  Today I resumed working on it and it compiled just fine - I had changed nothing! 
I think that something got corrupted in the memory of the IDE process on Tuesday and the reboot just made it go away...  I do have regular exceptions in the IDE since installing the inline update for 12.2 (build nr 29.0.53982.0329).

 

Anyway, I'm thrilled that I can continue now.
