Hi

I have been wondering about creating a unit with classes representing normal variable types, like a TIntegerObj, TCharacterObj, etc. The idea comes from Java, and I have found some occations when this would have been very helpful.

Basically I have two question about this: Is there something similar already in the FCL?
And, what is the performance issues in FP about creating new objects? (example:, what kind of performance issues would there be when you create and work with a TObjectList with loads of TIntegerObj instances, instead of a normal TList containing integer pointers)

Peace.

No.

There would be a serious slowdown, as each object must be allocated on the heap. If you want to do such a thing, I suggest you write a separate heapmanager, which does some optimization for small blocks.
