The Wiert Corner - irregular stream of stuff: jpluimers

There is an interesting G+ discussion thread about generic Dictionaries in Delphi.

It covers the stock TObjectDictionary in the Generic.Collections unit, Spring4D, performance characteristics like O(1), O(log n), etc, and implementation details like fill factors and hashing algorithms.

Worth reading at Steve Maughan – Google+ – TObjectDictionary Advice Needed I’ve been using Delphi for….

Since TObjectDictionary hasn’t changed much since the introduction of generics in Delphi, this discussion is valid for at least Delphi XE and up (and probably Delphi 2010 and 2009 as well).

I’m not sure about these last ones as like Andreas Hausladen, I’m cutting back on the Delphi versions I regularly use, which for now are mainly XE6, XE3, XE and 2007).
