hi,

do you know if https://docwiki.embarcadero.com/Libraries/Sydney/en/System.Generics.Collections.TDictionary.Remove

remove method will dispose an inserted record automatically?

The TObjectDictionary supports ownerships

I was wondering about use a record instead of a class or a object

if add will call a mem place for the record

of maybe if we should use New and Dispose on remove

probably is better stay with a basic class creation and disposal

 

the doc is unclear, if remove dispose the loaded struct or should be done manually

Records are value types, so adding a record to a TDictionary<recordtype> adds a copy of the record to the internal storage, and Remove then clears up that copies memory. So there are no leaks, but adding a record and getting it back later always makes a full copy of the record, which can be a bit hard on performance.

Are you holding records or pointers to records? Because the question only makes sense if the latter. If the latter then something needs to allocate and deallocate. But i suspect that you are doing the former.
