Syntax
class FRepChangelistState : public FNoncopyable
Remarks
Stores changelist history (that are used to know what properties have changed) for objects.
Only a fixed number of history items are kept. Once that limit is reached, old entries are merged into a single monolithic changelist (this happens incrementally each time a new entry is added).
