Syntax

bool ConditionalCreateNewDeltaState
(
const TMap< int32, int32 > & OldIDToKeyMap,
const int32 BaseReplicationKey
)

Remarks

Checks to see if the ArrayReplicationKey has changed, and if so creates a new DeltaState that is passed out to the caller. Note, this state may just be a copy of a previous state, or a brand new state.

Returns

True if the keys were different and a state was created. False if the keys were the same, and we can skip serialization.
