linkedOffsetCallback property
Callback that is called to compute the linked offset of the follower layer
based on the leaderOffset
of the leader layer.
This is like FollowerLayer.linkedOffset but as a callback. Note that this has the exact function of FollowerLayer.linkedOffset and therefore the leader layer offset does not need to be added to the returned offset. The returned offset should only be the offset from the leader layer.
Implementation
Offset Function() linkedOffsetCallback;
