public class AnchorConverter
extends Object
A helper class for coverting between external and internal representation of an anchor. The idea behind it is that we want anchors and regular ids to be distinguishible and we
achive that by treating any id lower than #MIN_ANCHOR_VALUE
as regular ids, and those that are in range between #MIN_ANCHOR_VALUE
and #MAX_ANCHOR_VALUE
- as anchors. But on the storage level, we would still want to use 0-based indexation for anchors. That is why we need this conversion logic.
