Field Details

id

public final int id

Node id of the target node. Target nodes are identified via their ID, as structural changes (delete/insert) during the snapshot lead to PRE value shifts on disk. In addition, deleted/replaced nodes will not be serialized by fn:put as the identity of these nodes is gone - which is easier to track operating on IDs.
