Class VersionReference

java.lang.Object
  wt.vc.VersionReference

All Implemented Interfaces:

Externalizable, Serializable, NetFactor, ObjectMappable, WTReference

public class VersionReference
extends Object
implements WTReference, Externalizable

The VersionReference is a kind of reference to Iterated objects by means of the overridden key. This key is a foreign key to the latest iteration in a branch.

Use the newVersionReference static factory method(s), not the VersionReference constructor, to construct instances of this class. Instances must be constructed using the static factory(s), in order to ensure proper initialization of the instance.

Supported API: true

Extendable: false
