public final class View
extends _View

The view represents a type of branching mechanism for versioned data. Versions assigned to views are valid only in the context of the view (or in its downstream views, provided there have been no versions assigned to them). Once assigned to a View, the version becomes view-dependent; and all future versions must also be assigned to views. A version participating in a view can be "branched" into any downstream (child) views, but can not be branched into any of its parent views.

Use the newView static factory method(s), not the View 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
