water

Class UniqueFrameId

java.lang.Object

water.Iced

water.UniqueId

water.UniqueFrameId

All Implemented Interfaces:

java.lang.Cloneable, Freezable

public final class UniqueFrameId
extends UniqueId

Frames are mutable, so we can't create a unique id at creation time to distinguish between Frames. In addition, we'll want to know that two Frames parsed from the same data are equivalent. Therefore, we store the Frame here, and generate a good hash of the contents of the Vecs when we are asked for the id.
