Class SplitFrame

java.lang.Object

water.Iced

hex.Transformer<SplitFrame.Frames>

hex.SplitFrame

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, Freezable

public class SplitFrame
extends Transformer<SplitFrame.Frames>

Split given frame based on given ratio. If single number is given then it splits a given frame into two frames (FIXME: will throw exception) if N ratios are given then then N-splits are produced.
