All Implemented Interfaces:

java.io.Serializable, Span, Span1D, TextSpan

public class FakeTextSpan

extends java.lang.Object

implements TextSpan, java.io.Serializable

An object that behaves like a text span but is not stored in a real Storm block. Used for things like coordinates or other computer-generated rapidly changing content. Must be atomic: if you give one piece away, you give the whole thing away. Must be short, because the whole thing is repeated whereever one piece goes. See PEG miniblocks--benja.
