Class SargIntervalSequence

java.lang.Object
  org.eigenbase.sarg.SargIntervalSequence

public class SargIntervalSequence
extends Object

SargIntervalSequence represents the union of a set of disjoint SargInterval instances. (If any adjacent intervals weren't disjoint, they would have been combined into one bigger one before creation of the sequence.) Intervals are maintained in coordinate order.
