## Class IntervalSet<T extends java.lang.Comparable<T>>

- java.lang.Object
- - org.apache.cassandra.db.commitlog.IntervalSet<T>

-     public class IntervalSet<T extends java.lang.Comparable<T>>
      extends java.lang.Object

  An immutable set of closed intervals, stored in normalized form (i.e. where overlapping intervals are converted to a single interval covering both). The set is stored as a sorted map from interval starts to the corresponding end. The map satisfies `curr().getKey() <= curr().getValue() < next().getKey()`
