Class VersionRange<Version extends Comparable<Version>>

java.lang.Object
io.strimzi.api.annotations.VersionRange<Version>
Type Parameters:
Version - The type of the version. This class assumes that older versions are less than newer versions and Comparable.compareTo(Object) is consistent with Object.equals(Object).
public class VersionRange<Version extends Comparable<Version>> extends Object
Represents a range over some comparable version type. Ranges can:
  1. be Empty
  2. consist of a single version
  3. consist of an inclusive lower bound and no upper bound
  4. consist of inclusive lower and upper bounds
It is possible to test inclusion of a given version in a version range and whether two version ranges possibly intersect.
