Class Version

java.lang.Object
com.hazelcast.version.Version
All Implemented Interfaces:
DataSerializable, IdentifiedDataSerializable, Comparable<Version>
public final class Version extends Object implements IdentifiedDataSerializable, Comparable<Version>
A generic version to be used with VersionAware classes. The version is composed of two bytes, denoting MAJOR.MINOR version. It is used to represent the Hazelcast cluster version and the serialization version of VersionAware classes.
Since:
3.8

    • UNKNOWN_VERSION

      public static final byte UNKNOWN_VERSION
      Use 0 as major & minor values for UNKNOWN version

    • UNKNOWN

      public static final Version UNKNOWN
      Version 0.0 is UNKNOWN constant
      • UNKNOWN is only equal to itself.
      • is(Less|Greater)Than method with an UNKNOWN operand returns false.
      • is(Less|Greater)OrEqual with an UNKNOWN operand returns false, unless both operands are UNKNOWN.
      • UNKNOWN.isUnknown(Less|Greater)(Than|OrEqual) returns true.
      • otherVersion.isUnknown(Less|Greater)(Than|OrEqual) with an UNKNOWN argument returns false.
