Version (Hazelcast Root 3.12.9 API)

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

    Constant Field Values
  - 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.
