Version (Hazelcast Root 5.2.1 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

Field Summary

Fields
Modifier and Type	Field and Description
`static 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.
`static byte`	`UNKNOWN_VERSION` Use 0 as major & minor values for UNKNOWN version
