public final class Version extends Object implements IdentifiedDataSerializable, Comparable<Version>
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.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.

UNKNOWN_VERSION
Use 0 as major & minor values for UNKNOWN version
