## Class IgniteProductVersion

- java.lang.Object
- - org.apache.ignite.lang.IgniteProductVersion

- All Implemented Interfaces:
    Externalizable, Serializable, Comparable<IgniteProductVersion>

      public class IgniteProductVersion
      extends Object
      implements Comparable<IgniteProductVersion>, Externalizable

  Represents node version.

  Node version can be acquired via `ClusterNode.version()` method.

  Two versions are compared in the following order: major number, minor number, maintenance number, revision timestamp.
