Examples of opennlp.tools.util.Version

opennlp.tools.util.Version
The {@link Version} class represents the OpenNlp Tools library version.
The version has three parts:
- Major: OpenNlp Tools libraries with a different major version are not interchangeable.
- Minor: OpenNlp Tools libraries with an identical major version, but different minor version may be interchangeable. See release notes for further details.
- Revision: OpenNlp Tools libraries with same major and minor version, but a different revision, are fully interchangeable.
