java.lang.Object
- io.microsphere.util.Version

All Implemented Interfaces:: java.io.Serializable, java.lang.Comparable<Version>

public class Version
extends java.lang.Object
implements java.lang.Comparable<Version>, java.io.Serializable

Represents a version number composed of major, minor, and patch components.

This class provides methods to compare versions using standard comparison operators such as greater than, less than, and equal to. It also supports parsing version strings in the format "major.minor.patch".

Example Usage


 Version v1 = new Version(1, 2, 3);
 Version v2 = Version.of("1.2.3");

 // Comparison
 boolean isEqual = v1.equals(v2); // true
 boolean isGreaterThan = v1.isGreaterThan(Version.of("1.2.2")); // true
 boolean isLessThan = v1.lt(Version.of("1.3.0")); // true

 // Parsing from string
 Version v3 = Version.of("2.0.0");

 // Getting version from a class's manifest
 Version versionFromManifest = Version.getVersion(MyClass.class);
