Class VersionNumber

java.lang.Object

org.gradle.playframework.util.VersionNumber

All Implemented Interfaces:

Comparable<VersionNumber>

public class VersionNumber
extends Object
implements Comparable<VersionNumber>

Represents, parses, and compares version numbers. Supports a couple of different schemes:

• MAJOR.MINOR.MICRO-QUALIFIER (the default).
• MAJOR.MINOR.MICRO.PATCH-QUALIFIER.

The parse(java.lang.String) method handles missing parts and allows "." to be used instead of "-", and "_" to be used instead of "." for the patch number.

This class considers missing parts to be 0, so that "1.0" == "1.0.0" == "1.0.0_0".

Note that this class considers "1.2.3-something" less than "1.2.3". Qualifiers are compared lexicographically ("1.2.3-alpha" < "1.2.3-beta") and case-insensitive ("1.2.3-alpha" < "1.2.3.RELEASE").

To check if a version number is at least "1.2.3", disregarding a potential qualifier like "beta", use version.getBaseVersion().compareTo(VersionNumber.parse("1.2.3")) >= 0.
