Quick usage

Version version = Version.from("1.2.3");
Range range = Range.from("^1.2.0");
range.test(version) // true

Full Usage

Version comparison

boolean loose = false;
Version v1 = Version.from("1.2.3", loose);
String v2 = Version.from("1.3.0", loose);
v1.compareTo(v2); // -1
v2.compareTo(v1); // +1
v1.compareTo(v1); // 0

In Range tests

boolean loose = false;
Version v = Version.from("1.2.3", loose);
Range r = Range.from("^1.0.0", loose);
r.test(v); // true

Range boundaries test

boolean loose = false;
SemVer.isGreaterThenRange("1.3.0", ">1.0.0 <1.4.0", loose); // false
SemVer.isGreaterThenRange("1.5.0", ">1.0.0 <1.4.0", loose); // true
SemVer.isGreaterThenRange("0.9.0", ">1.0.0 <1.4.0", loose); // false
SemVer.isLessThenRange("1.3.0", ">1.0.0 <1.4.0", loose); // false
SemVer.isLessThenRange("1.5.0", ">1.0.0 <1.4.0", loose); // false
SemVer.isLessThenRange("0.9.0", ">1.0.0 <1.4.0", loose); // true

Sorting

List<Version> versions = new ArrayList<Version>();
versions.add(Version.from("4.2.0", false));
versions.add(Version.from("1.8.0", false));
versions.add(Version.from("1.2.0", false));
versions.sort(new VersionComparator()); // { "4.2.0", "1.8.0", "1.2.0" }

Versions Stream filtering

List<Version> versions = new ArrayList<Version>();
versions.add(Version.from("4.2.0", false));
versions.add(Version.from("1.8.0", false));
versions.add(Version.from("1.2.0", false));
Range range = Range.from(">3.0.0", false);
version.stream().filter(range::test); // { "4.2.0" }

$ trash build
$ trash tmp
