Class MesosNativeLibrary.Version

java.lang.Object

org.apache.mesos.MesosNativeLibrary.Version

All Implemented Interfaces:

java.lang.Comparable<MesosNativeLibrary.Version>

Enclosing class:

MesosNativeLibrary

public static class MesosNativeLibrary.Version
extends java.lang.Object
implements java.lang.Comparable<MesosNativeLibrary.Version>

Represent a 'libmesos' version with Major, Minor, and Patch versions. We use a class here to make it easier to do version compatibility checking. For example:

 
 static Version BugFixVersion = new Version(0, 22, 1);
 public static void myFunction() {
   if (version().compareTo(BugFixVersion) >= 0) {
     // New behavior with bug fix.
   } else {
     // Old behavior for backwards compatibility.
   }
 }
