org.jgroups.Version

public class Version
extends java.lang.Object

We're using the scheme described at http://www.jboss.com/index.html?module=bb&op=viewtopic&t=77231 for major, minor and micro version numbers. We have 5 bits for major and minor version numbers each and 6 bits for the micro version. This gives: X = 0-31 for major versions Y = 0-31 for minor versions Z = 0-63 for micro versions

main

public static void main(java.lang.String[] args)

Prints the value of the description and cvs fields to System.out.

Parameters:

args -

printDescription

public static java.lang.String printDescription()

Returns the catenation of the description and cvs fields.

Returns:

String with description

printVersion

public static java.lang.String printVersion()

Returns the version field as a String.

Returns:

String with version

isSame

public static boolean isSame(short v)

Compares the specified version number against the current version number.

Parameters:

v - short

Returns:

Result of == operator.

encode

public static short encode(int major,
                           int minor,
                           int micro)

Method copied from http://www.jboss.com/index.html?module=bb&op=viewtopic&t=77231

print

public static java.lang.String print(short version)

Method copied from http://www.jboss.com/index.html?module=bb&op=viewtopic&t=77231

parse

public static short parse(java.lang.String ver)

decode

public static short[] decode(short version)

isBinaryCompatible

public static boolean isBinaryCompatible(short ver)

Checks whether ver is binary compatible with the current version. The rule for binary compatibility is that the major and minor versions have to match, whereas micro versions can differ.

Parameters:

ver -

Returns:

isBinaryCompatible

public static boolean isBinaryCompatible(short ver1,
                                         short ver2)
