compareTo

public final int compareTo(Version version)

Compares two versions objects. Note that if the major, minor, and revision are all the same, tags are compared with String.compareTo(). Having no tag is considered a newer version than a version with a tag.

Specified by:

compareTo in interface java.lang.Comparable<Version>

Parameters:

version - The version to compare this version to

Returns:

0 if the version is equal to this version, 1 if the version is greater than this version, or -1 if the version is lower than this version.

Parameters:

version - The version to compare this version to

noTagsAreNewer - Whether versions with no tag are considered newer than those that have tags

Returns:

0 if the version is equal to this version, 1 if the version is greater than this version, or -1 if the version is lower than this version.
