uk.ac.starlink.topcat.Version

All Implemented Interfaces:

Comparable<Version>

public class Version
extends Object
implements Comparable<Version>

Comparable class which can compare version strings. Versions are of the form A.B[-C[x]], where the square bracketed parts are optional. A, B and C must be integers if present. x may be freeform.

For comparison, only A, B and C parts are considered. If C is missing, it is considered equal to zero. For equality, the original version string is used.

Note: this class has a natural ordering that is inconsistent with equals.
