3.1.9.7. RevisionVersion¶

class PyDvi.Tools.RevisionVersion.RevisionVersion(version)[source]¶

Bases: object

This class implements a revision version of the form vx.y.z where x, y and z are the major, minor and revision number, respectively.

To compare two version, the version x.y.z is converted to an integer using the following formulae: (x * scale + y) * scale + z. Thus x, y and z must be less than the scale.

version

could be a version string or a sequence of three integers.

Examples:

RevisionVersion('v0.1.2')
RevisionVersion((0,1,2))
RevisionVersion([0,1,2])

Two Instances can be compared using operator: ==, <, >, <=, >=.

An instance can be formated using str() function.
