NAME
AptPkg::Version - APT package versioning class
SYNOPSIS
use AptPkg::Version;
DESCRIPTION
The AptPkg::Version module provides an interface to
APT's package
version handling.
AptPkg::Version
The AptPkg::Version package implements the
APT pkgVersioningSystem
class.
An instance of the AptPkg::Version class may be fetched using the
"versioning" method from an AptPkg::System object.
The following methods are implemented:
- label
-
Return the description of the versioning system, for example:
Standard .deb
for Debian systems.
- compare(A, B)
-
Compare package version A with B, returning a negative value if
A is an earlier version than B, zero if the same or a positive
value if A is later.
- rel_compare(A, B)
-
Compare distribution release numbers.
- check_dep(PKG, OP, DEP)
-
Check that the package version PKG satisfies the relation OP to
the dependency version DEP.
The relation OP is specified in the Debian syntax regardless of the
versioning system:
<< strictly earlier
<= earlier or equal
= exactly equal
>= later or equal
>> strictly later
- upstream(VER)
-
Return the upstream component of the given version string.
