capability

Converts a string to a capability object for rpm dependency version comparisons. Strings with version information take the form capability relation version, where relation is one of {<,>,>=,<=,=}. If a relation and version are not specified, then comparisons will assume a capability at any version number.

Returns a capability object matching this string if some package in the RPM database provides that capability.

Returns capability objects that conflict with this package in the RPM database.

The list of actual files that the package leaves installed.

Returns a capability object that this package obsoletes.

Returns capability objects for each capability that this package provides.

Returns capability objects for each capability that this package requires.

Returns the name of this capability object.

If this capability object has version information, the relation is returned.Example: relation of capability "sh <= 4.1" - Returns "<=", the "less than or equal" relation.

If this capability object has version information, the version is returned.Example: version of capability "sh <= 4.1" - Returns "4.1", the version of the specified capability.

Creates a string containing the capability's name, relation and version.Example: capability "libxml2 >= 2.4.7" - Casts the capability as a string, returning "libxml2 >= 2.4.7".

Returns a boolean TRUE if the first capability satisfies the dependency specified by the second capability. A capability without version information is interpreted as a capability over all versions. If a package requires a capability not contained in the RPM database, then the rpm command will not allow that package to be installed.Example: capability "x" contains capability "x = 1.0" - Returns True. Having "x" at any version satisfies a requirement to have "x" at version 1.0.Example: capability "x = 1.0" contains capability "x" - Returns True. Having "x" at version 1.0 satisfies a requirement to have "x" at any version.Example: capability "x = 1.0" contains capability "x > 1.0" - Returns False. Having x = version 1.0 will not satisfy a requirement to have x > version 1.0.Example: capability "x = 1.0" contains capability "x < 2.0" - Returns True. Having x = version 1.0 will satisfy a requirement to have x < version 2.0.Example: capability "x" contains capability "y" - Returns False. A capability can only be contained/satisfied by a capability with the same name.
