Detailed Description

Simple wrapper around a std::set to provide a similar interface to a set of packages as to the complete set of all packages in the pkgCache.

PackageSet FromCommandLine	(	pkgCacheFile &	Cache,
		const char **	cmdline,
		CacheSetHelper &	helper
	)			[static]

returns all packages specified on the commandline

Get all package names from the commandline and executes regex's if needed. No special package command is supported, just plain names.

Parameters:

	Cache	the packages are in
	cmdline	Command line the package names should be extracted from
	helper	responsible for error and message handling

pkgCache::PkgIterator FromName	(	pkgCacheFile &	Cache,
		std::string const &	string,
		CacheSetHelper &	helper
	)			[static]

returns a package specified by a string

Parameters:

	Cache	the package is in
	string	String the package name should be extracted from
	helper	responsible for error and message handling

PackageSet FromRegEx	(	pkgCacheFile &	Cache,
		std::string	pattern,
		CacheSetHelper &	helper
	)			[static]

returns all packages in the cache whose name matchs a given pattern

A simple helper responsible for executing a regular expression on all package names in the cache. Optional it prints a a notice about the packages chosen cause of the given package.

Parameters:

	Cache	the packages are in
	pattern	regular expression for package names
	helper	responsible for error and message handling

PackageSet FromString	(	pkgCacheFile &	Cache,
		std::string const &	string,
		CacheSetHelper &	helper
	)			[static]

returns all packages specified by a string

Parameters:

	Cache	the packages are in
	string	String the package name(s) should be extracted from
	helper	responsible for error and message handling

PackageSet FromTask	(	pkgCacheFile &	Cache,
		std::string	pattern,
		CacheSetHelper &	helper
	)			[static]

returns all packages in the cache who belong to the given task

A simple helper responsible for search for all members of a task in the cache. Optional it prints a a notice about the packages chosen cause of the given task.

Parameters:

	Cache	the packages are in
	pattern	name of the task
	helper	responsible for error and message handling

		const char **	cmdline,
		std::list< PackageSet::Modifier > const &	mods,
		unsigned short const &	fallback,
		CacheSetHelper &	helper
	)			[static]

group packages by a action modifiers

At some point it is needed to get from the same commandline different package sets grouped by a modifier. Take apt-get install apt awesome- as an example.

Parameters:

	Cache	the packages are in
	cmdline	Command line the package names should be extracted from
	mods	list of modifiers the method should accept
	fallback	the default modifier group for a package
	helper	responsible for error and message handling
