## Detailed Description

template<class Container>
class APT::PackageContainer< Container >

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

## Member Function Documentation

## ◆ clear()

template<class Container>

void clear | ( |  | ) |
| inline override virtual

Implements PackageContainerInterface.

## ◆ empty()

template<class Container>

bool empty | ( |  | ) | const
| inline nodiscard override virtual

Implements PackageContainerInterface.

## ◆ FromCommandLine()

template<class Container>

PackageContainer FromCommandLine | ( | pkgCacheFile & | Cache,
|  | const char ** | cmdline,
|  | CacheSetHelper & | helper )
| inline 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

## ◆ FromRegEx()

template<class Container>

PackageContainer FromRegEx | ( | pkgCacheFile & | Cache,
|  | std::string const & | pattern,
|  | CacheSetHelper & | helper )
| inline static

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

A simple helper responsible for executing a regular expression on all package names in the cache. Optional it prints 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

## ◆ FromString()

template<class Container>

PackageContainer FromString | ( | pkgCacheFile & | Cache,
|  | std::string const & | pattern,
|  | CacheSetHelper & | helper )
| inline static

returns all packages specified by a string

Parameters

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

## ◆ FromTask()

template<class Container>

PackageContainer FromTask | ( | pkgCacheFile & | Cache,
|  | std::string const & | pattern,
|  | CacheSetHelper & | helper )
| inline 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 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

## ◆ GroupedFromCommandLine()

template<class Container>

std::map< unsigned short, PackageContainer > GroupedFromCommandLine | ( | pkgCacheFile & | Cache,
|  | const char ** | cmdline,
|  | std::list< CacheSetHelper::PkgModifier > const & | mods,
|  | unsigned short const & | fallback,
|  | CacheSetHelper & | helper )
| inline 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

## ◆ insert() [1/4]

bool insert | ( | pkgCache::PkgIterator const & | P | ) |
| inline virtual

Implements PackageContainerInterface.

## ◆ insert() [2/4]

bool insert | ( | pkgCache::PkgIterator const & | P | ) |
| inline virtual

Implements PackageContainerInterface.

## ◆ insert() [3/4]

bool insert | ( | pkgCache::PkgIterator const & | P | ) |
| inline virtual

Implements PackageContainerInterface.

## ◆ insert() [4/4]

template<class Container>

bool insert | ( | pkgCache::PkgIterator const & | P | ) |
| inline override virtual

Implements PackageContainerInterface.

## ◆ size()

template<class Container>

size_t size | ( |  | ) | const
| inline nodiscard override virtual

Implements PackageContainerInterface.

## ◆ sort()

template<class Container>
template<class Compare>

bool sort | ( | Compare |  | ) |
| inline

sort all included versions with given comparer

Some containers are sorted by default, some are not and can't be, but a few like std::vector can be sorted if need be, so this can be specialized in later on. The default is that this will fail though. Specifically, already sorted containers like std::set will return false as well as there is no easy way to check that the given comparer would sort in the same way the set is currently sorted

Returns
  true if the set was sorted, false if not.
