## Detailed Description

template<class Container>
class APT::VersionContainer< Container >

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

## Member Function Documentation

## ◆ clear()

template<class Container>

void clear | ( |  | ) |
| inlineoverridevirtual

Implements VersionContainerInterface.

## ◆ empty()

template<class Container>

bool empty | ( |  | ) | const
| inlinenodiscardoverridevirtual

Implements VersionContainerInterface.

## ◆ FromCommandLine()

template<class Container>

VersionContainer FromCommandLine | ( | pkgCacheFile & | Cache,
|  | const char ** | cmdline,
|  | CacheSetHelper::VerSelector const | fallback,
|  | CacheSetHelper & | helper )
| inlinestatic

returns all versions specified on the commandline

Get all versions from the commandline, uses given default version if non specifically requested and executes regex's if needed on names.

Parameters

  Cache | the packages and versions are in
  cmdline | Command line the versions should be extracted from
  fallback | version specification
  helper | responsible for error and message handling

## ◆ FromPackage()

template<class Container>

VersionContainer FromPackage | ( | pkgCacheFile & | Cache,
|  | pkgCache::PkgIterator const & | P,
|  | CacheSetHelper::VerSelector const | fallback,
|  | CacheSetHelper & | helper )
| inlinestatic

returns all versions specified for the package

Parameters

  Cache | the package and versions are in
  P | the package in question
  fallback | the version(s) you want to get
  helper | the helper used for display and error handling

## ◆ insert() [1/4]

bool insert | ( | pkgCache::VerIterator const & | V | ) |
| inlinevirtual

Implements VersionContainerInterface.

## ◆ insert() [2/4]

bool insert | ( | pkgCache::VerIterator const & | V | ) |
| inlinevirtual

Implements VersionContainerInterface.

## ◆ insert() [3/4]

bool insert | ( | pkgCache::VerIterator const & | V | ) |
| inlinevirtual

Implements VersionContainerInterface.

## ◆ insert() [4/4]

template<class Container>

bool insert | ( | pkgCache::VerIterator const & | V | ) |
| inlineoverridevirtual

Implements VersionContainerInterface.

## ◆ size()

template<class Container>

size_t size | ( |  | ) | const
| inlinenodiscardoverridevirtual

Implements VersionContainerInterface.

## ◆ 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.
