## Member Function Documentation

## ◆ AddStatusFiles()

bool AddStatusFiles | ( | std::vector< pkgIndexFile * > & | List | ) |
| overridevirtual

Implements pkgSystem.

## ◆ ArchitecturesSupported()

std::vector< std::string > ArchitecturesSupported | ( |  | ) | const
| overridevirtual

architectures supported by this system

A MultiArch capable system might be configured to use this capability.

Returns
  a list of all architectures (native + foreign) configured for on this system (aka: which can be installed without force)

Implements pkgSystem.

## ◆ ArchiveSupported()

APT_PURE bool ArchiveSupported | ( | const char * | Type | ) |
| overridevirtual

Implements pkgSystem.

## ◆ CreatePM()

pkgPackageManager * CreatePM | ( | pkgDepCache * | Cache | ) | const
| overridevirtual

Implements pkgSystem.

## ◆ FindIndex()

bool FindIndex | ( | pkgCache::PkgFileIterator | File,
|  | pkgIndexFile *& | Found ) const
| overridevirtual

Implements pkgSystem.

## ◆ Initialize()

bool Initialize | ( | Configuration & | Cnf | ) |
| overridevirtual

Reimplemented from pkgSystem.

## ◆ IsLocked()

bool IsLocked | ( |  | ) |
| overridevirtual

checks if the system is currently locked

Implements pkgSystem.

## ◆ Lock()

bool Lock | ( | OpProgress * | Progress | ) |
| overridevirtual

Implements pkgSystem.

## ◆ LockInner()

bool LockInner | ( | OpProgress *const | Progress,
|  | int | timeoutSec )
| overridevirtual

Implements pkgSystem.

## ◆ MultiArchSupported()

bool MultiArchSupported | ( |  | ) | const
| overridevirtual

Todo
  these methods should be virtual

does this system has support for MultiArch?

Systems supporting only single arch (not systems which are single arch) are considered legacy systems and support for it will likely degrade over time.

The default implementation returns always true.

Returns
  true if the system supports MultiArch, false if not.

Implements pkgSystem.

## ◆ Score()

signed Score | ( | Configuration const & | Cnf | ) |
| overridevirtual

Reimplemented from pkgSystem.

## ◆ UnLock()

bool UnLock | ( | bool | NoErrors = false | ) |
| overridevirtual

Implements pkgSystem.

## ◆ UnLockInner()

bool UnLockInner | ( | bool | NoErrors = false | ) |
| overridevirtual

Implements pkgSystem.
