Member Function Documentation

ArchitecturesSupported()

virtual std::vector< std::string > ArchitecturesSupported ( ) const

pure virtual

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)

Implemented in debSystem, and edspLikeSystem.

IsLocked()

virtual bool IsLocked ( )

pure virtual

checks if the system is currently locked

Implemented in debSystem, and edspLikeSystem.

Referenced by pkgDPkgPM::Go().

MultiArchSupported()

virtual bool MultiArchSupported ( ) const

pure virtual

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.

Implemented in debSystem, and edspLikeSystem.

Referenced by pkgDPkgPM::Go(), and StateChanges::Save().
