Member Function Documentation

detectSystemArchitecture()

Arch zypp::Arch::detectSystemArchitecture ( )

static

Determine system architecture evaluating uname and /proc/cpuinfo.

Definition at line 701 of file Arch.cc.

idStr()

IdString zypp::Arch::idStr

(

)

const

String representation of Arch.

Definition at line 716 of file Arch.cc.

asString() [1/2]

const std::string & zypp::Arch::asString

(

)

const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 724 of file Arch.cc.

c_str()

const char * zypp::Arch::c_str ( ) const

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 64 of file Arch.h.

empty()

bool zypp::Arch::empty ( ) const

inline

Test for an empty Arch (this is Arch_epmty, not Arch_noarch ).

Definition at line 68 of file Arch.h.

size()

unsigned zypp::Arch::size ( ) const

inline

Size of the string representation.

Definition at line 72 of file Arch.h.

id()

IdString::IdType zypp::Arch::id ( ) const

inline

Expert backdoor.

Definition at line 76 of file Arch.h.

isBuiltIn()

bool zypp::Arch::isBuiltIn

(

)

const

Whether this is a buitin (or known) architecture.

Used e.g. in Capability to determine whether some trailing ".string" is part ot the name or restriction to an architecture.

Definition at line 732 of file Arch.cc.

compatibleWith()

bool zypp::Arch::compatibleWith

(

const Arch &

targetArch_r

)

const

Compatibility relation.

Returns

True iff this is compatible with targetArch_r.

Arch_noarch.compatibleWith( ... )       ==> always true;
Arch_i686.compatibleWith( Arch_x86_64 ) ==> true;
Arch_x86_64.compatibleWith( Arch_i686 ) ==> false;

Definition at line 740 of file Arch.cc.

baseArch() [1/2]

Arch zypp::Arch::baseArch

(

)

const

Returns

the arch before noarch if it's not a multilib arch (e.g. x86_64,sparc64v,sparc64,ppc64,s390x).

Definition at line 748 of file Arch.cc.

baseArch() [2/2]

Arch zypp::Arch::baseArch ( const Arch & targetArch_r )

inlinestatic

Definition at line 106 of file Arch.h.

compare() [1/2]

int zypp::Arch::compare

(

const Arch &

rhs

)

const

Arch comparison.

Compatible architectures are treated as less (i.e. i686>i386>noarch). So Arch_noarch is the least Arch. Equivalent architectures (compatible in both directions) are ordered arbitrary.

Definition at line 785 of file Arch.cc.

compare() [2/2]

int zypp::Arch::compare ( const Arch & lhs, const Arch & rhs )

inlinestatic

Arch comparison (static version).

Definition at line 117 of file Arch.h.

compatSet()

Arch::CompatSet zypp::Arch::compatSet ( const Arch & targetArch_r )

static

Return a set of all Arch's compatibleWith a targetArch_r.

Note

The set is ordered according to compare, thus iterating will start at targetArch_r and end with Arch_noarch.

Arch::CompatSet cset( Arch::compatSet( Arch_x86_64 ) );
 
cout << str::join( make_transform_iterator( cset.begin(), std::mem_fn(&Arch::asString) ),
                   make_transform_iterator( cset.end(), std::mem_fn(&Arch::asString) ) )
     << endl;
 
// Prints: x86_64 athlon i686 i586 i486 i386 noarch

Definition at line 793 of file Arch.cc.

asString() [2/2]

std::string zypp::Arch::asString ( const CompatSet & cset )

inlinestatic

Definition at line 140 of file Arch.h.
