zypp::target::rpm::librpmDb::db_const_iterator::db_const_iterator | ( | librpmDb::constPtr | dbptr_r = 0 | ) |
Constructor.
Iterator is initialized to findAll. The default form accesses librpmDb's default database. Explicitly providing a database handle should not be neccesary, except for testing.
Definition at line 719 of file librpmDb.cc.
zypp::target::rpm::librpmDb::db_const_iterator::~db_const_iterator | ( | ) |
Destructor.

shared_ptr< RpmException > zypp::target::rpm::librpmDb::db_const_iterator::dbError | ( | ) | const |
Return any database error.
NOTE: If the database gets blocked (see dbRelease) dbError will immediately report this, but an already running iteration will proceed to its end. Then the database is dropped.
Definition at line 775 of file librpmDb.cc.
void zypp::target::rpm::librpmDb::db_const_iterator::operator++ | ( | ) |
Advance to next RpmHeader::constPtr.
Definition at line 742 of file librpmDb.cc.
unsigned zypp::target::rpm::librpmDb::db_const_iterator::dbHdrNum | ( | ) | const |
Returns the current headers index in database, 0 if no header.
Definition at line 753 of file librpmDb.cc.
const RpmHeader::constPtr & zypp::target::rpm::librpmDb::db_const_iterator::operator* | ( | ) | const |
Returns the current RpmHeader::constPtr or NULL, if no more entries available.
Definition at line 764 of file librpmDb.cc.
|
inline |
Forwards to the current RpmHeader::constPtr.
Definition at line 549 of file librpmDb.h.
bool zypp::target::rpm::librpmDb::db_const_iterator::findAll | ( | ) |
Reset to iterate all packages.
Returns true if iterator contains at least one entry.
NOTE: No entry (false) migt be returned due to a meanwhile blocked database (see dbRelease). Use dbError to check this.
Definition at line 804 of file librpmDb.cc.
bool zypp::target::rpm::librpmDb::db_const_iterator::findByFile | ( | const std::string & | file_r | ) |
Reset to iterate all packages that own a certain file.
Definition at line 815 of file librpmDb.cc.
bool zypp::target::rpm::librpmDb::db_const_iterator::findByProvides | ( | const std::string & | tag_r | ) |
Reset to iterate all packages that provide a certain tag.
Definition at line 826 of file librpmDb.cc.
bool zypp::target::rpm::librpmDb::db_const_iterator::findByRequiredBy | ( | const std::string & | tag_r | ) |
Reset to iterate all packages that require a certain tag.
Definition at line 837 of file librpmDb.cc.
bool zypp::target::rpm::librpmDb::db_const_iterator::findByConflicts | ( | const std::string & | tag_r | ) |
Reset to iterate all packages that conflict with a certain tag.
Definition at line 848 of file librpmDb.cc.
bool zypp::target::rpm::librpmDb::db_const_iterator::findByName | ( | const std::string & | name_r | ) |
Reset to iterate all packages with a certain name.
NOTE: Multiple entries for one package installed in different versions are possible but not desired. Usually you'll want to use findPackage instead.
findByName is needed to retrieve pseudo packages like 'gpg-pubkey', which in fact exist in multiple instances.
Definition at line 859 of file librpmDb.cc.
bool zypp::target::rpm::librpmDb::db_const_iterator::findPackage | ( | const std::string & | name_r | ) |
Find package by name.
Multiple entries for one package installed in different versions are possible but not desired. If so, the last package installed is returned.
bool zypp::target::rpm::librpmDb::db_const_iterator::findPackage | ( | const std::string & | name_r, |
const Edition & | ed_r | ||
) |
Find package by name and edition.
Commonly used by PMRpmPackageDataProvider.
Definition at line 899 of file librpmDb.cc.
bool zypp::target::rpm::librpmDb::db_const_iterator::findPackage | ( | const Package::constPtr & | which_r | ) |
