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 657 of file librpmDb.cc. References findAll(). |

Destructor.
Definition at line 669 of file librpmDb.cc. References _d. |

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 713 of file librpmDb.cc.

Returns the current headers index in database, 0 if no header.

Returns the current RpmHeader::constPtr or NULL, if no more entries available.

|
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 742 of file librpmDb.cc. References _d, and zypp::target::rpm::librpmDb::db_const_iterator::D::init(). Referenced by db_const_iterator(). |

Reset to iterate all packages that own a certain file.

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. Referenced by zypp::target::rpm::RpmDb::pubkeyEditions(), and zypp::target::rpm::RpmDb::pubkeys(). |
|
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. Referenced by zypp::target::rpm::RpmDb::fileList(), findPackage(), and zypp::target::rpm::RpmDb::getData(). |

Find package by name and edition. Commonly used by PMRpmPackageDataProvider. Definition at line 835 of file librpmDb.cc.
