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.

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.

| 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.

| 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.

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.
