Detailed Description

Subclass to retrieve database content.

Definition at line 490 of file librpmDb.h.


Constructor & Destructor Documentation

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 710 of file librpmDb.cc.

References findAll().

Destructor.

Member Function Documentation

db_const_iterator& zypp::target::rpm::librpmDb::db_const_iterator::operator= ( const db_const_iterator ) [private]

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 766 of file librpmDb.cc.

References zypp::target::rpm::librpmDb::_d.

void zypp::target::rpm::librpmDb::db_const_iterator::operator++ ( )

Advance to next RpmHeader::constPtr.

Definition at line 733 of file librpmDb.cc.

References zypp::target::rpm::librpmDb::_d.

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

Definition at line 744 of file librpmDb.cc.

References zypp::target::rpm::librpmDb::_d.

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 755 of file librpmDb.cc.

References zypp::target::rpm::librpmDb::_d.

Referenced by operator->().

const RpmHeader::constPtr& zypp::target::rpm::librpmDb::db_const_iterator::operator-> ( ) const [inline]

Forwards to the current RpmHeader::constPtr.

Definition at line 549 of file librpmDb.h.

References operator*().

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::findByFile ( const std::string &  file_r)

Reset to iterate all packages that own a certain file.

Reset to iterate all packages that conflict with a certain tag.

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.

bool zypp::target::rpm::librpmDb::db_const_iterator::findPackage ( const std::string &  name_r,
const Edition ed_r
