Detailed Description

Subclass to retrieve database content.

Definition at line 335 of file librpmDb.h.

Constructor & Destructor Documentation

◆ db_const_iterator() [1/2]

zypp::target::rpm::librpmDb::db_const_iterator::db_const_iterator ( const db_const_iterator & )

private

◆ db_const_iterator() [2/2]

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 636 of file librpmDb.cc.

◆ ~db_const_iterator()

zypp::target::rpm::librpmDb::db_const_iterator::~db_const_iterator ( )

Destructor.

Definition at line 648 of file librpmDb.cc.

Member Function Documentation

◆ operator=()

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

private

◆ dbError()

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 692 of file librpmDb.cc.

◆ operator++()

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

Advance to next RpmHeader::constPtr.

Definition at line 659 of file librpmDb.cc.

◆ dbHdrNum()

unsigned zypp::target::rpm::librpmDb::db_const_iterator::dbHdrNum ( ) const

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

Definition at line 670 of file librpmDb.cc.

◆ operator*()

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 681 of file librpmDb.cc.

◆ operator->()

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

inline

Forwards to the current RpmHeader::constPtr.

Definition at line 394 of file librpmDb.h.

◆ findAll()

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 721 of file librpmDb.cc.

◆ findByFile()

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 732 of file librpmDb.cc.

◆ findByProvides()

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 743 of file librpmDb.cc.

◆ findByRequiredBy()

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 754 of file librpmDb.cc.

◆ findByConflicts()

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 765 of file librpmDb.cc.

◆ findByName()

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 776 of file librpmDb.cc.

◆ findPackage() [1/3]

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.

Definition at line 787 of file librpmDb.cc.

◆ findPackage() [2/3]

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 816 of file librpmDb.cc.

◆ findPackage() [3/3]

bool zypp::target::rpm::librpmDb::db_const_iterator::findPackage ( const Package::constPtr & which_r )

Abbr.

for findPackage( which_r->name(), which_r->edition() );
