Detailed Description

Libsolv transaction wrapper.

Note:: Note that Transaction is derived from sat::SolvIterMixin which makes PoolItem and Selectable iterators automatically available.; Changing the ResPool content (loading/unloading repositories) invalidates all outstanding transaction data.

See also:: valid.

Note:: .The transaction may inlude steps of type TRANSACTION_IGNORE which do not cause/require any specific action. To skip those informal steps when iterating, use the actionBegin /actionEnd methods.

Member Enumeration Documentation

enum zypp::sat::Transaction::StepType

Type of (rpm) action to perform in a Step.

Enumerator:

TRANSACTION_IGNORE	[ ] Nothing (includes implicit deletes due to obsoletes and non-package actions)
TRANSACTION_ERASE	[-] Delete item
TRANSACTION_INSTALL	[+] Install(update) item
TRANSACTION_MULTIINSTALL	[M] Install(multiversion) item ( See also: ZConfig::multiversion)

Definition at line 67 of file Transaction.h.

enum zypp::sat::Transaction::StepStage

Step action result.

Enumerator:

STEP_TODO	[__] unprocessed
STEP_DONE	[OK] success
STEP_ERROR	[**] error

Member Function Documentation

zypp::sat::Transaction::ZYPP_DECLARE_FLAGS	(	StepStages	,

bool zypp::sat::Transaction::valid ( ) const

Whether transaction actually contains data and also fits the current pools content.

Definition at line 312 of file Transaction.cc.

bool zypp::sat::Transaction::order ( )

Order transaction steps for commit.

It's cheap to call it for an aleready ordered Transaction. This invalidates outstanding iterators. Returns whether Transaction is valid.

Definition at line 315 of file Transaction.cc.

bool zypp::sat::Transaction::empty ( ) const

Whether the transaction contains any steps.

Reimplemented from zypp::sat::SolvIterMixin< Transaction, detail::Transaction_const_iterator >.

Definition at line 318 of file Transaction.cc.

size_t zypp::sat::Transaction::size ( ) const

Number of steps in transaction steps.
