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 Function Documentation

◆ ZYPP_DECLARE_FLAGS()

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

◆ valid()

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