Detailed Description

Package/Selection import and export.

PMPackageImEx is able to remember the current systems packages/selections. This information might be written to and restored from file.

Previously remember information may be used to arrange package/selection managers settings, to restore the systems content as close as possible.

Member Function Documentation

bool PMPackageImEx::collect_Pkg ( const constPMSelectablePtr & sel_r ) [inline, private]

Decides whether to remember data for the given package Selectable. If so, data are stored.

bool PMPackageImEx::collect_Sel ( const constPMSelectablePtr & sel_r ) [private]

Decides whether to remember data for the given selection Selectable. If so, data are stored.

bool PMPackageImEx::doExport ( const Pathname & path_r ) const

Expect path_r to denote a writable PMPackageImEx file, and store currently remembered PMPackageImEx data in it. Return false on any error. (we do not unlink any files on error!)

std::ostream & PMPackageImEx::doExport ( std::ostream & str ) const

Write currently remembered PMPackageImEx data to stream. On any error the streams FAIL and/or BAD bit is set.

bool PMPackageImEx::doImport ( const Pathname & path_r )

Expect path_r to be a readable PMPackageImEx file, and read it's data. Return false on any error.

std::istream & PMPackageImEx::doImport ( std::istream & str )

Read back PMPackageImEx data from stream. On any error (reading or parsing) the streams FAIL and/or BAD bit is set.
