Member Function Documentation

bool PMManager::anyMatch ( PMSelectable::Test_fnc fnc_r ) const

General test whether fnc_r returns true for at least one Selectable.

Parameters:

fnc_r pointer to boolean test function taking a constPMSelectablePtr as argument.

bool PMManager::anyMatch ( PMSelectable::Test_method fnc_r ) const

General test whether fnc_r returns true for at least one Selectable.

Parameters:

fnc_r pointer to a boolean PMSelectable const method (e.g. PMSelectable::by_user).

bool PMManager::anythingByUser ( ) const [inline]

are there currently any "by_user" selectables ?

bool PMManager::anythingToDelete ( ) const [inline]

are there currently any selectables for deletion ?

bool PMManager::anythingToInstall ( ) const [inline]

are there currently any selectables for installation ?

virtual PMObjectPtr PMManager::assertObjectType ( const PMObjectPtr & object_r ) const [private, pure virtual]

Concrete Manager has to assert that the passed ObjectPtr actually references the correct type of Object (PackageManager e.g. will handle nothing else but Packages).
Implemented in PMLanguageManager, PMPackageManager, PMSelectionManager, and PMYouPatchManager.

PMSelectableVec::const_iterator PMManager::begin ( ) const [inline]

Iterator for Selectables within this Manager.

void PMManager::buildSets ( PkgSet & installed,

PkgSet & available,

PkgSet & to_install

) [private]

set maximum number of packages that will be automatically selected for removal on upgrade

void PMManager::checkPool ( ) const [private]

void PMManager::clearAll ( ) [private]

void PMManager::ClearSaveState ( ) [virtual]

Forgett a previously saved selection.
Reimplemented in PMSelectionManager.

bool PMManager::DiffState ( ) const [virtual]

Return true if current selection differs from previously saved selection.

bool PMManager::empty ( ) const [inline]

True if Manager does not contain any Selectable

PMSelectableVec::const_iterator PMManager::end ( ) const [inline]

Iterator for Selectables within this Manager.

PMSelectablePtr PMManager::getItem ( const std::string & name_t ) const [inline]

PMSelectablePtr to the Selectable with the given name, or NULL if there is none.

void PMManager::invalidateSolverSets ( ) [private]

PMSelectablePtr PMManager::newSelectable ( const PkgName & name_r ) const [private, virtual]

Currently we don't need concrete Selectables (e.g. PackageSelectable), thus new Selectables are created here. Otherwise make it pure virtual, and let the concrete Manager create the appropriate type of Selectable.

PMManager& PMManager::operator= ( const PMManager & ) [private]

PMSelectablePtr PMManager::operator[] ( const std::string & name_r ) const [inline]

PMSelectablePtr to the Selectable with the given name, or NULL if there is none.

void PMManager::poolAddCandidates ( PMObjectContainerIter iter_r )

Called from InstSrc to add provided Objects

void PMManager::poolAdjust ( ) [private]

Remove superfluous empty Selecatables. To be called after Objects were removed from Selectables.
This clears any saved state!

PMSelectablePtr PMManager::poolLookup ( const std::string & name_r ) const [private]

Lookup Selectable by name.

PMSelectablePtr PMManager::poolProvide ( const std::string & name_r ) [private]

Make shure the pool contains a Selectable named name_r, and return it.

void PMManager::poolRemoveCandidates ( PMObjectContainerIter iter_r )

Called from InstSrc to remove the formerly added objects.

void PMManager::poolSetInstalled ( PMObjectContainerIter iter_r )

Called from TargetSystem providing all(!) installed objects

void PMManager::poolSortCandidates ( )

Sort all Selectables candiadte lists. This has to be done whenever the sort criteria were changed (e.g. after reordeing the InstSrces).

virtual void PMManager::postPAC ( ) [inline, private, virtual]

Post poolAddCandidates hook
Reimplemented in PMSelectionManager.

virtual void PMManager::postPRC ( ) [inline, private, virtual]

Post poolRemoveCandidates hook
Reimplemented in PMSelectionManager.

virtual void PMManager::postPSI ( ) [inline, private, virtual]

Post poolSetInstalled hook
Reimplemented in PMLanguageManager, PMPackageManager, and PMSelectionManager.

virtual void PMManager::prePAC ( ) [inline, private, virtual]

Pre poolAddCandidates hook

virtual void PMManager::prePRC ( ) [inline, private, virtual]

Pre poolRemoveCandidates hook

virtual void PMManager::prePSI ( ) [inline, private, virtual]

Pre poolSetInstalled hook
Reimplemented in PMLanguageManager, and PMPackageManager.

PMSelectableVec::const_reverse_iterator PMManager::rbegin ( ) const [inline]

Iterator for Selectables within this Manager.

void PMManager::readSettings ( ) [virtual]

Read setting slike Taboo states from disk.

PMSelectableVec::const_reverse_iterator PMManager::rend ( ) const [inline]

Iterator for Selectables within this Manager.

bool PMManager::RestoreState ( ) [virtual]

Restore previously saved selection.
Reimplemented in PMSelectionManager.

void PMManager::SaveState ( ) [virtual]

Save current selection.
Reimplemented in PMSelectionManager.

void PMManager::selectableNotify ( constPMSelectablePtr item_r,

SelState old_r,

SelState new_r

) [private, virtual]

Receives trigger from Selectable on state change
Reimplemented in PMLanguageManager.

void PMManager::setNothingSelected ( )

Set all Selectables to NothingSelected ( neither install nor delete )

virtual Pathname PMManager::settingsFile ( ) const [inline, protected, virtual]

Return file name used to read and write settings. Subclasses should override this function and provide an appropriate filename, if they need their settings to be stored.
Reimplemented in PMYouPatchManager.

unsigned PMManager::size ( ) const [inline]

The number of Selectables within this Manager.

bool PMManager::solveConsistent ( PkgDep::ErrorResultList & bad )

determine whether installed system is consistent

Parameters:

bad broken packages

bool PMManager::solveInstall ( PkgDep::ResultList & good,

PkgDep::ErrorResultList & bad,

bool filter_conflicts_with_installed = false

)

resolve dependencies for packages marked for installation

Parameters:

good (output) list of PkgDep::Result that have been marked for installation/upgrade

bad (output) list of PkgDep::ErrorResult that have trouble
