Member Function Documentation

◆ description()

const std::string & zypp::ResolverProblem::description ( ) const

Return a one-line description of the problem.

Definition at line 112 of file ResolverProblem.cc.

◆ details()

const std::string & zypp::ResolverProblem::details ( ) const

Definition at line 121 of file ResolverProblem.cc.

◆ solutions()

const ProblemSolutionList & zypp::ResolverProblem::solutions ( ) const

Return the possible solutions to this problem.

All problems should have at least 2-3 (mutually exclusive) solutions:

Undo: Do not perform the offending transaction (do not install the package that had unsatisfied requirements, do not remove the package that would break other packages' requirements)
Remove referrers: Remove all packages that would break because they depend on the package that is requested to be removed
Ignore: Inject artificial "provides" for a missing requirement (pretend that requirement is satisfied)

Definition at line 118 of file ResolverProblem.cc.

◆ setDescription()

void zypp::ResolverProblem::setDescription ( std::string description )

Set description of the problem.

Definition at line 124 of file ResolverProblem.cc.

◆ setDetails()

void zypp::ResolverProblem::setDetails ( std::string details )

Set detail description of the problem.

◆ addSolution()

void zypp::ResolverProblem::addSolution	(	ProblemSolution_Ptr	solution,
		bool	inFront = `false`
	)

Add a solution to this problem.

This class takes over ownership of the problem and will delete it when neccessary.
