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 96 of file ResolverProblem.cc.

Resolver_constPtr zypp::ResolverProblem::resolver ( ) const

inline

Return the parent dependency resolver.

Definition at line 104 of file ResolverProblem.h.

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.
