## ◆ 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.
