Class Method Details

.generate_version_locking_dependencies(lockfile, pods_to_update) ⇒ Molinillo::DependencyGraph<Dependency>

Generates dependencies that require the specific version of the Pods that haven’t changed in the Lockfile.

These dependencies are passed to the Resolver, unless the installer is in update mode, to prevent it from upgrading the Pods that weren’t changed in the Podfile.

Returns:

  • (Molinillo::DependencyGraph<Dependency>) —

    the dependencies generated by the lockfile that prevent the resolver to update a Pod.

.unlocked_dependency_graph ⇒ Molinillo::DependencyGraph<Dependency>

Generates a completely ‘unlocked’ dependency graph.

Returns:

  • (Molinillo::DependencyGraph<Dependency>) —

    an empty dependency graph
