Class Method Details

.it!(graph, demands, options = {}) ⇒ Hash

A quick solve. Given the “world” as we know it (the graph) and a list of requirements (demands) which must be met. Return me the best solution of artifacts and verisons that I should use.

If a ui object is passed in, the resolution will be traced

Parameters:

  • graph (Solve::Graph)
  • demands (Array<Solve::Demand>, Array<String, String>)
  • options (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (options):

  • :sorted (Boolean) — default: false —

    should the output be a sorted list rather than a Hash

Returns:

  • (Hash)

Raises:

  • (NoSolutionError)
