protected IEnumerable<SolverDemand> DemandsFor(Command command, FeedUri interfaceUri)

Parameters

command Command

The command to scan for dependencies.

interfaceUri FeedUri

The interface URI of the feed providing the command.

Returns

IEnumerable<SolverDemand>

DemandsFor(ImplementationSelection, Requirements)

protected IEnumerable<SolverDemand> DemandsFor(ImplementationSelection selection, Requirements requirements)

Parameters

selection ImplementationSelection

The selection to scan for dependencies.

requirements Requirements

Requirements to inherit into the demands.
