@return [Object] most up-to-date dependency in the possibility set
Processes the topmost available {RequirementState} on the stack @return [void]
Creates and pushes the initial state for the resolution, based upon the {#requested} dependencies @return [void]
@param [Object] possibility a single possibility @param [Array] requirements an array of requirements @return [Boolean] whether the possibility satisfies all of the
given requirements
@param [Object] requirement @return [ResolutionState] the state whose ‘requirement` is the given
`requirement`.
Add the current {#possibility} to the dependency graph of the current {#state} @return [void]
Raises a VersionConflict error, or any underlying error, if there is no current state @return [void]
Pushes a new {DependencyState} that encapsulates both existing and new requirements @param [Array] new_requirements @param [Boolean] requires_sort @param [Object] new_activated @return [void]
@return [Boolean] where the requirement of the state we’re unwinding
to directly caused the conflict. Note: in this case, it is impossible for the state we're unwinding to to be a parent of any of the other conflicting requirements (or we would have circularity)
Filter’s a state’s possibilities to remove any that would not satisfy the requirements in the conflict we’ve just rewound from @param [UnwindDetails] unwind_details details of the conflict just unwound from @return [void]
Attempts to update the existing vertex’s ‘PossibilitySet` with a filtered version @return [void]
Pushes a new {DependencyState}. If the {#specification_provider} says to {SpecificationProvider#allow_missing?} that particular requirement, and there are no possibilities for that requirement, then ‘state` is not pushed, and the vertex in {#activated} is removed, and we continue resolving the remaining requirements. @param [DependencyState] state @return [void]
Ensures any raised {NoSuchDependencyError} has its {NoSuchDependencyError#required_by} set. @yield
