Overview

This class encapsulates a dependency resolver. The resolver is responsible for determining which set of dependencies to activate, with feedback from the #specification_provider

Defined Under Namespace

Classes: Resolution

Instance Attribute Summary

• #resolver_ui ⇒ UI readonly

  The UI module used to communicate back to the user during the resolution process.

• #specification_provider ⇒ SpecificationProvider readonly

  The specification provider used in the resolution process.

Instance Method Summary

• #initialize(specification_provider, resolver_ui) ⇒ Resolver constructor

  Initializes a new resolver.

• #resolve(requested, base = DependencyGraph.new) ⇒ Object

  Resolves the requested dependencies into a DependencyGraph, locking to the base dependency graph (if specified).

Constructor Details

#initialize(specification_provider, resolver_ui) ⇒ Resolver

Initializes a new resolver.

Parameters:

• specification_provider (SpecificationProvider) —

  see #specification_provider

• resolver_ui (UI) —

  see #resolver_ui

# File 'lib/rubygems/vendor/molinillo/lib/molinillo/resolver.rb', line 27

def initialize(specification_provider, resolver_ui)
  @specification_provider = specification_provider
  @resolver_ui = resolver_ui
end

Instance Attribute Details

#resolver_ui ⇒ UI (readonly)

Returns the UI module used to communicate back to the user during the resolution process.

Returns:

• (UI) —

  the UI module used to communicate back to the user during the resolution process

# File 'lib/rubygems/vendor/molinillo/lib/molinillo/resolver.rb', line 20

def resolver_ui
  @resolver_ui
end

#specification_provider ⇒ SpecificationProvider (readonly)

Returns the specification provider used in the resolution process.

Returns:

• (SpecificationProvider) —

  the specification provider used in the resolution process

# File 'lib/rubygems/vendor/molinillo/lib/molinillo/resolver.rb', line 16

def specification_provider
  @specification_provider
end

Instance Method Details

#resolve(requested, base = DependencyGraph.new) ⇒ Object

Resolves the requested dependencies into a DependencyGraph, locking to the base dependency graph (if specified)

Parameters:

• requested (Array) —

  an array of ‘requested’ dependencies that the #specification_provider can understand

• base (DependencyGraph, nil) (defaults to: DependencyGraph.new) —

  the base dependency graph to which dependencies should be ‘locked’

# File 'lib/rubygems/vendor/molinillo/lib/molinillo/resolver.rb', line 38

def resolve(requested, base = DependencyGraph.new)
  Resolution.new(specification_provider,
                 resolver_ui,
                 requested,
                 base).
