    #dependencies_equal?(dependencies, other_dependencies)  ⇒ Boolean 
  



  

    

Determines whether two arrays of dependencies are equal, and thus can be grouped.

    (Array<Object>)
  
    •

    other_dependencies
    (Array<Object>)
  
    • 



Returns:


    
  
  • 
    (Boolean)
—    
    

    whether dependencies and other_dependencies should be considered equal.

    #dependencies_for(specification)  ⇒ Array<Object> 
  



  

    
  

    Note:
    


This method should be ‘pure’, i.e. the return value should depend only on the ‘specification` parameter.

    (Object)
  
    • 



Returns:


    
  
  • 
    (Array<Object>)
—    
    

    the dependencies that are required by the given ‘specification`.

Returns:


    
  
  • 
    (String)
—    
    

    the name of the source of explicit dependencies, i.e. those passed to Resolver#resolve directly.

Returns:


    
  
  • 
    (String)
—

    #requirement_satisfied_by?(requirement, activated, spec)  ⇒ Boolean 
  



  

    

Determines whether the given requirement is satisfied by the given spec, in the context of the current activated dependency graph.


  





  
Parameters:


    
  
  • 
    requirement
    (Object)
  
    • 
  
  • 
    activated
    (DependencyGraph)
—    
    

    the current dependency graph in the resolution process.
    

    
  
    • 
  
  • 
    spec
    (Object)
  
    • 



Returns:


    
  
  • 
    (Boolean)
—    
    

    whether requirement is satisfied by spec in the context of the current ‘activated` dependency graph.

end


  








  

    #search_for(dependency)  ⇒ Array<Object> 
  



  

    
  

    Note:
    


This method should be ‘pure’, i.e. the return value should depend only on the ‘dependency` parameter.



  




Search for the specifications that match the given dependency. The specifications in the returned array will be considered in reverse order, so the latest version ought to be last.


  





  
Parameters:


    
  
  • 
    dependency
    (Object)
  
    • 



Returns:


    
  
  • 
    (Array<Object>)
—    
    

    the specifications that satisfy the given ‘dependency`.

end


  








  

    #sort_dependencies(dependencies, activated, conflicts)  ⇒ Array<Object> 
  



  

    

Sort dependencies so that the ones that are easiest to resolve are first. Easiest to resolve is (usually) defined by:



1) Is this dependency already activated?
2) How relaxed are the requirements?
3) Are there any conflicts for this dependency?
4) How many possibilities are there to satisfy this dependency?


  





  
Parameters:


    
  
  • 
    dependencies
    (Array<Object>)
  
    • 
  
  • 
    activated
    (DependencyGraph)
—    
    

    the current dependency graph in the resolution process.
    

    
  
    • 
  
  • 
    conflicts
    ({String => Array<Conflict>})
  
    • 



Returns:


    
  
  • 
    (Array<Object>)
—    
    

    a sorted copy of dependencies.

    #with_no_such_dependency_error_handling { ... }  (private)
  



  

    

Ensures any raised ::Bundler::Molinillo::NoSuchDependencyError has its NoSuchDependencyError#required_by set.
