@return [Set<Vertex>] the vertices of {#graph} where ‘self` is a
{#descendent?}
@param [Set<Vertex>] vertices the set to add the predecessors to @return [Set<Vertex>] the vertices of {#graph} where ‘self` is a

Build an array of PossibilitySets, with each element representing a group of dependency versions that all have the same sub-dependency version constraints and are contiguous. @param [Array] possibilities an array of possibilities @return [Array<PossibilitySet>] an array of possibility sets
Is there a path from ‘other` to `self` following edges in the dependency graph? @return whether there is a path following edges within this {#graph}
@param [String] name @return [Vertex,nil] the root vertex with the given name
Quietly ensure the Gem directory dir contains all the proper subdirectories for handling default gems. If we can’t create a directory due to a permission problem, then we will silently continue.
If mode is given, missing directories are created with this mode.
World-writable directories will never be created.
Sets the curve parameters. generator must be an instance of EC::Point that is on the curve. order and cofactor are integers.
See the OpenSSL documentation for EC_GROUP_set_generator()
Load extra data embed into binary format String object.
Gets the initial Negotiate token. Returns it as a base64 encoded string suitable for use in HTTP. Can be easily decoded, however.
