### Public Class Methods

new (set, name, version, sources, platform)
Source

    # File lib/rubygems/resolver/lock_specification.rb, line 12
    def initialize(set, name, version, sources, platform)
      super()

      @name     = name
      @platform = platform
      @set      = set
      @source   = sources.first
      @sources  = sources
      @version  = version

      @dependencies = []
      @spec         = nil
    end

Calls superclass method `Gem::Resolver::Specification::new`

### Public Instance Methods

install (options = {}) { |nil| ... }
Source

    # File lib/rubygems/resolver/lock_specification.rb, line 30
    def install(options = {})
      destination = options[:install_dir] || Gem.dir

      if File.exist? File.join(destination, "specifications", spec.spec_name)
        yield nil
        return
      end

      super
    end

This is a null install as a locked specification is considered installed. `options` are ignored.

    def spec
      @spec ||= Gem::Specification.find do |spec|
        spec.name == @name && spec.version == @version
      end

      @spec ||= Gem::Specification.new do |s|
        s.name     = @name
        s.version  = @version
        s.platform = @platform

        s.dependencies.concat @dependencies
      end
    end

A specification constructed from the lockfile is returned
