类 Gem::Resolver::LockSpecification

LockSpecification 来自锁定文件 (Gem::RequestSet::Lockfile)。

LockSpecification 的依赖信息从锁定文件中预先填充。

属性

公共类方法

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

源代码

# 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

调用父类方法 Gem::Resolver::Specification::new

公共实例方法

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

源代码

# 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

这是一个空安装，因为锁定的规范被认为是已安装的。options 被忽略。

调用父类方法 Gem::Resolver::Specification#install

spec ()

源代码

# File lib/rubygems/resolver/lock_specification.rb, line 73
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
