公共类方法

源代码

# File lib/rubygems/name_tuple.rb, line 24
def self.from_list(list)
  list.map {|t| new(*t) }
end

将 [name, version, platform] 数组转换为 NameTuple 对象数组。

new (name, version, platform=Gem::Platform::RUBY)

源代码

# File lib/rubygems/name_tuple.rb, line 9
def initialize(name, version, platform=Gem::Platform::RUBY)
  @name = name
  @version = version

  platform &&= platform.to_s
  platform = Gem::Platform::RUBY if !platform || platform.empty?
  @platform = platform
end

null ()

源代码

# File lib/rubygems/name_tuple.rb, line 39
def self.null
  new nil, Gem::Version.new(0), nil
end

一个空的 NameTuple，即 name=nil，version=0

to_basic (list)

源代码

# File lib/rubygems/name_tuple.rb, line 32
def self.to_basic(list)
  list.map(&:to_a)
end

将 NameTuple 对象数组转换回

name, version, platform: 元组数组。

公共实例方法

<=> (other)

源代码

# File lib/rubygems/name_tuple.rb, line 90
def <=>(other)
  [@name, @version, Gem::Platform.sort_priority(@platform)] <=>
    [other.name, other.version, Gem::Platform.sort_priority(other.platform)]
end

== (other)

源代码

# File lib/rubygems/name_tuple.rb, line 101
def ==(other)
  case other
  when self.class
    @name == other.name &&
      @version == other.version &&
      @platform == other.platform
  when Array
    to_a == other
  else
    false
  end
end

与 other 进行比较。支持另一个 NameTuple 或一个 [name, version, platform] 格式的 Array。

也别名为: eql?

eql? (other)

别名为: ==

full_name ()

源代码

# File lib/rubygems/name_tuple.rb, line 48
def full_name
  case @platform
  when nil, "", Gem::Platform::RUBY
    "#{@name}-#{@version}"
  else
    "#{@name}-#{@version}-#{@platform}"
  end
end

返回此 Gem 的完整名称（名称-版本）。如果不是默认的 Ruby 平台，则包含平台信息。这模仿了 Gem::Specification#full_name 的行为。

hash ()

源代码

# File lib/rubygems/name_tuple.rb, line 116
def hash
  to_a.hash
end

match_platform? ()

源代码

# File lib/rubygems/name_tuple.rb, line 60
def match_platform?
  Gem::Platform.match_gem? @platform, @name
end

指示此 NameTuple 是否与当前平台匹配。

prerelease? ()

源代码

# File lib/rubygems/name_tuple.rb, line 66
def prerelease?
  @version.prerelease?
end

指示此 NameTuple 是否用于预发布版本。

spec_name ()

源代码

# File lib/rubygems/name_tuple.rb, line 73
def spec_name
  "#{full_name}.gemspec"
end

返回 gemspec 文件将使用的名称

to_a ()

源代码

# File lib/rubygems/name_tuple.rb, line 80
def to_a
  [@name, @version, @platform]
end

转换回 [name, version, platform] 元组
