class Gem::Resolver::IndexSpecification

表示从 IndexSet 返回的可能的 Specification 对象。当只需要 name 和 version 时，用于延迟下载完整的 Specification 对象。

Public Class Methods

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

Source

# File lib/rubygems/resolver/index_specification.rb, line 18
def initialize(set, name, version, source, platform)
  super()

  @set = set
  @name = name
  @version = version
  @source = source
  @platform = Gem::Platform.new(platform.to_s)
  @original_platform = platform.to_s

  @spec = nil
end

一个 IndexSpecification 是根据 'gem help generate_index` 中描述的索引格式创建的。

set 包含此（URL）source 的其他规范。

name、version 和 platform 是 gem 的名称、版本和平台。

调用超类方法 Gem::Resolver::Specification::new

== (other)

Source

# File lib/rubygems/resolver/index_specification.rb, line 59
def ==(other)
  self.class === other &&
    @name == other.name &&
    @version == other.version &&
    @platform == other.platform
end

dependencies ()

Source

def dependencies
  spec.dependencies
end

此规范 gem 的依赖项

hash ()

Source

# File lib/rubygems/resolver/index_specification.rb, line 66
def hash
  @name.hash ^ @version.hash ^ @platform.hash
end

required_ruby_version ()

Source

# File lib/rubygems/resolver/index_specification.rb, line 44
def required_ruby_version
  spec.required_ruby_version || Gem::Requirement.default
end

此规范的 required_ruby_version 约束

包含一个回退，因为在生成时，一些已序列化的 spec 将其设置为 nil。

required_rubygems_version ()

Source

# File lib/rubygems/resolver/index_specification.rb, line 55
def required_rubygems_version
  spec.required_rubygems_version || Gem::Requirement.default
end

此规范的 required_rubygems_version 约束

包含一个回退，因为原始版本的规范 API 不包含该字段，所以索引中的一些已序列化 spec 将其设置为 nil。
