class Gem::Resolver::IndexSpecification

Represents a possible Specification object returned from IndexSet. Used to delay needed to download full Specification objects when only the name and version are needed.

Public Class Methods

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

An IndexSpecification is created from the index format described in ‘gem help generate_index`.

The set contains other specifications for this (URL) source.

The name, version and platform are the name, version and platform of the gem.

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

# 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

dependencies ()

The dependencies of the gem for this specification

# File lib/rubygems/resolver/index_specification.rb, line 34
def dependencies
  spec.dependencies
end

hash ()

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

required_ruby_version ()

The required_ruby_version constraint for this specification

A fallback is included because when generated, some marshalled specs have it set to nil.

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

required_rubygems_version ()

The required_rubygems_version constraint for this specification

A fallback is included because the original version of the specification API didn’t include that field, so some marshalled specs in the index have it set to nil.

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