  Returns the value of attribute name.

• #platform ⇒ Object readonly

  Returns the value of attribute platform.

• #version ⇒ Object readonly

  Returns the value of attribute version.

• .from_list(list) ⇒ Object

  Turn an array of [name, version, platform] into an array of NameTuple objects.

• .null ⇒ Object

  A null NameTuple, ie name=nil, version=0.

• .to_basic(list) ⇒ Object

  Turn an array of NameTuple objects back into an array of [name, version, platform] tuples.

• #<=>(other) ⇒ Object
• #==(other) ⇒ Object (also: #eql?)

  Compare with other.

• #full_name ⇒ Object

  Returns the full name (name-version) of this Gem.

• #hash ⇒ Object
• #initialize(name, version, platform = Gem::Platform::RUBY) ⇒ NameTuple constructor

  A new instance of NameTuple.

• #inspect ⇒ Object (also: #to_s)

  :nodoc:.

• #match_platform? ⇒ Boolean

  Indicate if this NameTuple matches the current platform.

• #prerelease? ⇒ Boolean

  Indicate if this NameTuple is for a prerelease version.

• #spec_name ⇒ Object

  Return the name that the gemspec file would be.

• #to_a ⇒ Object

  Convert back to the [name, version, platform] tuple.
