Constructor Details

#initialize(visibility: :public, explicit: true, parameters: [], node: nil, attribute: false, signatures: nil, anon_splat: false, **splat) ⇒ Method

Returns a new instance of Method.

Parameters:

  • visibility (::Symbol) (defaults to: :public) —

    :public, :protected, or :private

  • explicit (Boolean) (defaults to: true)
  • parameters (Array<Pin::Parameter>) (defaults to: [])
  • node (Parser::AST::Node, RubyVM::AbstractSyntaxTree::Node) (defaults to: nil)
  • attribute (Boolean) (defaults to: false)
