Constructor Details

#initialize(options = {}, &block) ⇒ Arguments

Initialize an Arguments

Parameters:

  • options (Hash) (defaults to: {})

Options Hash (options):

  • :required (Array[String]) —

    arguments that must be present before request is fired

  • :api (BitBucket::API) —

    the reference to the current api

def initialize(options = {}, &block)
  normalize! options

  @api      = options.fetch('api')

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method_name, *args, &block) ⇒ Object
