Constructor Details

#initialize(options = {}) ⇒ BitString #initialize(value, options = {}) ⇒ BitString

Returns a new instance of BitString.

Overloads:

  • #initialize(options = {}) ⇒ BitString

    Parameters:

    • options (Hash) (defaults to: {})

    Options Hash (options):

    • :bit_length (Object) —

      default bit_length value. Should be present if :default is set

  • #initialize(value, options = {}) ⇒ BitString

    Parameters:

    • value (Object) —

      value to set for this ASN.1 object

    • options (Hash) (defaults to: {})

    Options Hash (options):

    • :bit_length (Object) —

      default bit_length value. Should be present if :default is set
