Constructor Details

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

Returns a new instance of BitString.

Parameters:

  • name (Symbol, String) —

    name for this tag in grammar

  • options (Hash) (defaults to: {})

Options Hash (options):

  • :class (Symbol) —

    ASN.1 tag class. Default value is :universal

  • :optional (::Boolean) —

    define this tag as optional. Default is false

  • :default (Object) —

    default value for DEFAULT tag

  • :bit_length (Object) —

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