Method getComponentByName

pager_lib/pyasn1/type/univ.py:2343–2380

Returns |ASN.1| type component by name. Equivalent to Python :class:`dict` subscription operation (e.g. `[]`). Parameters ---------- name: :class:`str` |ASN.1| type component name Keyword Args ------------ default: :class:`object

(self, name, default=noValue, instantiate=True)

        default: :class:`object`
            If set and requested component is a schema object, return the `default`
            object instead of the requested component.

        instantiate: :class:`bool`
            If :obj:`True` (default), inner component will be automatically
            instantiated.
            If :obj:`False` either existing component or the :class:`NoValue`
            object will be returned.
