twisted.names.test.test_dns.OPTNonStandardAttributes

Generate byte and instance representations of an dns._OPTHeader where all attributes are set to non-default values.

For testing whether attributes have really been read from the byte string during decoding.

Class Method	bytes	Return `bytes` representing an encoded OPT record.
Class Method	object	Return a new `dns._OPTHeader` instance.

@classmethod
def bytes(cls, excludeName=False, excludeOptions=False):

Return bytes representing an encoded OPT record.

Parameters	excludeName	A flag that controls whether to exclude the name field. This allows a non-standard name to be prepended during the test. (type: `bool`)
	excludeOptions	A flag that controls whether to exclude the RDLEN field. This allows encoded variable options to be appended during the test. (type: `bool`)
Returns	`bytes` representing the encoded OPT record returned by `object`.

@classmethod
def object(cls):

Return a new dns._OPTHeader instance.

Returns A dns._OPTHeader instance with attributes that match the encoded record returned by bytes.
