class twisted.names.dns.Record_NULL(tputil.FancyStrMixin, tputil.FancyEqMixin): (source)
Implements interfaces: twisted.names.dns.IEncodableRecord
A null record.
This is an experimental record type.
Instance Variable | ttl | The maximum number of seconds which this record should be cached. |
Class Variable | fancybasename | Undocumented |
Class Variable | showAttributes | Undocumented |
Class Variable | compareAttributes | Undocumented |
Method | __init__ | Undocumented |
Instance Variable | payload | Undocumented |
Method | encode | Write a representation of this object to the given file object. |
Method | decode | Reconstruct an object from data read from the given file object. |
Method | __hash__ | Undocumented |
Inherited from FancyStrMixin:
Method | __str__ | Undocumented |
Inherited from FancyEqMixin:
Method | __eq__ | Undocumented |
Method | __ne__ | Undocumented |
Write a representation of this object to the given file object.
Parameters | strio | The buffer to write to. It must have a tell() method. (type: File-like object) |
compDict | A mapping of names to byte offsets that have already been written to the buffer, which may be used for compression (see RFC 1035 section 4.1.4). When None , encode without compression. (type: dict of bytes to int r None ) |
Reconstruct an object from data read from the given file object.
Parameters | strio | A seekable buffer from which bytes may be read. (type: File-like object) |
length | The number of bytes in this RDATA field. Most implementations can ignore this value. Only in the case of records similar to TXT where the total length is in no way encoded in the data is it necessary. (type: int or None ) |
