(View In Hierarchy)
Implements interfaces: twisted.names.dns.IEncodable
A resource record header.
Class Variable | fmt | str
specifying the byte format of an RR. |
Instance Variable | name | The name about which this reply contains information. (type: Name ) |
Instance Variable | type | The query type of the original request. (type: int ) |
Instance Variable | cls | The query class of the original request. |
Instance Variable | ttl | The time-to-live for this record. (type: int ) |
Instance Variable | payload | An object that implements the IEncodable
interface |
Instance Variable | auth | A bool
indicating whether this RRHeader was parsed from an
authoritative message. |
Method | __init__ | |
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 | isAuthoritative | Undocumented |
Method | __str__ | Undocumented |
Inherited from FancyEqMixin:
Method | __eq__ | Undocumented |
Method | __ne__ | Undocumented |
Parameters | name | See RRHeader.name (type: bytes
or unicode ) |
type | The query type. (type: int ) | |
cls | The query class. (type: int ) | |
ttl | Time to live for this record. This will be converted to an int . (type: int ) | |
payload | A Query Type specific data object. (type: An object implementing IEncodable ) | |
Raises | TypeError | if the ttl cannot be converted to an int . |
ValueError | if the ttl is negative. |
Write a representation of this object to the given file object.
Parameters | strio | The stream to which to write bytes (type: File-like object) |
compDict | A dictionary of backreference addresses that have already been written to
this stream and that may be used for compression. (type: dict or None ) |
Reconstruct an object from data read from the given file object.
Parameters | strio | The stream 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 ) |
