twisted.protocols.basic.Int8StringReceiver(IntNStringReceiver) class documentationtwisted.protocols.basic
(View In Hierarchy)
Known subclasses: twisted.protocols.test.test_basic.TestInt8
A receiver for int8-prefixed strings.
An int8 string is a string prefixed by 1 byte, the 8-bit length of the string.
This class publishes the same interface as NetstringReceiver.
Inherited from IntNStringReceiver:
| Instance Variable | structFormat | format used for struct packing/unpacking. Define it in subclass. (type: str) |
| Instance Variable | prefixLength | length of the prefix, in bytes. Define it in subclass, using
struct.calcsize(structFormat) (type: int) |
| Method | stringReceived | Override this for notification when each complete string is received. |
| Method | lengthLimitExceeded | Callback invoked when a length prefix greater than
MAX_LENGTH is received. The default implementation
disconnects the transport. Override this. |
| Method | dataReceived | Convert int prefixed strings into calls to stringReceived. |
| Method | sendString | Send a prefixed string to the other end of the connection. |
| Instance Variable | _unprocessed | bytes received, but not yet broken up into messages / sent to
stringReceived. _compatibilityOffset must be updated when this value is
updated so that the recvd attribute can be generated
correctly. (type: bytes) |
| Instance Variable | _compatibilityOffset | the offset within _unprocessed to the next message to be
parsed. (used to generate the recvd attribute) (type: int) |
Inherited from Protocol (via IntNStringReceiver):
| Method | logPrefix | Return a prefix matching the class name, to identify log messages related to this protocol instance. |
| Method | connectionLost | Called when the connection is shut down. |
Inherited from BaseProtocol (via IntNStringReceiver, Protocol):
| Method | makeConnection | Make a connection to a transport and a server. |
| Method | connectionMade | Called when a connection is made. |
