(View In Hierarchy)
Known subclasses: twisted.protocols.basic.Int16StringReceiver, twisted.protocols.basic.Int32StringReceiver, twisted.protocols.basic.Int8StringReceiver
Generic class for length prefixed protocols.
| 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) |

correctly. (type: bytes)
struct.calcsize(structFormat) (type: int)
_unprocessed to the next message to be
parsed. (used to generate the recvd attribute) (type: int)
Override this for notification when each complete string is received.
| Parameters | string | The complete string which was received with all framing (length prefix,
etc) removed. (type: bytes) |
Callback invoked when a length prefix greater than
MAX_LENGTH is received. The default implementation
disconnects the transport. Override this.
| Parameters | length | The length prefix which was received. (type: int) |
Convert int prefixed strings into calls to stringReceived.
Send a prefixed string to the other end of the connection.
| Parameters | string | The string to send. The necessary framing (length prefix, etc) will be
added. (type: bytes) |
