Method Details

### __init__(self, factory, wrappedProtocol, timeoutPeriod) (Constructor) Constructor. Parameters: `factory` - An `IFactory`. `wrappedProtocol` - A `Protocol` to wrapp. `timeoutPeriod` - Number of seconds to wait for activity before timing out.

### cancelTimeout(self) Cancel the timeout. If the timeout was already cancelled, this does nothing.

### connectionLost(self, reason) Called when the connection is shut down. Clear any circular references here, and any external references to this Protocol. The connection has been closed. Parameters: `reason` (type=`twisted.python.failure.Failure`) Overrides: `twisted.protocols.policies.ProtocolWrapper.connectionLost` (inherited documentation)

### dataReceived(self, data) Called whenever data is received. Use this method to translate to a higher-level message. Usually, some callback will be made upon the receipt of each complete protocol message. Parameters: `data` - a string of indeterminate length. Please keep in mind that you will probably need to buffer some data, as partial (or multiple) protocol messages may be received! I recommend that unit tests for protocols call through to this method with differing chunk sizes, down to one byte at a time. Overrides: `twisted.protocols.policies.ProtocolWrapper.dataReceived` (inherited documentation)

### resetTimeout(self) Reset the timeout, usually because some activity just happened.

### setTimeout(self, timeoutPeriod=None) Set a timeout. This will cancel any existing timeouts. Parameters: `timeoutPeriod` - If not `None`, change the timeout period. Otherwise, use the existing value.

### timeoutFunc(self) This method is called when the timeout is triggered. By default it calls `loseConnection`. Override this if you want something else to happen.
