twisted.protocols.policies.LimitTotalConnectionsFactory

class documentation

class LimitTotalConnectionsFactory(ServerFactory): (source)

Factory that limits the number of simultaneous connections.

Method	`buildProtocol`	Create an instance of a subclass of Protocol.
Method	`registerProtocol`	Undocumented
Method	`unregisterProtocol`	Undocumented
Class Variable	`connectionLimit`	maximum number of connections.
Class Variable	`overflowProtocol`	Protocol to use for new connections when connectionLimit is exceeded. If `None` (the default value), excess connections will be closed immediately.
Instance Variable	`connectionCount`	number of current connections.

Inherited from Factory (via ServerFactory):

Class Method	`forProtocol`	Create a factory for the given protocol.
Method	`doStart`	Make sure startFactory is called.
Method	`doStop`	Make sure stopFactory is called.
Method	`logPrefix`	Describe this factory for log messages.
Method	`startFactory`	This will be called before I begin listening on a Port or Connector.
Method	`stopFactory`	This will be called before I stop listening on all Ports/Connectors.
Class Variable	`noisy`	Undocumented
Class Variable	`protocol`	Undocumented
Instance Variable	`numPorts`	Undocumented

def buildProtocol(self, addr): (source) ¶

from twisted.internet.interfaces.IProtocolFactory

overrides twisted.internet.protocol.Factory.buildProtocol

overridden in twisted.protocols.ftp.FTPFactory

Create an instance of a subclass of Protocol.

The returned instance will handle input on an incoming server connection, and an attribute "factory" pointing to the creating factory.

Alternatively, None may be returned to immediately close the new connection.

Override this method to alter how Protocol instances get created.

Parameters
addr	an object implementing `IAddress`

def registerProtocol(self, p): (source) ¶

def unregisterProtocol(self, p): (source) ¶
