Member Function Documentation

def clientHardDisconnectTask (   self,
  task 
)
client did not tell us he was leaving but we lost connection to
him, so we need to update our data and tell others 
def flushTask (   self,
  task 
)
This task is run periodically to flush any connections
that might need it.  It's only necessary in cases where
collect-tcp is set true (if this is false, messages are sent
immediately and do not require periodic flushing). 
def getDoIdBase (   self,
  doId 
)
Given a doId, return the corresponding doIdBase.  This
will be the owner of the object (clients may only create
object doId's within their assigned range). 
def getTcpHeaderSize (   self)
Returns the current setting of TCP header size. See
setTcpHeaderSize(). 
def handleClientCreateObject (   self,
  datagram,
  dgi 
)
client wants to create an object, so we store appropriate
data, and then pass message along to corresponding zones 
def handleClientDeleteObject (   self,
  datagram,
  doId 
)
client deletes an object, let everyone who has interest in
the object's zone know about it. 
def handleClientDisconnect (   self,
  client 
)
def handleClientObjectSetZone (   self,
  datagram,
  dgi 
)
The client is telling us the object is changing to a new
zone. 
def handleClientObjectUpdateField (   self,
  datagram,
  dgi,
  targeted = False 
)
Received an update request from a client. 
def handleClientSetInterest (   self,
  client,
  dgi 
)
The client is specifying a particular set of zones it is
interested in. 
def handleDatagram (   self,
  datagram 
)
switching station for messages 
def handleMessageType (   self,
  msgType,
  di 
)
def importModule (   self,
  dcImports,
  moduleName,
  importSymbols 
)
Imports the indicated moduleName and all of its symbols
into the current namespace.  This more-or-less reimplements
the Python import command. 
def listenerPoll (   self,
  task 
)
def readDCFile (   self,
  dcFileNames = None 
)
Reads in the dc files listed in dcFileNames, or if
dcFileNames is None, reads in all of the dc files listed in
the Configrc file.
def readerPollOnce (   self)
checks for available messages to the server 
def readerPollUntilEmpty (   self,
  task 
)
continuously polls for new messages on the server 
def sendDoIdRange (   self,
  client 
)
sends the client the range of doid's that the client can
use 
def sendToAllExcept (   self,
  datagram,
  exceptionList 
)
sends a message to all connected clients, except for
clients on exceptionList. 
def sendToZoneExcept (   self,
  zoneId,
  datagram,
  exceptionList 
)
sends a message to everyone who has interest in the
indicated zone, except for the clients on exceptionList.
def setObjectZone (   self,
  owner,
  object,
  zoneId 
)
def setTcpHeaderSize (   self,
  headerSize 
)
Sets the header size of TCP packets.  At the present, legal
values for this are 0, 2, or 4; this specifies the number of
bytes to use encode the datagram length at the start of each
TCP datagram.  Sender and receiver must independently agree on
this.
def updateClientInterestZones (   self,
  client 
)
Something about the client has caused its set of interest
zones to potentially change.  Recompute them.
