-
batch
(requests, connection, container, raiseonerror=True)¶ Send multiple requests, return when all the requests are done. Requests can have no responses. The attributes are set even if an OpenflowErrorResultException is raised.
Returns: (openflow_reply, openflow_replydict) in which openflow_reply is the list of messages in receiving order. openflow_replydict is the dictionary {request:reply}. Raises: OpenflowErrorResultException – when some replies are errors. exc.result returns (openflow_reply, openflow_replydict)
-
closed
(connection)¶ routine for connection closed
-
error
(connection)¶ routine for connection error
-
init
(connection)¶ routine for connection initialization
-
keepalive
(connection)¶ routine executed when there has been a long time since last data arrival. Check if the connection is down.
-
parse
(connection, data, laststart)¶ Parse input data into events
Parameters: - connection – connection object
- data – view for input data
- laststart – last parsed position
Returns: (events, keep) where events are parsed events to send, keep is the unused data length to be keeped for next parse.

querymultipart
(request, connection, container=None, raiseonerror=True)¶ Send a multipart request, wait for all the responses. Return a list of reply messages
-
querywithreply

(connection)¶ routine for reconnect
-
replymatcher
(request, connection, iserror=None)¶ Create an event matcher to match a reply to this request
-
