Detailed Description

Class used to read/send single OpenFlow message from/to an open socket.

Introspection did not find any typical Config paths.

The TCP socket receive callback is connected to the Recv () method, which is responsible for reading the correct number of bytes of a complete OpenFlow message. When the OpenFlow message is completely received, it is sent to the connected callback that was previously set using the SetReceiveCallback () method. On the other direction, the TCP socket send callback is connected to the Send () method that forwards OpenFlow message received by the SendMessage () method to the open socket, respecting the original order of the messages.


No Attributes are defined for this type.
No TraceSources are defined for this type.
Size of this type is 144 bytes (on a 64-bit architecture).
