Method Summary

Methods

Modifier and Type	Method and Description
static OFMessage	makeError(OFError.OFBadActionCode code, OFMessage msg) Makes an OpenFlow error message for a bad action and given OpenFlow message.
static OFMessage	makeErrorMsg(OFError.OFBadRequestCode code, OFMessage msg) Makes an OpenFlow error message for a bad request and given OpenFlow message.
static OFMessage	makeErrorMsg(OFError.OFFlowModFailedCode code, OFMessage msg) Makes an OpenFlow error message for a failed flow mod and given OpenFlow message.
static OFMessage	makeErrorMsg(OFError.OFPortModFailedCode code, OFMessage msg) Makes an OpenFlow error message for a failed port mod and given OpenFlow message.
static OVXSwitch	translateXid(OFMessage msg, OVXPort inPort) Xid translation based on port for "accurate" translation with a specific PhysicalSwitch.
static Integer	translateXid(OFMessage msg, OVXSwitch vsw) Xid translation based on OVXSwitch, for cases where port cannot be determined.
static void	translateXidAndSend(OFMessage msg, OVXPort inPort) Translates the Xid of a PhysicalSwitch-bound message and sends it there.
static void	translateXidAndSend(OFMessage msg, OVXSwitch vsw) Translates the Xid of a PhysicalSwitch-bound message and sends it there.
static OVXSwitch	untranslateXid(OFMessage msg, PhysicalSwitch psw) Undoes the XID translation and returns the original virtual switch.
static void	untranslateXidAndSend(OFMessage msg, PhysicalSwitch psw) Undoes the Xid translation and tries to send the resulting message to the origin OVXSwitch.
