Package org.opendaylight.openflowplugin.api.openflow.connection

Interface ConnectionContext

All Known Implementing Classes:

ConnectionContextImpl

public interface ConnectionContext

Each OpenFlow session is tracked by a Connection Context. These attach to a particular Device Context in such a way, that there is at most one primary session associated with a Device Context.

Method Detail

setHandshakeContext

void setHandshakeContext(HandshakeContext handshakeContext)

Setter.

Parameters:

handshakeContext - corresponding handshake context used upon this connection

setNodeId

featuresReply - as received from device during handshake

getFeatures

FeaturesReply getFeatures()

Getter.

Returns:

featureReply as received from device during handshake

setDeviceDisconnectedHandler

void setDeviceDisconnectedHandler(DeviceDisconnectedHandler deviceDisconnectedHandler)
