Method Detail

getKeepAliveTimerValue

public final Integer getKeepAliveTimerValue()

getDeadTimerValue

public final Integer getDeadTimerValue()

sendMessage

public io.netty.util.concurrent.Future<Void> sendMessage(org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.pcep.types.rev131005.Message msg)

Sends message to serialization.

Specified by:

sendMessage in interface org.opendaylight.protocol.pcep.PCEPSession

Parameters:

msg - to be sent

isClosed

public boolean isClosed()

close

public void close()

Closes PCEP session without sending a Close message, as the channel is no longer active.

Specified by:

close in interface AutoCloseable

close

public void close(org.opendaylight.protocol.pcep.TerminationReason reason)

Closes PCEP session, cancels all timers, returns to state Idle, sends the Close Message. KeepAlive and DeadTimer are cancelled if the state of the session changes to IDLE. This method is used to close the PCEP session from inside the session or from the listener, therefore the parent of this session should be informed.

Specified by:

close in interface org.opendaylight.protocol.pcep.PCEPSession

getRemoteTlvs

public org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.pcep.types.rev131005.open.object.open.Tlvs getRemoteTlvs()

Specified by:

getRemoteTlvs in interface org.opendaylight.protocol.pcep.PCEPSession

getRemoteAddress

public InetAddress getRemoteAddress()

Specified by:

getRemoteAddress in interface org.opendaylight.protocol.pcep.PCEPSession

endOfInput

public void endOfInput()

handleMalformedMessage

public void handleMalformedMessage(org.opendaylight.protocol.pcep.spi.PCEPErrors error)

The fact, that a message is malformed, comes from parser. In case of unrecognized message a particular error is sent (CAPABILITY_NOT_SUPPORTED) and the method checks if the MAX_UNKNOWN_MSG per minute wasn't overstepped. Second, any other error occurred that is specified by rfc. In this case, the an error message is generated and sent.

Parameters:

error - documented error in RFC5440 or draft

handleMessage

public void handleMessage(org.opendaylight.yang.gen.v1.urn.opendaylight.params.xml.ns.yang.pcep.types.rev131005.Message msg)

Handles incoming message. If the session is up, it notifies the user. The user is notified about every message except KeepAlive.

Parameters:

msg - incoming message

toString

public final String toString()

Overrides:

toString in class Object

sessionUp

public void sessionUp()

getUnknownMessagesTimes

protected final Queue<Long> getUnknownMessagesTimes()
