Constructor Detail

RawPduReceivedSupport

public RawPduReceivedSupport(java.lang.Object src)

The constructor.

Parameters:

src - The source (ListeningContext) of the pdu events when they are fired.

Method Detail

empty

public void empty()

Removes all the listeners.

getListenerCount

public int getListenerCount()

Returns the number of listeners.

Returns:

The number of listeners.

addRawPduListener

public void addRawPduListener(RawPduListener listener)

Adds the specified pdu listener to receive pdus.

removeRawPduListener

public void removeRawPduListener(RawPduListener listener)

Removes the specified pdu listener.

fireRawPduReceived

public boolean fireRawPduReceived(int version,
                                  java.lang.String hostAddress,
                                  int hostPort,
                                  byte[] message)

Fires an undecoded pdu event. The event is fired to all listeners, unless one of them consumes it. The idea is that for undecoded pdus it is very unlikely that more than one party (usually SnmpContext objects) is interested.

Parameters:

version - The SNMP version of the pdu

hostAddress - The IP address of the host where the pdu came from

hostPort - The remote port number of the host where the pdu came from

message - The pdu in bytes

Returns:

Whether or not the event has been consumed.
