  mil.navy.nps.util.DatagramStreamBuffer
      mil.navy.nps.util.DatagramStreamBufferNetscape

All Implemented Interfaces:

java.lang.Runnable

public class DatagramStreamBufferNetscape

extends DatagramStreamBuffer

Field Summary

static boolean	DEBUG
(package private) netscape.security.PrivilegeManager	privilegeManager

Fields inherited from class mil.navy.nps.util.DatagramStreamBuffer

datagramBuffer, datagramPort, datagramSocket, multicastAddress, multicastSocket, readingActive, ttl, usingMulticast

Constructor Summary

DatagramStreamBufferNetscape()
Create a new unicast DSB on an ephemeral port, once picked by the system.

DatagramStreamBufferNetscape(int pDatagramPort)
Unicast constructor just calls correct superclass constructor

DatagramStreamBufferNetscape(java.lang.String pMulticastAddress, int pDatagramPort)
Multicast constructor.

Method Summary

void	dumpProperties() dumpProperties prints out the properties of the JVM and system this code is running on.
void	run() The run method.
void	sendDatagram(java.net.DatagramPacket pDatagram) Enables security, then calls the superclass for the actual send operation.

Constructor Detail

DatagramStreamBufferNetscape

public DatagramStreamBufferNetscape(int pDatagramPort)

Unicast constructor just calls correct superclass constructor

DatagramStreamBufferNetscape

public DatagramStreamBufferNetscape()

Create a new unicast DSB on an ephemeral port, once picked by the system.

DatagramStreamBufferNetscape

public DatagramStreamBufferNetscape(java.lang.String pMulticastAddress,
                                    int pDatagramPort)

Multicast constructor. Enables network access and calls the appropriate superclass constructor. Ugly wart: due to Java requirements, the call to super() has to be made before anything else, including security calls. This results in a failure to join the socket in the superclass. We catch that exception and re-try it in this constructor, after we've made the appropriate security calls. If we fail here, too, we hard-fail.

Method Detail

dumpProperties

public void dumpProperties()

dumpProperties prints out the properties of the JVM and system this code is running on.

run

public void run()

The run method. Enables network access, then calls the superclass for the actual implementation.

Specified by:

run in interface java.lang.Runnable

Overrides:

run in class DatagramStreamBuffer

sendDatagram

public void sendDatagram(java.net.DatagramPacket pDatagram)

Enables security, then calls the superclass for the actual send operation.

Overrides:

sendDatagram in class DatagramStreamBuffer
