Method Detail

initialize4

public void initialize4()
                 throws Exception

Description copied from interface: Pinger

Initialize IPv4 in this Pinger implementation. If unable to do so, implementations should throw an exception.

Specified by:

initialize4 in interface Pinger

Throws:

Exception

initialize6

public void initialize6()
                 throws Exception

Description copied from interface: Pinger

Initialize IPv6 in this Pinger implementation. If unable to do so, implementations should throw an exception.

Specified by:

initialize6 in interface Pinger

Throws:

Exception

isV4Available

public boolean isV4Available()

Description copied from interface: Pinger

Whether or not IPv4 is initialized and available for this implementation.

Specified by:

isV4Available in interface Pinger

isV6Available

public boolean isV6Available()

Description copied from interface: Pinger

Whether or not IPv6 is initialized and available for this implementation.

Specified by:

isV6Available in interface Pinger

Returns:

ping

public void ping(InetAddress host,
        long timeout,
        int retries,
        int packetsize,
        int sequenceId,
        PingResponseCallback cb)
          throws Exception

ping

Specified by:

ping in interface Pinger

Parameters:

host - a InetAddress object.

timeout - a long.

retries - a int.

packetsize - The size in byte of the ICMP packet.

sequenceId - a short.

cb - a org.opennms.netmgt.icmp.jni.PingResponseCallback object.

Throws:

Exception - if any.

ping

public void ping(InetAddress host,
        long timeout,
        int retries,
        int sequenceId,
        PingResponseCallback cb)
          throws Exception

ping

ping in interface Pinger

Parameters:

host - a InetAddress object.

timeout - a long.

retries - a int.

packetsize - The size in byte of the ICMP packet.

sequenceId - a short.

cb - a org.opennms.netmgt.icmp.jni.PingResponseCallback object.

Throws:

ping

public Number ping(InetAddress host,
          long timeout,
          int retries,
          int packetsize)
            throws Exception

This method is used to ping a remote host to test for ICMP support. If the remote host responds within the specified period, defined by retries and timeouts, then the response time is returned.

Specified by:

ping in interface Pinger

Parameters:

host - The address to poll.

timeout - The time to wait between each retry.

retries - The number of times to retry

packetsize - The size in byte of the ICMP packet.

Returns:

The response time in microseconds if the host is reachable and has responded with an echo reply, otherwise a null value.

Throws:

InterruptedException - if any.

IOException - if any.

Exception - if any.

timeout - The time to wait between each retry.

retries - The number of times to retry

Returns:

The response time in microseconds if the host is reachable and has responded with an echo reply, otherwise a null value.

Throws:

InterruptedException - if any.

IOException - if any.

Exception - if any.
