IPAddressDetector

public IPAddressDetector(long interval,
                         NodeIPDetector detector)

Parameters:

interval -

detector -

Method Detail

getCheckpointName

public java.lang.String getCheckpointName()

Returns:

our name

nextCheckpoint

public long nextCheckpoint()

Returns:

next scheduling point

getAddressNoCallback

public java.net.InetAddress[] getAddressNoCallback()

Fetch the currently detected IP address. If not detected yet, run the detection. DO NOT callback to detector.redetectAddresses().

Returns:

getAddress

public java.net.InetAddress[] getAddress(Executor executor)

Fetches the currently detected IP address. If not detected yet a detection is forced. If the IP address list changes, call the callback on the detector, off-thread, using the given Executor. This method is intended to be called by code other than the detector itself.

Returns:

Detected ip addresses

checkpoint

protected boolean checkpoint()

Execute a checkpoint - detect our internet IP address and log it

oldDetect

protected java.net.InetAddress oldDetect()

Returns:

onGetAddresses

protected void onGetAddresses(java.util.List<java.net.InetAddress> addrs)

Do something with the list of detected IP addresses.

Parameters:

addrs - Vector of InetAddresses

run

public void run()

Specified by:

run in interface java.lang.Runnable

clearCached

public void clearCached()
