PamguardMVC.PamProcess

GPS.ProcessNmeaData

All Implemented Interfaces:

PamObserver, ProcessAnnotator

public class ProcessNmeaData
extends PamProcess

Author:

Doug Gillespie PamProcess that subscribed to the AcquireNmeaData processes output data block, selects just the interesting stuff in the GPRMC string and creates a new data block with the string data unpacked into more usable doubles.

Method Details

firstRequiredTime

public long firstRequiredTime(PamObservable o,
 Object arg)

notifyModelChanged

public void notifyModelChanged(int changeType)

Overrides:

notifyModelChanged in class PamProcess

noteNewSettings

public void noteNewSettings()

Specified by:

noteNewSettings in interface PamObserver

Overrides:

noteNewSettings in class PamProcess

newData

public void newData(PamObservable o,
 PamDataUnit pamData)

Overrides:

newData in class PamProcess

setSampleRate

public void setSampleRate(float sampleRate,
 boolean notify)

Description copied from interface: PamObserver

New sample rate

Specified by:

setSampleRate in interface PamObserver

Overrides:

setSampleRate in class PamProcess

Parameters:

notify - Notify other PamObservers and PamObservables in the chain.

pamStart

public void pamStart()

Description copied from class: PamProcess

Called for each process to tell it to start (may not be necessary for processes which are listening for data anyway).

Specified by:

pamStart in class PamProcess

pamStop

public void pamStop()

Description copied from class: PamProcess

Stops the process.

Specified by:

pamStop in class PamProcess

clearOldData

public void clearOldData()

Description copied from class: PamProcess

Clears all data from all output data blocks of this process.
This gets called from the main controller at the start of operations. Can be overridden in some classes which don't want to delete existing data or they can set the clearAtStart flag in any data block.

Overrides:

clearOldData in class PamProcess

getGpsController

public GPSControl getGpsController()

getGpsDataBlock

public GPSDataBlock getGpsDataBlock()

getGpsLogger

public GpsLogger getGpsLogger()
