MelProcess

public MelProcess(MelControl melControl)

Method Details

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

newData

public void newData(PamObservable o,
 PamDataUnit arg)

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:

sampleRate -

notify - Notify other PamObservers and PamObservables in the chain.

prepareProcess

public void prepareProcess()

Description copied from class: PamProcess

Called for each process before any of them receive the PamStart command

Overrides:

prepareProcess in class PamProcess

prepareProcessOK

public boolean prepareProcessOK()

Description copied from class: PamProcess

New version of prepareProcess which get's called from PAMController prior to PAMGuard starting up. If a single process returns false from this function, startup will be aborted.

For backwards compatibility (to save the need to modify every process) there is a default function which simply calls the older prepareProcess() function, then return true, but processes which might fail can override this and return false instead if they so wish.

Initial motivation for this function was to stop millions of empty files being created when the watchdog is running but the DAQ can't start.

Overrides:

prepareProcessOK in class PamProcess

Returns:

true if it's looking highly likely that the process is going to start OK.

getInputFFTData

public FFTDataBlock getInputFFTData()

Returns:

the inputFFTData
