Package IshmaelDetector

Class IshDetFnProcess

java.lang.Object

PamguardMVC.PamProcess

IshmaelDetector.IshDetFnProcess

All Implemented Interfaces:

PamObserver, ProcessAnnotator

Direct Known Subclasses:

EnergySumProcess, MatchFiltProcess, MatchFiltProcess2, SgramCorrProcess

public abstract class IshDetFnProcess
extends PamProcess

This is the abstract superclass for all the "Ishmael detectors", i.e., the detection PamProcesses that use a detection function and threshold in the course of doing making detections. Currently this means it is the superclass of EnergySumProcess, SgramCorrProcess, and MatchFiltProcess.

Constructor Details

IshDetFnProcess

public IshDetFnProcess(IshDetControl ishDetControl,
 PamDataBlock parentDataBlock)

Initialiser.

IMPORTANT: The subclass initializer should construct the ishDetParams before calling this.

Parameters:

ishDetControl - -- e.g., an EnergySumControl, SgramCorrControl, etc.

parentDataBlock - -- an FFTDataBlock or RawDataBlock

Method Details

getLongName

public abstract String getLongName()

inputDataClass

public abstract Class inputDataClass()

getDetSampleRate

public abstract float getDetSampleRate()

getChannelMap

public int getChannelMap()

getInputDataBlock

public PamDataBlock getInputDataBlock()

An IshDetFnProcess has one input stream. Return it, or null if it's not available.

setSampleRate

public void setSampleRate(float sampleRate,
 boolean notify)

This is called when the sample rate changes. It also gets called on other occasions, like when the model changes (or the FFT size changes??).

Specified by:

setSampleRate in interface PamObserver

Overrides:

setSampleRate in class PamProcess

Parameters:

notify - Notify other PamObservers and PamObservables in the chain.

setupConnections

public void setupConnections()

getOutputDataUnit

public IshDetFnDataUnit getOutputDataUnit(PamDataUnit rawOrFftDataUnit)

Get a new IshDetDataUnit suitable for holding output data. This code was copied from PamFFTProcess.newData() and modified.

Parameters:

rawOrFftDataUnit - input to the detector process (EnergySumProcess, etc.).

Returns:

a fresh IshDetDataUnit, with time fields and channel bitmap set

prepareProcess

public void prepareProcess()

Get a new IshDetDataUnit suitable for holding output data. This code was copied from PamFFTProcess.newData() and modified.

Overrides:

prepareProcess in class PamProcess

Parameters:

rawDataUnit - input to the detector process (MatchFiltProcess, etc.).

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

getLoFreq

public abstract float getLoFreq()

Returns:

the lowest frequency of the detection - e.g. 0 or the lower bound of the detection kernel

getHiFreq

public abstract float getHiFreq()

Returns:

the highest frequency of the detection - e.g. sampleRate/2 or the upper bound of the detection kernel

getOutputDataBlock

public PamDataBlock getOutputDataBlock()

Get the output data block.

Returns:

the output data block.
