Package likelihoodDetectionModule.linearAverageSpectra

Class RealBlockAverage

java.lang.Object

likelihoodDetectionModule.linearAverageSpectra.RealBlockAverage

public class RealBlockAverage
extends Object

This is a helper class to compute block averages. The first time processData is called, it creates a block of memory the same length as the data passed to the processData() method. After each call to processData, the user can check the status by calling averageReady(). After an average is computed (averageReady() returns true), no more data will be accepted until you call the average() method to collect the results. The averageTimestamp() and averageAbsBlockIndex() return the timestamp and AbsBlockIndex of the averaged result. The timestamp is that of the first block used in computing the average, FIXME what to do with AbsBlockIndex

RealBlockAverage

public RealBlockAverage(int nAvg)

Method Details

NAvg

public int NAvg()

processData

public boolean processData(long timestamp,
 long startSample,
 ComplexArray complexArray)

Processes a block of data at given timestamp and absolute block index.

Parameters:

timestamp - The timestamp of the input block

complexArray - The complex input data

Returns:

true if the data was processed and is safe to discard, false if there is a pending average to be read, and the input data was not used

averageReady

public boolean averageReady()

averageTimestamp

public long averageTimestamp()

averageStartSample

public long averageStartSample()

average

public double[] average()

Returns the processed average data. Call averageReady() to know when data is ready.

Returns:

The pending average, null if no average is ready
