Class SamplingDataCorrelator

java.lang.Object

cl.utfsm.samplingSystemUI.SamplingDataCorrelator

public class SamplingDataCorrelator
extends java.lang.Object

This class correlates various sampling sets through time, and outputs them in a nicely csv file. This class takes various Sampling Data file outputs, which are passed through the addSamplingSet method. Once finished adding Sampling Set, just call the dumpToFile method, and the data will be correlated. Please notice that the usage of memory is minimal and has to be kept whis way.

Constructor Detail

SamplingDataCorrelator

public SamplingDataCorrelator(java.lang.String group,
                              long frequency,
                              java.util.Date startTimestamp)

Default constructor, takes the parameters, stores them, and creates the filename.

Parameters:

group - The name of the Sampling Group to which the data belongs to.

frequency - The Frequency at which the data was sampled.

startTimestamp - At which time that sampling process started.

Method Detail

addSamplingSet

public void addSamplingSet(java.lang.String filename)

Registers a Sampling Set, and read the first line, obtaining the component and the property which sampled.

Parameters:

filaname - Name of the file in which the data for this Sampling Set was dumped.

dumpToFile

public void dumpToFile()

Start the Correlation and Dumping to File process.

dumpToFile

public void dumpToFile(double prec)

Starts the correlation process. This method should only be called if you know what you are doing.
Setting the prec lower or higher will get you leaks of data.

Parameters:

prec - How much of the Frequency will each entry take as a valid interval of time to look forward and backward for data.

consume

public boolean consume()

Method that consumes one line on every cvs file, storing them on memory.

Returns:

True in case that there remains lines to be consumed, and false in case that no lines remain in every file.

getFilename

public java.lang.String getFilename()
