Detailed Description

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.

Member Function Documentation

void cl.utfsm.samplingSystemUI.SamplingDataCorrelator.addSamplingSet

(

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.

boolean cl.utfsm.samplingSystemUI.SamplingDataCorrelator.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.

void cl.utfsm.samplingSystemUI.SamplingDataCorrelator.dumpToFile

(

)

Start the Correlation and Dumping to File process.

void cl.utfsm.samplingSystemUI.SamplingDataCorrelator.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.
