Parameters:

group -

Method Detail

addSamplingSet

public void addSamplingSet(java.util.ArrayList<DataItem> samp)

Adds a Sampling Set to the array containing some (or all) the data to be printed to file.

Parameters:

samp - Sampling Set (data from one property), to be added to the set of data to be printed to the file.

removeSamplingSets

public void removeSamplingSets()

Re initialize the data, erasing everything.

setHeaderFile

public void setHeaderFile(java.lang.String header)

Sets the header that will be printed at the beginning of the file.

Parameters:

header - Header of the content of the file. Is a resume of the properties.

setFilePrefix

public void setFilePrefix(java.lang.String prefix)

Sets the prefix for the filename. Usually the sampling group name.

Parameters:

prefix -

getFileName

public java.lang.String getFileName()

Returns:

Name of the file which the data will be dumped.

initialize

public void initialize(int freq)

dumpToFile

public void dumpToFile(long frequency)

Start the dumping process.

Parameters:

frequency - Frequency at which the data is to be separated in the printout file.

dumpToFile

public void dumpToFile(long frequency,
                       double prec)

Start the dumping process. This method should only be called if you know what you are doing.
Setting the prec lower will get leaks of data, and setting it higher, will get you duplicated data.

Parameters:

frequency - Frequency at which the data is to be separated in the printout file.

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