Method Details

setTrackingDataSource

public void setTrackingDataSource(AbstractTrackingDataSource source)

restartMeasurements

public void restartMeasurements()

Restarts all measurements: resets the internal list of tools.

getDataManager

public TrackingDataManager getDataManager()

setDataManager

public void setDataManager(TrackingDataManager dataManager)

getToolByName

public Tool getToolByName(String name)
                   throws Exception

This method checks if the tool exists. A for-loop is used to go through the list of tools of type ToolMeasure. If the name of the searched tool is the same as in the list then the tool will be returned, if there is no tool with the name, the exception is thrown.

Returns:

toolMeasure - of type ToolMeasure

Throws:

Exception - if tool is not found

getAverageMeasurement

public AverageMeasurement getAverageMeasurement(String name)
                                         throws Exception

This method checks if the tool exists and returns the average measurement of all collected data of that tool

Returns:

average measurement of that tool

Throws:

Exception - an exception if the tool was not found

loadNextData

public List<Tool> loadNextData(int countToGetNext)

The method loadNextData gets a number of how much data should be reloaded. In a loop the tools of DataMangager are brought. A list of measurements is created. AverageMeasurment is called and calculated. LoadNextData calls different methods and computes them. The results are added to average Measurement..

Parameters:

countToGetNext - - number of the reloaded data

Returns:

dataManager.getToolMeasures() - list of tools of type ToolMesure

loadNextData

public List<Tool> loadNextData(int countToGetNext,
 boolean updateSource)
