Class FileController

java.lang.Object
  filecontroller.FileController

All Implemented Interfaces:

FileInterface

public class FileController
extends java.lang.Object
implements FileInterface

The FileController is a maintain class which handles all other classes in filecontroller -package. FileController returns and updates the actual weather data. The source of weather data depends on WeatherDataType -value, which is defined in Parameter -class. WeatherDataType can be "radar" or "PGM". The first value means that we use real data from FMI's radar, and the second value means that we use user made images. No matter what is the source, the data is returned in WeatherMap -class. FileController class also implements the FileInterface.
