Constructor Detail

CalculationControl

public CalculationControl(DataCollection dataCollection)

Construct Calculation -package and help classes, which are used when calculating weather, graph and paths for the Graphics -package.

Parameters:

dataCollection - Current instance of dataCollection class.

Method Detail

runTimer

public boolean runTimer()

This method is called from Main-class after all classes are constructed. It loops while flag is set true and keeps program running. With every loop we call update -method, which handles the rest of update -procedures. If update -procedure takes less than we update timer interval says, we put this thread sleep for a specific time.

Specified by:

runTimer in interface CalculationInterface

Returns:

boolean

setTestMode

public void setTestMode()

This method sets the test mode on for JUnit tests.

setTimerFlag

public void setTimerFlag(boolean flag)

Set timer's flag. Program keeps running while flag is true.

Specified by:

setTimerFlag in interface CalculationInterface

Parameters:

flag - Flag value.

startDelay

private void startDelay()

Method pauses this thread for a second. This ensures that graphic's thread get enough computer time.

update

private boolean update()

Method refresh system when thread comes back from sleep. AirSpace and Graphics updates in every round, weather map-, graph- and arrival tree more sparsely. Some calculation can be divided into smaller parts. This optimization is useful when it comes to heavy operations on the same round.

Returns:

succeed
