Constructor Detail

AirControl

public AirControl(Parameters parameters,
                  java.util.ArrayList[] arcPoints)

AirControl constructor.

Parameters:

parameters - Instance of Parameters

arcPoints - Arc points of Graph.

Method Detail

addPlane

private void addPlane()

Creates a plane or planes for the AirControl.

closestMergePoint

private TreeNode closestMergePoint(Plane plane,
                                   int arc)

Find the closest merge point to Plane.

Parameters:

plane - Plane that we are finding closest TreeNode

arc - Number of arc where to look from

Returns:

treeNode that was found

closestTNToPlane

private TreeNode closestTNToPlane(Plane plane)

Find closest TreeNode to Plane.

Parameters:

plane - Plane to calculate closest TreeNode

Returns:

TreeNode Target TreeNode to Plane.

controlPlanes

private void controlPlanes()

Controls planes. This is called from update(). Creates Planes, gives Planes new paths to follow if needed, tells Planes to fly and checks if two Planes are too close to each other. Also removes Planes when they arrive at airport.

flyPlane

private boolean flyPlane(Plane plane)

Calculates distance to travel and the tells Plane to fly it. Also sets Planes direction.

Parameters:

plane - Plane to fly.

Returns:

boolean True if Plane arrives to airport.

getAirportStatus

public boolean getAirportStatus()

Returns airport status.

Returns:

boolean true if airport is open

getArrivedPlanes

Returns number of Planes that have arrived to airport.

Specified by:

getArrivedPlanes in interface AirControlInterface

Returns:

number of Planes that have landed.

getBuildTree

public final BuildTree getBuildTree()

Returns BuildTree of AirControl.

Returns:
