LuciadLightspeedClass ALcdVVModel

java.lang.Object

com.luciad.view.vertical.ALcdVVModel

All Implemented Interfaces:

ILcdVVModel

Direct Known Subclasses:

TLcdVVTerrainModel, TLcdVVTerrainProfileModel

public abstract class ALcdVVModel
extends Object
implements ILcdVVModel

This class provides the default implementation of a ILcdVVModel. It shall be used as support class to extend, when implementing the ILcdVVModel interface. Whenever the ILcdVVModel's internal state changes, for example by editing a polyline on a map, the fireChangeEvent has to be called in order to update the VV's internal data-fields and to start repainting the Vertical View.

Method Detail

getDistance

public double getDistance(int aPointIndexA,
                          int aPointIndexB)

Returns the distance between the given two points. This distance typically determines the X-axis of a VV panel. The distance unit can be meters, degrees, seconds, ...

This implementation computes a distance in degrees along a great circle on the globe. Override this method if the distance is not expressed as a length (for example, you're using time) or if you like to use geodetic, rhumb, or cartesian distances.

Specified by:

getDistance in interface ILcdVVModel

Parameters:

aPointIndexA - the index of the first point on the main profile.

aPointIndexB - the index of the second point on the main profile

Returns:

the distance between the 2 points along a great circle on the globe.

addChangeListener

public void addChangeListener(ChangeListener l)

Description copied from interface: ILcdVVModel

The changeEvent will be thrown when the models internal state has changed and recalculation is required.

Specified by:

addChangeListener in interface ILcdVVModel

removeChangeListener

public void removeChangeListener(ChangeListener l)

Specified by:

removeChangeListener in interface ILcdVVModel

See Also:

ILcdVVModel.addChangeListener(javax.swing.event.ChangeListener)

fireChangeModel

protected void fireChangeModel()

Notifies all listeners that have registered interest for notification on the ChangeEvent. Should be invoked when the model has changed and the TLcdVVJPanel needs to be reconstructed.
