public class TLcdLonLatPolypoint
extends ALcd2DEditablePolypoint
implements ILcd2DEditablePolypoint, ILcdCache

This class provides an implementation of ILcd2DEditablePolypoint in the geodetic space.

All longitude/latitude coordinates are expressed in degrees.

This class is thread-safe for concurrent read-only access of its contents. For read-write access, external locking must be used. Such locking is typically done at the model level.

Note that the ILcd2DEditablePointList representing the actual geometry should provide geodetic points (TLcdLonLatPoint), not cartesian (TLcdXYPoint).

Constructor Detail

TLcdLonLatPolypoint

public TLcdLonLatPolypoint()

Creates a new, empty poly-point.

TLcdLonLatPolypoint

public TLcdLonLatPolypoint(ILcd2DEditablePointList a2DEditablePointList)

Creates a new poly-point backed by the given pointlist.

• The point list and the points therein are not copied, and can be modified by this object
• The point list should contain TLcdLonLatPoints

Parameters:

a2DEditablePointList - the initial points

TLcdLonLatPolypoint

public TLcdLonLatPolypoint(TLcdLonLatPolypoint aPolypoint,
                           boolean aDeepCopy)

Creates a poly-point based on another poly-point.

• When aDeepCopy is true, and the given polypoint has a cloneable pointlist (see ILcdCloneable, for example TLcd2DEditablePointList), the underlying points will be cloned.
• Otherwise, the underlying polypoint is re-used by the new object, and updates affect both objects.

Parameters:

aPolypoint - The object to copy

aDeepCopy - whether to make a copy of the points, if possible

Method Detail

calculateBounds

protected void calculateBounds()

Description copied from class: ALcd2DEditablePolypoint

Computes the bounds of the polypoint. The resulting bounds are stored in fBounds.

Specified by:

calculateBounds in class ALcd2DEditablePolypoint

calculateFocusPoint

protected void calculateFocusPoint()

Description copied from class: ALcd2DEditablePolypoint

Computes the focus point as the center of the bounding box. The resulting point is stored in fFocusPoint.

Overrides:

calculateFocusPoint in class ALcd2DEditablePolypoint

clone

public Object clone()

Creates and returns a copy of this object.

The contained editable points list is cloned.

The cache, the bounds and the focus point are not copied or cloned at all, but recalculated when needed.

Specified by:

clone in interface ILcdCloneable

Overrides:

clone in class ALcd2DEditablePolypoint
