public class TLcdXYPolypoint
extends ALcd2DEditablePolypoint
implements ILcd2DEditablePolypoint, ILcdCache

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

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.

Makes a clone of the point list that represents the polypoint if it implements the interface ILcdCloneable and aDeepCopy is true. #see com.luciad.util.ILcdCloneable

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. If cloning is not possible, a warning is sent to the log and a shallow copy is returned.

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
