public class TLcdXYPoint extends ALcd2DEditablePoint implements ILcd2DEditablePoint
This class provides an implementation of ILcd2DEditablePoint 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.

Use as a domain object

If you plan on using TLcdXYPoint as a domain object (e.g. using ILcdModel.addElement), please note that two TLcdXYPoint instances are considered to be equal if they describe the same location. If location does not uniquely identify your domain objects, please override equals/hashcode to take the additional properties into account. Alternatively, one could consider every class instance different, resulting in these equals/hashcode implementations: 

  public boolean equals( Object aObject ) {
    return aObject == this;
  }

  public int hashCode() {
    return System.identityHashCode( this );
  }
Failing to respect equals/hashcode may result in undesired behavior, for example when performing spatial queries, used during painting.
