public class TLcdLonLatCircleBy3Points
extends ALcd2DEditableShape
implements ILcd2DEditableCircleBy3Points, ILcdCache
```
This class provides an implementation of ILcd2DEditableCircleBy3Points in the geodetic space. In addition to the properties defined by ILcd2DEditableCircleBy3Points, a TLcdLonLatArcBy3Points has an ellipsoid on which it lives.
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.

    Description copied from class: ALcdShape
    
    Creates and returns a copy of this object, by delegating to Object.clone(). Extensions should delegate to this implementation with super.clone(), in order to create an object instance of the right type, with all fields copied. They then should explicitly clone any non-primitive fields for which a deeper clone is required.
    
    Specified by:
    
    clone in interface ILcdCloneable
    
    Overrides:
    
    clone in class ALcdShape
    
    See Also:
    
    Object.clone()
  - equals
```
public boolean equals(Object o)
```
    Description copied from class: ALcdShape
    
    An object is considered equal to this shape if it has the same class. Extensions should refine this comparison, based on their properties.
    
    Overrides:
    
    equals in class ALcdShape
  - hashCode
```
public int hashCode()
```
    Description copied from class: ALcdShape
    
    The hash code of this shape is the hash code of its class, in order to be consistent with the ALcdShape.equals(Object) method. Extensions should refine this implementation, based on their properties.
    
    Overrides:
    
    hashCode in class ALcdShape
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
