public class TLcdXYArc
extends ALcd2DEditableShape
implements ILcd2DEditableArc, ILcdCurve, ILcdCache
```
This class provides an implementation of ILcd2DEditableArc in the cartesian space.
It implements ILcdCache, thus providing a cache to store expensive calculations, e.g. for painters, to store model-world transformations. The cache is cleared whenever the shape is modified.
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.

    The contained center point is cloned.
    The cache is not copied or cloned at all.
    
    Specified by:
    
    clone in interface ILcdCloneable
    
    Overrides:
    
    clone in class ALcdShape
    
    See Also:
    
    Object.clone()
  - equals
```
public boolean equals(Object aObject)
```
    Returns whether the given object has the same class and the same coordinates and parameters.
    
    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
  - getLineSegmentIntersectionCount
```
public int getLineSegmentIntersectionCount(ILcdPoint aP1,
                                           ILcdPoint aP2)
```
    Description copied from interface: ILcdCurve
    
    Returns the number of intersections between this curve and a line segment defined by the two specified points.
    This information can be used to perform containment calculations, if this curve is closed or if this curve is part of a composite closed curve. By determining the number of intersections between this curve and a line segment starting from a given point in a fixed direction, one can determine whether a point is located within the closed curve by using the even-odd rule.
    
    Specified by:
    
    getLineSegmentIntersectionCount in interface ILcdCurve
    
    Parameters:
    
    aP1 - the first point of the line segment
    
    aP2 - the second point of the line segment
    
    Returns:
    
    the number of intersections between the curve and the line segment
