Angle (const Coordinate &pt, double start_angle_in_radials, double angle_in_radials)  
Construct an Angle with a given center, start angle and dimension (both in radians).  
Object *  transform (const Transformation &) const 
Return this Object, transformed by the transformation t.  
Coordinate  attachPoint () const 
Returns a reference point where to attach labels; when this returns an invalidCoord then the attachment is either not done at all, or done in a specific way (like for curves, or for points) The treatment of points could also take advantage of this attachment mechanism.  
Object *  copy () const 
Returns a copy of this Object.  
const double  size () const 
Return the size in radians of this angle.  
const ObjectType *  type () const 
Returns the lowermost ObjectType that this object is an instantiation of.  
const Coordinate  point () const 
Return the center of this angle.  
const double  startAngle () const 
Return the start angle in radians of this angle.  
const double  angle () const 
Return the dimension in radians of this angle.  
bool  equals (const Object &rhs) const 
Returns true if this Object is equal to rhs.

Detailed Description
An Object representing an angle.

Returns a reference point where to attach labels; when this returns an invalidCoord then the attachment is either not done at all, or done in a specific way (like for curves, or for points) The treatment of points could also take advantage of this attachment mechanism. If this method returns a valid Coordinate, then this is interpreted as a pivot point for the label, which can still be moved relative to that point, but follows the object when the object changes. In practice a new RelativePointType is created (position of the string), this type in turn depends on the object (to get its attachPoint) and two DoubleObject that are interpreted as relative displacement (x and y) Implements Object. 

Returns a copy of this Object. The copy is an exact copy. Changes to the copy don't affect the original. Implements Object. 

Returns true if this Object is equal to rhs. This function checks whether rhs is of the same Object type, and whether it contains the same data as this Object. Implements Object. 

Returns the ObjectType representing the Angle type.
Reimplemented from Object. 

Returns the lowermost ObjectType that this object is an instantiation of. E.g. if you want to get a string containing the internal name of the type of an object, you can do:
tn = object.type().internalName() Implements Object.
