Private Attributes  
Object  object 
A class that can represent the kinds of objects a triangulation is made up of: vertices, lines, quads and hexes.
The class is rather primitive: it only stores a single integer that represents the dimensionality of the object represented. In other words, this class is useful primarily as a way to pass around an object whose data type explains what it does (unlike just passing around an integer), and for providing symbolic names for these objects such as GeometryPrimitive::vertex instead of an integer zero.
Since the ability to identify such objects with the integral dimension of the object represented, this class provides conversion operators to and from unsigned integers.

An enumeration providing symbolic names for the objects that can be represented by this class. The numeric values of these symbolic names equal the geometric dimensionality of the represented objects to make conversion from and to integer variables simpler.
Enumerator  

vertex  A vertex. 
line  A line. 
quad  A quadrilateral. 
hex  A hexahedron. 
Definition at line 425 of file geometry_info.h.
GeometryPrimitive::GeometryPrimitive  (  const Object  object  ) 
Constructor. Initialize the object with the given argument representing a vertex, line, etc.
GeometryPrimitive::GeometryPrimitive  (  const unsigned int  object_dimension  ) 
Constructor. Initialize the object with an integer that should represent the dimensionality of the geometric object in question. This will usually be a number between zero (a vertex) and three (a hexahedron).
GeometryPrimitive::operator unsigned int  (  )  const 
Return the integral dimension of the object currently represented, i.e. zero for a vertex, one for a line, etc.

private 
The object currently represented.
