\ccDefinition
  
The concept \ccRefName\ describes the requirements for the primitives stored in the AABB data structure. The concept encapsulates a type for the geometric primitives and an identifier type by which those primitives are referred to. The concept \ccRefName\ also refines the concepts DefaultConstructible and Assignable.

\ccTypes

\ccNestedType{Data_type}{The geometric primitive type.}

\ccNestedType{Id_type}{The type of identifiers by which the primitives are referred to.}


\ccCreationVariable{primitive}  %% choose variable name
\ccOperations

%\ccMethod{void foo();}{some member functions}
\ccMethod{Data_type get_data();}
{Returns the geometric data wrapped inside the Primitive.}

\ccMethod{Id_type get_id();}
{Returns the corresponding identifier. This identifier is only used as a representant for the primitive in the output of the \ccc{AABB_tree} methods.}

% \ccHasModels

% \ccc{AABB_primitive_base<ID>}

\ccExample

Usually, the \ccc{Primitive} type is a wrapper around a \ccc{Handle}. Assume for instance, that geometric primitives 
are to be the faces of a mesh stored as a \ccc{CGAL::Polyhedron}, the Primitive type would be a wrapper around the \ccc{Face_handle}  type of the polyhedron. The \ccc{Data_type} would be \ccc{Face},
 the \ccc{Id_type} would be \ccc{Face_handle}, \ccc{get_data()} would dereference the \ccc{Face_handle}, and \ccc{get_id()} would return the \ccc{Face_handle} itself. 

% A short example program.
% Instead of a short program fragment, a full running program can be
% included using the 
% \verb|\ccIncludeExampleCode{Package/AABBPrimitive.C}| 
% macro. The program example would be part of the source code distribution and
% also part of the automatic test suite.
