\begin{ccRefConcept}{R}
|
|
|
|
The representation class parameter of the kernel types is denoted by \ccc{R}.
|
|
In terms of concepts, whenever \ccc{R} is used with a class \ccc{Kernel_object_d<R>},
|
|
a model for \ccc{R} must provide a nested type \ccc{R::Kernel_object_d} that conicides
|
|
with \ccc{Kernel_object_d<R>}. The \cgal\ classes \ccc{Cartesian}, \ccc{Homogeneous},
|
|
\ccc{Simple_cartesian} and \ccc{Simple_homogeneous} fulfill this requirement.
|
|
The requirement is slightly
|
|
stronger than the requirements for \ccc{Kernel}, since a type identity between
|
|
\ccc{Kernel::Kernel_object_d} and \ccc{Kernel_object_d<Kernel>} is not required for
|
|
a \ccc{Kernel}. The class \ccc{Kernel_object_d<Kernel>} need not even be instantiable.
