\begin{ccRefClass}{Data_access<Map>} %% add template arg's if necessary
\ccDefinition
The struct \ccRefName\ implements a functor that allows to retrieve
data from an associative container. The functor keeps a reference to
the container. Given an instance of the container's key type, it
returns a pair of the container's value type and a boolean indicating
whether the retrieval was successful.\\
This class can be used to provide the values and gradients of the
interpolation functions.
\ccInclude{CGAL/interpolation_functions.h}
\ccParameters The class
\ccRefName\ has the container type \ccc{Map} as template parameter.
\ccTypes
\ccTypedef{typedef Map::mapped_type Data_type;}{}
\ccGlue
\ccTypedef{typedef Map::key_type Key_type;}{}
\ccCreation
\ccCreationVariable{data_access} %% choose variable name
\ccConstructor{Data_acces(const Map& map);}
{Introduces a \ccc{Data_access} to the container \ccc{map}.}
\ccMethod{std::pair< Data_type, bool> operator()(const Key_type& p);} {If
there is an entry for \ccc{p} in the container \ccc{map}, then the
pair of \ccc{map.find(p)} and \ccc{true} is returned. Otherwise, the
boolean value of the pair is \ccc{false}.}
