Subject: Updating a little bit the documentation of the C++ layer of the Med Memory
X-Git-Tag: ForV3_2_0bx^0
X-Git-Url: http://git.salome-platform.org/gitweb/?a=commitdiff_plain;h=d279b6b1c95e2ebe6e6a4e52d5165ac881d8a2ca;p=tools%2Fmedcoupling.git

Updating a little bit the documentation of the C++ layer of the Med Memory
as well as the User Guide (OCC inputs). That is the first version.

+\item The listed above methods do not take into account information about

+  full information about cell types, use the same methods with
+  \verb+WithPoly+ postfix:
+\begin{itemize}
+\item use \method{getNumberOfTypesWithPoly} to get the number of
+  geometric types for a mesh entity;
+\item use \method{getTypesWithPoly} to get all geometric types for a mesh entity;
+\item use \method{getNumberOfElementsWithPoly} to get the number of cells;
+\item use \method{getElementTypeWithPoly} to get the geometric type of
+  one element.
+\end{itemize}
+There are separate methods to get number of polygons and polyhedrons:
+\method{getNumberOfPolygons} and \method{getNumberOfPolyhedron}
+
+To get connectivity of polygonal elements, use \method{getPolygonsConnectivity} along with
+\method{getPolygonsConnectivityIndex} (see example \myref{MESHconnectivities.cxx}).
+
+To get nodal connectivity of polyhedral elements, it is necessary use together
+3 methods: \method{getPolyhedronConnectivity}, \method{getPolyhedronFacesIndex}
+and \method{getPolyhedronIndex} (see example \myref{MESHconnectivities.cxx}).
