40 * This class is abstract and not instanciable.
41 * ParaMEDMEM::MEDCouplingUMesh class inherits from this class.
42 * This class aggregates an array '_coords' containing nodes coordinates.
43 * So all operations on coordinates are managed by this class.
44 * This is the case for example for following methods :
45 * rotation, translation, scaling, getNodeIdsNearPoint, boundingbox...
