Detailed Description

Conversion of 'Cell' to 'AllEnvCell'.

Instances of this class allow converting a cell Cell into an AllEnvCell cell to obtain material information.

An instance is created via the material manager:

IMeshMaterialMng* mm = ...;

CellToAllEnvCellConverter all_env_cell_converter(mm);

Arcane::Materials::IMeshMaterialMng

Interface for the material and environment manager of a mesh.

Definition core/materials/IMeshMaterialMng.h:58

The creation cost is low, equivalent to a virtual function call. It is therefore not negligible, and it is preferable not to construct an instance inside loops over entities, for example, but outside them.

Once the instance is created, it is then possible to use the [] operator (operator[]()) to perform the conversion:

CellToAllEnvCellConverter all_env_cell_converter(m_material_mng);
Cell cell = ...;
ENUMERATE_FACE(iface,allFaces()){
  Face face = *iface;
  Cell back_cell = face.backCell()
  AllEnvCell back_all_env_cell = all_env_cell_converter[back_cell];
  info() << "nb env=" << back_all_env_cell.nbEnvironment();
}
