- * Interface class for creation of a link between two
- * processor groups for exhanging mesh or field data.
- * The \c DEC is defined by attaching a field on the receiving or on the
- * sending side.
- * On top of attaching a \c ParaMEDMEM::FIELD, it is possible to
- * attach a ICoCo::Field. This class is an abstract class that enables
- * coupling of codes that respect the ICoCo interface \ref icoco. It has two implementations:
- * one for codes that express their fields as \ref medoupling fields (ICoCo::MEDField) and one
- * for codes that express their fields as Trio/U fields.

- dec.attachLocalField(field);
- dec.synchronize();
