◆ _computeGroups()

void Arcane::ArcaneCasePartitioner::_computeGroups	(	IItemFamily *	current_family,
		IItemFamily *	new_family )

private

Recopy the groups of the current family into the new one.

The principle is as follows:

For each entity type, determine the list of localId() of entities of that type in the original mesh.
From this list, build an array indicating for each localId() of the original mesh its localId() in the new mesh (or NULL_ITEM_LOCAL_ID if the entity is absent).
Iterate through the original groups and build for each the list of entities to add to the new mesh.
