Hi all!
I am trying to register a device in an existing device class, but I am
having trouble getting the pointer to an existing class.
I can create a class in a module, get the pointer to it and then use
it to register the device with:

Hi,
I believe the next code is wrong:
class Egg {
Egg e;
int i;
Egg(int ii=0) : i(ii) {}
};
because you would end up with an endless definition (memory allocation) of Egg objects, thus int i.
Ok, so God Eckel proposes for a singleton:
class Egg {
static Egg e;
int... (5 Replies)

geo_domain_indirect(7rheolef) rheolef-6.1 geo_domain_indirect(7rheolef)
NAME
geo_domain_indirect_rep - a named part of a finite element mesh
DESCRIPTION
The geo_domain_indirect_rep class defines a container for a part of a finite element mesh. This describes the connectivity of edges or
faces. This class is usefull for boundary condition setting.
IMPLEMENTATION NOTE
The geo_domain_indirect_rep class is splitted into two parts. The first one is the domain_indirect class, that contains the main renumber-
ing features: it acts as an indirection on a geo class(see geo(2)). The second one is the geo class itself, named here the background geo.
Thus, the geo_domain_indirect class develops a complete geo-like interface, via the geo_abstract_rep pure virtual class derivation, and can
be used by the space class (see space(2)).
The split between domain_indirect and geo_domain_indirect is necessary, because the geo class contains a list of domain_indirect. The geo
class cannot contains a list of geo_domain_indirect classes, that refers to the geo class itself: a loop in reference counting leads to a
blocking situation in the automatic deallocation.
