[odb-users] Re:Problem with object loading view

[Andrew Cunningham]

Boris,

Every C++ OODB I am familiar with uses that "pattern" where an object is
loaded automatically by the use of the -> or (*) operators. For example,
Versant, Objectivity. I think what Marcel was saying was that having to
manually manage the load'ing of lazy_ptrs is fine for simple examples, but
for a complex C++ object model it just becomes too much of a burden. Using
-> to load means you really have no idea when the object is loaded, and
that's a good thing!

I could contribute my work, but I created a specialization of my own
intrusive reference counted shared pointer type - very specific to my use
case.
