What would you think of a "filter" member for collections, and more.
Say you have this:
class Permissions
class Group
{
dbo::collection<Permission> permissions;
... other things ...
}
class Permission
{
dbo::collection<Group> groups;
std::string name;
.. other things ...
}
Where the link between permissions and groups is many-to-many, and
consider this:
dbo:ptr<Group> g = GroupFromSomewhere();
dbo::ptr<Permission> edit_post =
g->permissions.filter<dbo::ptr<Permission> >("where name =
?").bind("edit_post");
if(edit_post) doEditPost();
And perhaps a contain member function and many others, maybe call
filter query to be consistent or whatever, etc...
