28 A wrapper class that allows you to retrieve non-IOobjects through the
29 object registry. Performs no input or output, simply for a const reference
34 // Your non-IOobject, e.g. Type = scalar
37 // Register it to the object registry
38 IOReferencer<scalar> myIOobject
43 instance, // can be anything
44 [local,] // (optional) can be anything
45 registry, // can be anything
46 IOobject::NO_READ, // *must* be NO_READ
47 IOobject::NO_WRITE // *must* be NO_WRITE
52 // (Now don't let myObject and myIOobject go out of scope)
54 // In another part of your solver, e.g. in a custom boundary condition:
55 const Type& myConstObject = registry.lookupObject<IOReferencer<Type> >
60 // Now you have a local const reference to your non-IOobject
