Non-nesting implementation of GridFunctionSubSpace.
This is the actual implementation of GridFunctionSubSpace. It is based around the idea of performing the mapping from the subspace to the rootspace in a single step using a SubOrdering. As SubOrderings cannot be nested, this class needs some helper functionality that constructs a new GridFunctionSubSpace directly on top of the underlying root GridFunctionSpace if the user attempts to nest GridFunctionSubSpaces. On the other hand, this implementation should render such usage mostly unnecessary, as it is now possible to directly construct a subspace for a given leaf space. If the compiler has support for template aliases, the de-nesting infrastructure will be able to completely remove all traces of nesting, letting the type obtained by nesting two GridFunctionSubSpaces look exactly like the type obtained by constructing a single GridFunctionSubSpace. Alternatively, without template aliases, it is only possible to have the actual implementation be non-nested. In this case, the Dune::PDELab::GridFunctionSubSpace classes will still nest.

Construct a GridFunctionSubSpace from the storage object of a root space.

Construct a GridFunctionSubSpace from a root space.
|
inlineexplicit |
Construct a GridFunctionSubSpace from the storage of another GridFunctionSubSpace.
This constructor is used to implement the non-nesting behavior by extracting the original root space from the GridFunctionSubSpace and using that space for initialization. In order to work correctly, this relies on a support wrapper that correctly sets up the TreePath for the new space.
