Detailed Description

template<typename TDomain, typename TErrEstData>
class ug::MultipleErrEstData< TDomain, TErrEstData >

Error estimator data class for discretizations with more than one unknown.

This class is a kind of wrapper for a bundle of error estimator objects. It can be useful if a discretization depends on more than one unknown and needs to compute error estimators for both of them: One can only pass one error estimator to any ElemDisc, but at the same time it is necessary to calculate the errors for different unknowns separately!

This class will not actually do anything, but pass any request on to the underlying objects. As they most probably figure in some other ElemDisc of their corresponding unknown, the considerMe property is set to false by default.

Make sure that the error estimation routines of any elem disc that is given this MultipleErrEstData object write to the correct sub-objects (i.e. ErrEstData objects)! There has to be some kind of mapping between the unknowns of the elem disc and the order in which the single-function ErrEstData objects are added to this object. This will typically be the exact same order. So try not to add the same object of MultipleErrEstData to elem discs with unknowns defined in a different order!

The template parameter TErrEstData must implement the IErrEstData interface.

Todo:: Maybe find a better way to deal with the orders of ErrEstData objects here and unknowns in the elem discs.
