Detailed Description

template<typename Output, void(FEMContext::*)(unsigned int, const Point &, Output &, const Real) const point_output>
class libMesh::OldSolutionBase< Output, point_output >

The OldSolutionBase input functor abstract base class is the root of the OldSolutionValue and OldSolutionCoefs classes which allow a GenericProjector to read old solution values or solution interpolation coefficients for a just-refined-and-coarsened mesh.
