Shared lazy-update state for quadrature function coefficients.
Vector coefficient holding precomputed values of a source vector coefficient at the quadrature points...
void Eval(mfem::Vector &V, mfem::ElementTransformation &T, const mfem::IntegrationPoint &ip) override
Return the stored values at ip, re-projecting the source first if invalidated.
void Refresh()
Project the source coefficient into the quadrature function if invalidated.
mfem::VectorCoefficient & _source
Source coefficient the stored values are projected from.
mfem::QuadratureFunction & _qf
Storage for the projected values, shared with the owning MOOSE object.
void SetTime(mfem::real_t t) override
Set the time for the coefficient, invalidating the stored values unless the update policy is NONE.
void Project(mfem::QuadratureFunction &qf) override
Copy the stored values into qf, re-projecting the source first if invalidated.
