◆ getData()

template<typename VE , typename SPD = SetPtsData, typename SP = SetPts>
boost::shared_ptr<SPD> MoFEM::FieldEvaluatorInterface::getData ( const double *  ptr = nullptr,
const int  nb_eval_points = 0,
const double  eps = 1e-12,
VERBOSITY_LEVELS  verb = QUIET 
)

Get the Data object.

Pack pointers with data structures for field evaluator and finite element. Function return shared pointer if returned shared pointer is reset; all data are destroyed. The idea is to pack all data in one structure, create shared pointer to it and return aliased shared pointer to one of the elements of the data structure. It is a bit complicated, but has great flexibility.

Template Parameters
VE
SetPtsData
SetPts
Parameters
ptr
nb_eval_points
eps
verb
Returns
