Constructor & Destructor Documentation

§ DataEntry() [1/2]

template<typename DoFHandlerType , typename VectorType >
internal::DataOut::DataEntry< DoFHandlerType, VectorType >::DataEntry ( const DoFHandlerType *  dofs,
const VectorType *  data,
const std::vector< std::string > &  names,
const std::vector< DataComponentInterpretation::DataComponentInterpretation > &  data_component_interpretation 
)

Constructor. Give a list of names for the individual components of the vector and their interpretation as scalar or vector data. This constructor assumes that no postprocessor is going to be used.

Definition at line 498 of file data_out_dof_data.cc.

§ DataEntry() [2/2]

template<typename DoFHandlerType , typename VectorType >
internal::DataOut::DataEntry< DoFHandlerType, VectorType >::DataEntry ( const DoFHandlerType *  dofs,
const VectorType *  data,
const DataPostprocessor< DoFHandlerType::space_dimension > *  data_postprocessor 
)

Constructor when a data postprocessor is going to be used. In that case, the names and vector declarations are going to be acquired from the postprocessor.

Definition at line 511 of file data_out_dof_data.cc.

§ get_cell_data_value()

template<typename DoFHandlerType , typename VectorType >
double internal::DataOut::DataEntry< DoFHandlerType, VectorType >::get_cell_data_value ( const unsigned int  cell_number) const
virtual

Assuming that the stored vector is a cell vector, extract the given element from it.

Implements internal::DataOut::DataEntryBase< DoFHandlerType >.

Definition at line 544 of file data_out_dof_data.cc.

§ get_function_values() [1/2]

template<typename DoFHandlerType , typename VectorType >
void internal::DataOut::DataEntry< DoFHandlerType, VectorType >::get_function_values ( const FEValuesBase< DoFHandlerType::dimension, DoFHandlerType::space_dimension > &  fe_patch_values,
std::vector< double > &  patch_values 
) const
virtual

Given a FEValuesBase object, extract the values on the present cell from the vector we actually store.

Implements internal::DataOut::DataEntryBase< DoFHandlerType >.

§ get_function_values() [2/2]

template<typename DoFHandlerType , typename VectorType >
