Member Function Documentation

detectMesh()

void TNL::Meshes::Readers::VTKReader::detectMesh ( )

inlineoverridevirtual

Main method responsible for reading the mesh file.

The implementation has to set all protected attributes of this class such that the mesh representation can be loaded into the mesh object by the loadMesh method.

Implements TNL::Meshes::Readers::MeshReader.

readCellData()

VariantVector TNL::Meshes::Readers::VTKReader::readCellData ( const std::string & arrayName ) const

inlinenodiscardoverridevirtual

Reimplemented from TNL::Meshes::Readers::MeshReader.

readPointData()

VariantVector TNL::Meshes::Readers::VTKReader::readPointData ( const std::string & arrayName ) const

inlinenodiscardoverridevirtual

Reimplemented from TNL::Meshes::Readers::MeshReader.

reset()

void TNL::Meshes::Readers::VTKReader::reset ( )

inlineoverridevirtual

This method resets the reader to an empty state.

In particular, implementations should call the resetBase method to reset the arrays holding the intermediate mesh representation.

Reimplemented from TNL::Meshes::Readers::MeshReader.
