Detailed Description

Dump a .vtu/.vtp files contents to a stream.

This will help generating a .vtu/.vtp file. Typical use is like this:

{
  // create writer, writes begin tag
  PVTUWriter writer(std::cout, polyData);
 
  // start the main section
  writer.beginMain();
 
  // dump cell data (optional)
  writer.beginCellData();
  for(each cell data field)
    writer.addArray(field.name, field.ncomps, precision);
  writer.endCellData();
 
  // dump point data (optional)
  writer.beginPointData();
  for(each point data field)
    writer.addArray(field.name, field.ncomps, precision);
  writer.endPointData();
 
  // dump point coordinates
  writer.beginPoints();
  writer.addArray("Coordinates", 3, precision);
  writer.endPoints();
 
  for(each serial piece)
    writer.addPiece(piece.filename);
 
  // finish main section
  writer.endMain();
 
  // end scope so the destructor gets called and the closing tag is written
}

Constructor & Destructor Documentation

PVTUWriter()

Dune::VTK::PVTUWriter::PVTUWriter ( std::ostream &  stream_, FileType  fileType_  )

inline

create a PVTUWriter object

Parameters

stream_	Stream to write to.
fileType_	Whether to write PolyData (1D) or UnstructuredGrid (nD) format.

Create object and write header.

Member Function Documentation

addArray()

void Dune::VTK::PVTUWriter::addArray ( const std::string &  name, unsigned  ncomps, Precision  prec  )

inline

Add an array to the output file.

Template Parameters

T	The datatype of the array.

Parameters

name	Name of the array.
ncomps	Number of components in each vector of the array.
prec	The output precision of the data array

References Dune::VTK::toString().

beginCellData()

void Dune::VTK::PVTUWriter::beginCellData ( const std::string &  scalars = "", const std::string &  vectors = ""  )

inline

start CellData section

Parameters

scalars	Name of field to which should be marked as default scalars field. If this is the empty string, don't set any default.
vectors	Name of field to which should be marked as default vectors field. If this is the empty string, don't set any default.

If there are no CellData fields, the call to this function may be skipped, together with the corresponding call to endCellData().

beginMain()

void Dune::VTK::PVTUWriter::beginMain ( unsigned  ghostLevel = 0 )

inline

start the main PPolyData/PUnstructuredGrid section

Parameters

ghostLevel

Set the GhostLevel attribute

Between the call to this method and to endMain(), there should be calls to add the actual data:

• (optional) beginCellData()/endCellData(),
• (optional) beginPointData()/endPointData(),
• beginPoints()/endPoints(),
• one or more calls to addPiece()

beginPointData()

void Dune::VTK::PVTUWriter::beginPointData ( const std::string &  scalars = "", const std::string &  vectors = ""  )

inline

start PointData section

Parameters

scalars	Name of field to which should be marked as default scalars field. If this is the empty string, don't set any default.
vectors	Name of field to which should be marked as default vectors field. If this is the empty string, don't set any default.

If there are no PointData fields, the call to this function may be skipped, together with the corresponding call to endPointData().

beginPoints()

void Dune::VTK::PVTUWriter::beginPoints ( )

inline

start section for the point coordinates

Between the call to this method an the following call to the endPoints(), there must be a single field written. The name must be "Coordinates" and it must have 3 components.
