Detailed Description

a factory for DataArrayWriters

Some types of DataArrayWriters need to communicate data sauch as byte counts between different instances which write to the same stream. This factory will manage that data.

Constructor & Destructor Documentation

DataArrayWriterFactory()

Dune::VTK::DataArrayWriterFactory::DataArrayWriterFactory ( OutputType  type_, std::ostream &  stream_  )

inline

create a DataArrayWriterFactory

Parameters

type_	Type of DataArrayWriters to create
stream_	The stream that the DataArrayWriters will write to.

Better avoid having multiple active factories on the same stream at the same time. Having an inactive factory (one whose make() method is not called anymore before destruction) around at the same time as an active one should be OK however.

Member Function Documentation

beginAppended()

bool Dune::VTK::DataArrayWriterFactory::beginAppended ( )

inline

signal start of the appended section

This method should be called after the main section has been written, but before the appended section has been started. After this method has been called, a call to make will produce DataArrayWriters suitable for the appended section. The return value of this method signals whether a appended section should be written at all: true means write an appended section, false means don't write an appended section. If an appended section is not needed, the method make() may not be called after a call to this method.

make()

template<typename T >

DataArrayWriter< T > * Dune::VTK::DataArrayWriterFactory::make ( const std::string &  name, unsigned  ncomps, unsigned  nitems, const Indent &  indent  )

inline

create a DataArrayWriter

Template Parameters

T	Type of the data to write.

Parameters

name	Name of the array to write.
ncomps	Number of components of the vectors in to array.
nitems	Number of vectors in the array.
indent	Indentation to use. This is use as-is for the header and trailer lines, but increase by one level for the actual data.

The should never be more than one DataArrayWriter on the same stream around. The returned object should be freed with delete.
