Detailed Description

output stream writing into a single file with the SIONlib (http://www2.fz-juelich.de/jsc/sionlib/)

Note

This stream directly stores the binary representation of the data. The binary representation of the stored data is always that of the current machine. On read the data is converted accordingly on machines with different endianess.

Constructor & Destructor Documentation

SIONlibOutStream()

Dune::Fem::SIONlibOutStream::SIONlibOutStream ( const std::string &  filename, const int  rank, MPICommunicatorType  mpiComm, ParameterReader  parameter = Parameter::container()  )

inline

constructor

Parameters

[in]	filename	name of a global file to write to
[in]	rank	process rank (defaults to MPIManager::rank())
[in]	mpiComm	MPI communicator (defaults to MPIHelper :: getCommunicator() )

Note

The filename must be the same on all ranks.

Member Function Documentation

flush()

void Dune::Fem::StandardOutStream::flush ( )

inlineinherited

flush the stream

By calling the flush method, the user can ensure that the stream is actually transferred (e.g., written to disk)

stream()

std::ostream & Dune::Fem::StandardOutStream::stream ( )

inlineinherited

return reference to internal ostream

Referenced by Dune::Fem::StandardOutStream::StandardOutStream().

writeBool()

void Dune::Fem::StandardOutStream::writeBool ( const bool  value )

inlineinherited

write a bool to the stream

Parameters

[in]

value

value to write to the stream

writeChar()

void Dune::Fem::StandardOutStream::writeChar ( const char  value )

inlineinherited

write a char to the stream

Parameters

[in]

value

value to write to the stream

writeDouble()

void Dune::Fem::StandardOutStream::writeDouble ( const double  value )

inlineinherited

write a double to the stream

Parameters

[in]

value

value to write to the stream

writeFloat()

void Dune::Fem::StandardOutStream::writeFloat ( const float  value )

inlineinherited

write a float to the stream

Parameters

[in]

value

value to write to the stream

writeInt()

void Dune::Fem::StandardOutStream::writeInt ( const int  value )

inlineinherited

write an int to the stream

Parameters

[in]

value

writeSignedInt64()

void Dune::Fem::StandardOutStream::writeSignedInt64 ( int64_t  value )

inlineinherited

write an int64_t to the stream

Parameters

[in]

value

value to write to the stream

writeString()

void Dune::Fem::StandardOutStream::writeString ( const std::string &  s )

inlineinherited

write a string to the stream

Parameters

[in]

s

string to write to the stream

writeUnsignedInt()

void Dune::Fem::StandardOutStream::writeUnsignedInt ( unsigned int  value )

inlineinherited

write an unsigned int to the stream

Parameters

[in]

value

value to write to the stream

writeUnsignedInt64()

void Dune::Fem::StandardOutStream::writeUnsignedInt64 ( uint64_t  value )
