Member Function Documentation

void ParallelColumnDataWriter::AdvanceAlongUnlimitedDimension ( ) [virtual]

Advance along the unlimited dimension. Normally this will be called when all variables in a row have been input.

Reimplemented from ColumnDataWriter.

Definition at line 152 of file ParallelColumnDataWriter.cpp.

References PetscTools::AmMaster(), PetscTools::Barrier(), and ColumnDataWriter::DoAdvanceAlongUnlimitedDimension().

void ParallelColumnDataWriter::Close ( ) [virtual]

Close any open files.

Reimplemented from ColumnDataWriter.

Definition at line 163 of file ParallelColumnDataWriter.cpp.

References PetscTools::AmMaster(), and PetscTools::Barrier().

void ParallelColumnDataWriter::EndDefineMode ( ) [virtual]

End the define mode of the DataWriter.

Reimplemented from ColumnDataWriter.

Definition at line 113 of file ParallelColumnDataWriter.cpp.

References PetscTools::AmMaster(), and ColumnDataWriter::mIsInDefineMode.

void ParallelColumnDataWriter::PutVariable	(	int	variableID,
		double	variableValue,
		long	dimensionPosition = `-1`
	)			`[virtual]`

Input the variable value to the output file or ancillary file

Parameters:

	variableID
	variableValue
	dimensionPosition	The position in column (defaults to -1). This is required if there is a fixed dimension, and will be the position along that dimension

There are two ways of calling PutVariable: 1) All processes call it as a collective operation from the user's code. This only makes sense if they are writing the unlimited dimension (time) variable. It is actually a no-op if any non-master process attempts to write anything at all. 2) The master calls the equivalent method in the parent class after concentrating the data into a single Vec (ie. from the method PutVector() above).

Reimplemented from ColumnDataWriter.
