Detailed Description

Class interface for writing a file using ISimpleTableReaderWriter. Provides methods for managing parallel writing and name symbols.

This class is, in a way, a wrapper around ISimpleTableReaderWriter, which is quite basic. ISimpleTableWriterHelper is here to simplify the use of ISimpleTableReaderWriter.

In the SimpleTable part, name symbols are keywords surrounded by at signs () that will be replaced by their meaning during execution. In the SimpleTableWriterHelper implementation, there are currently two supported name symbols:

@proc_id@: Will be replaced by the process ID.
@num_procs@: Will be replaced by the number of processes. And in SimpleTableWriterHelper, these symbols are only replaced in the table name.

Member Function Documentation

◆ fileName()

virtual String Arcane::ISimpleTableWriterHelper::fileName ( )

pure virtual

Method to retrieve the file name.

Name symbols have been resolved and the extension is added here.

Returns: String The name.

◆ fileType()

virtual String Arcane::ISimpleTableWriterHelper::fileType ( )

pure virtual

		const String &	table_name,
		const String &	directory_name )

pure virtual

Method to initialize the object. Specifically, the table name and the directory name that will contain the files (the tables directory/directory_name).

Parameters

table_name	The table name (and the output file name).
directory_name	The folder name where the tables will be saved.

◆ internal()

virtual Ref< SimpleTableInternal > Arcane::ISimpleTableWriterHelper::internal ( )

pure virtual

Method to retrieve a reference to the SimpleTableInternal object used.

Returns: Ref<SimpleTableInternal> A copy of the reference.

◆ isFixed()

virtual bool Arcane::ISimpleTableWriterHelper::isFixed ( )

pure virtual

Method to check if the 'std::fixed' flag is active for writing values.

Returns: true If yes.; false If no.

◆ isForcedToUseScientificNotation()

virtual bool Arcane::ISimpleTableWriterHelper::isForcedToUseScientificNotation ( )

pure virtual

Method to check if the 'std::scientific' flag is active for writing values.

Returns: true If yes.; false If no.

◆ isOneFileByRanksPermited()

virtual bool Arcane::ISimpleTableWriterHelper::isOneFileByRanksPermited ( )

pure virtual

Method to check if the parameters currently held by the implementation allow it to write a file per process, especially thanks to name symbols.

Returns: true If yes, the implementation can write a file per process.; false Otherwise, only one file can be written.

◆ outputDirectory()

virtual String Arcane::ISimpleTableWriterHelper::outputDirectory ( )

pure virtual

Method to retrieve the directory name where the tables will be placed.

May be different for each process (depending on the implementation).

Name symbols have been resolved here.

Returns: String The directory.

◆ outputDirectoryWithoutComputation()

virtual String Arcane::ISimpleTableWriterHelper::outputDirectoryWithoutComputation ( )

pure virtual

Method to retrieve the directory name as it was previously provided.

Name symbols are still present here.

Returns: String The directory.

◆ outputPath()

virtual Directory Arcane::ISimpleTableWriterHelper::outputPath ( )

pure virtual

Method to retrieve the path where the tables will be saved.

Example (relative): ./output/csv/[directory_name]/

Returns: String The path.

◆ precision()

virtual Integer Arcane::ISimpleTableWriterHelper::precision ( )

pure virtual

Method to retrieve the precision currently used for writing values.

Returns: Integer The precision.

Referenced by setPrecision().

◆ print()

virtual void Arcane::ISimpleTableWriterHelper::print ( Integer rank = 0 )

pure virtual

Method to display the table.

Parameters

rank	The process ID that should display the table (-1 to signify "all processes").

◆ readerWriter()

virtual Ref< ISimpleTableReaderWriter > Arcane::ISimpleTableWriterHelper::readerWriter ( )

pure virtual

Method to retrieve a reference to the ISimpleTableReaderWriter object used.

Returns: Ref<ISimpleTableReaderWriter> A copy of the reference.

◆ rootPath()

virtual Directory Arcane::ISimpleTableWriterHelper::rootPath ( )

pure virtual

Method to retrieve the path where the implementation saves these tables.

Example (relative): ./output/csv/

Returns: String The path.

◆ setFixed()

virtual void Arcane::ISimpleTableWriterHelper::setFixed ( bool fixed )

pure virtual

Method to set or unset the 'std::fixed' flag.

Applicable to both the 'print()' method and the 'writeFile()' methods.

This flag allows 'forcing' the number of digits after the comma to the desired precision. For example, if 'setPrecision(4)' was called, and 'setFixed(true)' is called, the print of '6.1' will output '6.1000'.

Warning: The "std::fixed" flag modifies the behavior of "setPrecision()"; if the "std::fixed" flag is disabled, the precision defines the total number of digits (before and after the comma); if the "std::fixed" flag is enabled, the precision defines the number of digits after the comma. Be careful when using "std::numeric_limits<Real>::max_digits10" (for writing) or "std::numeric_limits<Real>::digits10" (for reading), which should be used without the "std::fixed" flag.

Parameters

fixed Whether the 'std::fixed' flag should be set or not.

◆ setForcedToUseScientificNotation()

virtual void Arcane::ISimpleTableWriterHelper::setForcedToUseScientificNotation ( bool use_scientific )

pure virtual

Method to set or unset the 'std::scientific' flag.

Applicable to both the 'print()' method and the 'writetable()' method.

This flag allows 'forcing' the display of values in scientific notation.

Parameters

use_scientific Whether the 'std::scientific' flag should be set or not.

◆ setOutputDirectory()

virtual void Arcane::ISimpleTableWriterHelper::setOutputDirectory ( const String & directory )

pure virtual

Method to set the directory where the tables should be saved.

May be different for each process (depending on the implementation).

Parameters

directory The directory.

◆ setPrecision()

virtual void Arcane::ISimpleTableWriterHelper::setPrecision ( Integer precision )

pure virtual

Method to modify the print precision.

Applicable to both the 'print()' method and the 'writeFile()' methods.

Warning: The "std::fixed" flag modifies the behavior of "setPrecision()"; if the "std::fixed" flag is disabled, the precision defines the total number of digits (before and after the comma); if the "std::fixed" flag is enabled, the precision defines the number of digits after the comma. Be careful when using "std::numeric_limits<Real>::max_digits10" (for writing) or "std::numeric_limits<Real>::digits10" (for reading), which should be used without the "std::fixed" flag.

Parameters

precision The new precision.

References precision().

◆ setReaderWriter()

virtual void Arcane::ISimpleTableWriterHelper::setReaderWriter ( const Ref< ISimpleTableReaderWriter > & simple_table_reader_writer )

name The name.

◆ tableName()

virtual String Arcane::ISimpleTableWriterHelper::tableName ( )

pure virtual

Method to retrieve the table name.

May be different for each process (depending on the implementation).

◆ tableNameWithoutComputation()

virtual String Arcane::ISimpleTableWriterHelper::tableNameWithoutComputation ( )

pure virtual

Method to retrieve the table name as it was previously provided.

Name symbols are still present here.

Returns: String The name.

◆ writeFile() [1/2]

virtual bool Arcane::ISimpleTableWriterHelper::writeFile	(	const Directory &	root_directory,
		Integer	rank )

pure virtual

Method to write the table to a file. If rank != -1, processes other than rank return true.

For example, in the SimpleTableWriterHelper implementation, the file(s) will be written in the directory: root_directory/[directory_name]/[table_name].[ISimpleTableReaderWriter.fileType()]

Parameters

root_directory	The root directory where the tables directory should be created.
rank	The process ID that should write the table to a file (-1 to signify "all processes").

Returns: true If the file was written correctly.; false If the file was not written correctly.

◆ writeFile() [2/2]

virtual bool Arcane::ISimpleTableWriterHelper::writeFile ( Integer rank = -1 )

pure virtual

Method to write the table to a file. If rank != -1, processes other than rank return true.

For example, in the SimpleTableWriterHelper implementation, the file(s) will be written in the directory: ./[output]/[directory_name]/[table_name].[ISimpleTableReaderWriter.fileType()]

Parameters

rank	The process ID that should write the table to a file (-1 to signify "all processes").
