Detailed Description

Class containing the log stream.

It is similar to a FILE stream. It allows a printf() function, and also to write with a << operator. Moreover, it can prefix lines with the "PLUMED:" prefix, useful to grep out plumed log from output

Member Function Documentation

OFile & PLMD::OFile::addConstantField ( const std::string & name )

inherited

std::string PLMD::FileBase::appendSuffix	(	const std::string &	path,
		const std::string &	suffix
	)

staticprotectedinherited

Append suffix.

It appends the desired suffix to the string. Notice that it conserves a possible ".gz" suffix.

void PLMD::OFile::backupAllFiles ( const std::string & str )

inherited

This backs up all the files that would have been created with the name str.

It is used in analysis when you are not restarting. Analysis output files at different times, which are names analysis.0.<filename>, analysis.1.<filename> and <filename>, are backed up to bck.0.analysis.0.<filename>, bck.0.analysis.1.<filename> and bck.0.<filename>

void PLMD::OFile::backupFile	(	const std::string &	bstring,
		const std::string &	fname
	)

inherited

Backup a file by giving it a different name.

OFile & PLMD::OFile::clearFields ( )

inherited

Resets the list of fields.

As it is only possible to add new constant fields (addConstantField()), this method can be used to clean the field list.

void PLMD::FileBase::close ( )

inherited

Closes the file Should be used only for explicitely opened files.

OFile & PLMD::OFile::enforceRestart ( )

inherited

Enforce restart, also if the attached plume object is not restarting.

Useful for tests

bool PLMD::FileBase::FileExist ( const std::string & path )

inherited

Check if the file exists.

FileBase & PLMD::OFile::flush ( )

virtualinherited

Flush a file.

Reimplemented from PLMD::FileBase.

OFile & PLMD::OFile::fmtField ( const std::string & fmt )

inherited

Set the format for writing double precision fields.

OFile & PLMD::OFile::fmtField ( )

inherited

Reset the format for writing double precision fields to its default.

bool PLMD::FileBase::isOpen ( )

inherited

Check if a file is open.

FileBase & PLMD::FileBase::link ( FILE * fp )

inherited

Link to an already open filed.

FileBase & PLMD::FileBase::link ( PlumedMain & plumed )

inherited

Link to a PlumedMain object Automatically links also the corresponding Communicator.

FileBase & PLMD::FileBase::link ( Communicator & comm )

inherited

Link to a Communicator object.

FileBase & PLMD::FileBase::link ( Action & action )

inherited

Link to an Action object.

Automatically links also the corresponding PlumedMain and Communicator.

OFile & PLMD::OFile::link ( OFile & l )

inherited

Allows linking this OFile to another one.

In this way, everything written to this OFile will be immediately written on the linked OFile. Notice that a OFile should be either opened explicitly, linked to a FILE or linked to a OFile

OFile & PLMD::OFile::open ( const std::string & name )

virtualinherited

Opens the file using automatic append/backup.

Implements PLMD::FileBase.

PLMD::FileBase::operator bool ( ) const

inherited

Check for error/eof.

int PLMD::OFile::printf	(	const char *	fmt,
			...
	)

inherited

Formatted output with explicit format - a la printf.

OFile & PLMD::OFile::printField	(	const std::string &	name,
		double	v
	)

inherited

Set the value of a double precision field.

OFile & PLMD::OFile::printField	(	const std::string &	name,
		int	v
	)

inherited

Set the value of a int field.

OFile & PLMD::OFile::printField	(	const std::string &	name,
		const std::string &	v
	)

inherited

Set the value of a string field.

OFile & PLMD::OFile::printField	(	Value *	val,
		const double &	v
	)

inherited

Print a value.

OFile & PLMD::OFile::printField ( )

inherited

Close a line.

Typically used as

  of.printField("a",a).printField("b",b).printField();

OFile & PLMD::OFile::rewind ( )

inherited

Rewind a file.

void PLMD::OFile::setBackupString ( const std::string & str )

inherited

Set the string name to be used for automatic backup.

void PLMD::FileBase::setHeavyFlush ( )

inlineinherited

Set heavyFlush flag.

OFile & PLMD::OFile::setLinePrefix ( const std::string & l )

inherited

Set the prefix for output.

Typically "PLUMED: ". Notice that lines with a prefix cannot be parsed using fields in a IFile.

OFile & PLMD::OFile::setupPrintValue ( Value * val )

inherited

Used to setup printing of values.

void PLMD::FileBase::test ( )

staticinherited

Runs a small testcase.
