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

◆ addConstantField()

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

inherited

◆ appendSuffix()

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

staticinherited

Append suffix.

It appends the desired suffix to the string. Notice that it conserves some suffix (e.g. gz/xtc/trr).

◆ backupAllFiles()

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>

◆ backupFile()

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

inherited

Backup a file by giving it a different name.

◆ clearFields()

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.

◆ close()

void PLMD::FileBase::close ( )

inherited

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

◆ enforceBackup()

OFile & PLMD::OFile::enforceBackup ( )

inherited

Enforce backup, even if the attached plumed object is restarting.

◆ enforceRestart()

OFile & PLMD::OFile::enforceRestart ( )

inherited

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

Useful for tests

◆ enforceSuffix()

FileBase & PLMD::FileBase::enforceSuffix ( const std::string & suffix )

inherited

Enforce suffix.

Overrides the one set in PlumedMain&

◆ FileExist()

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

inherited

Check if the file exists.

◆ flush()

FileBase & PLMD::OFile::flush ( )

virtualinherited

Flush a file.

Reimplemented from PLMD::FileBase.

◆ fmtField() [1/2]

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

inherited

Set the format for writing double precision fields.

◆ fmtField() [2/2]

OFile & PLMD::OFile::fmtField ( )

inherited

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

◆ getMode()

std::string PLMD::FileBase::getMode ( ) const

inlineinherited

Retrieve the mode.

◆ getPath()

std::string PLMD::FileBase::getPath ( ) const

inlineinherited

Retrieve the path.

◆ getSuffix()

std::string PLMD::FileBase::getSuffix ( ) const

inherited

Get the file suffix.

◆ isOpen()

bool PLMD::FileBase::isOpen ( )

inherited

Check if a file is open.

◆ link() [1/9]

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

inherited

Link to an already open filed.

◆ link() [2/9]

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

inherited

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

◆ link() [3/9]

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

inherited

Link to a Communicator object.

◆ link() [4/9]

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

inherited

Link to an Action object.

Automatically links also the corresponding PlumedMain and Communicator.

◆ link() [5/9]

FileBase & PLMD::FileBase::link

inherited

Allows overloading of link.

◆ link() [6/9]

FileBase & PLMD::FileBase::link

inherited

Allows overloading of link.

◆ link() [7/9]

FileBase & PLMD::FileBase::link

inherited

Allows overloading of link.

◆ link() [8/9]

◆ link() [9/9]

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

◆ open() [1/2]

virtual FileBase& PLMD::FileBase::open

inherited

Allows overloading of open.

◆ open() [2/2]

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

virtualinherited
