Detailed Description

Base class for dealing with files.

This class just provides things which are common among OFile and IFile

Constructor & Destructor Documentation

◆ FileBase() [1/2]

PLMD::FileBase::FileBase ( const FileBase & )

privatedelete

Copy constructor is disabled.

◆ FileBase() [2/2]

PLMD::FileBase::FileBase ( )

protected

Private constructor.

In this manner one cannot instantiate a FileBase object

◆ ~FileBase()

PLMD::FileBase::~FileBase ( )

virtual

Virtual destructor (allows inheritance)

Member Function Documentation

◆ appendSuffix()

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

static

Append suffix.

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

◆ close()

void PLMD::FileBase::close ( )

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

◆ enforceSuffix()

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

Enforce suffix.

Overrides the one set in PlumedMain&

◆ FileExist()

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

Check if the file exists.

◆ flush()

FileBase & PLMD::FileBase::flush ( )

virtual

Flushes the file to disk.

Reimplemented in PLMD::OFile.

◆ getFILE()

FILE * PLMD::FileBase::getFILE ( ) const

inline

Get the underlying file pointer.

It might be null even if the file is open, e.g. when the file was open as a gzipped file.

◆ getMode()

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

inline

Retrieve the mode.

◆ getPath()

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

inline

Retrieve the path.

◆ getSuffix()

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

Get the file suffix.

◆ isOpen()

bool PLMD::FileBase::isOpen ( )

Check if a file is open.

◆ link() [1/4]

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

Link to an Action object.

Automatically links also the corresponding PlumedMain and Communicator.

◆ link() [2/4]

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

Link to a Communicator object.

◆ link() [3/4]

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

Link to an already open filed.

◆ link() [4/4]

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

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

◆ open()

virtual FileBase& PLMD::FileBase::open ( const std::string & name )

pure virtual

Opens the file.

Implemented in PLMD::OFile, and PLMD::IFile.

◆ operator bool()

PLMD::FileBase::operator bool ( ) const

Check for error/eof.

◆ operator=()

FileBase& PLMD::FileBase::operator= ( const FileBase & )

privatedelete

Assignment operator is disabled.

◆ setHeavyFlush()

void PLMD::FileBase::setHeavyFlush ( )

inline

Set heavyFlush flag.

Member Data Documentation

◆ action

Action* PLMD::FileBase::action

protected

pointer to corresponding action. NULL if not linked

◆ cloned

bool PLMD::FileBase::cloned

protected

Control closing on destructor.

If true, file will not be closed in destructor

Communicator* PLMD::FileBase::comm

protected

communicator. NULL if not set

◆ enforcedSuffix

std::string PLMD::FileBase::enforcedSuffix

private

Enforced suffix:

◆ enforcedSuffix_

bool PLMD::FileBase::enforcedSuffix_

private

If true, use enforcedSuffix, else get it from PlumedMain.

◆ eof

bool PLMD::FileBase::eof

protected

Set to true when end of file is encountered.

◆ err

bool PLMD::FileBase::err

protected

Set to true when error is encountered.

◆ fp

FILE* PLMD::FileBase::fp

protected

file pointer

◆ gzfp

void* PLMD::FileBase::gzfp

protected

zip file pointer.

◆ heavyFlush

bool PLMD::FileBase::heavyFlush

protected

Set to true if you want flush to be heavy (close/reopen)

◆ mode

std::string PLMD::FileBase::mode

protected

mode of the opened file

◆ path

std::string PLMD::FileBase::path

protected

path of the opened file

◆ plumed

PlumedMain* PLMD::FileBase::plumed

protected

pointer to main plumed object. NULL if not linked
