Detailed Description

Class for input files.

This class provides features similar to those in the standard C "FILE*" type, but only for sequential input. See OFile for sequential output.

Constructor & Destructor Documentation

PLMD::IFile::IFile ( )

Constructor.

PLMD::IFile::~IFile ( )

Destructor.

Member Function Documentation

IFile & PLMD::IFile::advanceField ( )

private

Advance to next field (= read one line)

void PLMD::IFile::allowIgnoredFields ( )

Allow some of the fields in the input to be ignored.

void PLMD::IFile::allowNoEOL ( )

Allow files without EOL at the end.

This in practice should be only used when opening plumed input files

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).

void PLMD::FileBase::close ( )

inherited

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

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

inherited

Enforce suffix.

Overrides the one set in PlumedMain&

bool PLMD::IFile::FieldExist ( const std::string & s )

Check if a field exist.

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

inherited

Check if the file exists.

unsigned PLMD::IFile::findField ( const std::string & name ) const

private

Find field index by name.

FileBase & PLMD::FileBase::flush ( )

virtualinherited

Flushes the file to disk.

Reimplemented in PLMD::OFile.

IFile & PLMD::IFile::getline ( std::string & str )

Get a full line as a string.

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

inlineinherited

Retrieve the mode.

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

inlineinherited

Retrieve the path.

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

inherited

Get the file suffix.

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.

size_t PLMD::IFile::llread	(	char *	ptr,
		size_t	s
	)

private

Low-level read.

Note: in parallel, all processes read

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

virtual

Opens the file.

Implements PLMD::FileBase.

PLMD::FileBase::operator bool ( ) const

inherited

Check for error/eof.

void PLMD::IFile::reset ( bool reset )

Reset end of file.

IFile & PLMD::IFile::scanField	(	const std::string &	name,
		double &	x
	)

Read a double field.

IFile & PLMD::IFile::scanField	(	const std::string &	name,
		int &	x
	)

Read a int field.

IFile & PLMD::IFile::scanField	(	const std::string &	name,
		std::string &	str
	)

Read a string field.

IFile & PLMD::IFile::scanField ( )

Ends a field-formatted line.

Typically used as

  if.scanField("a",a).scanField("b",b).scanField();

IFile & PLMD::IFile::scanField ( Value * val )

Read in a value.

IFile & PLMD::IFile::scanFieldList ( std::vector< std::string > & s )

Gets the list of all fields.

void PLMD::FileBase::setHeavyFlush ( )

inlineinherited

Set heavyFlush flag.

void PLMD::FileBase::test ( )

staticinherited

Runs a small testcase.
