Detailed Description

/brief Utility class for managing temporary files.

The TempFile class provides a convenient way to create and manage temporary files. It ensures that the file is deleted upon destruction, unless the user calls retain(true) The class is non-copyable to prevent accidental duplication of file handles.

Note

The path to the temp file is likely different from the supplied file_name

Constructor & Destructor Documentation

TempFile() [1/3]

axom::utilities::filesystem::TempFile::TempFile ( const std::string &  file_name, const std::string &  file_ext = ""  )

explicit

Creates a temp file using file_name and file_ext.

Parameters

file_name	The name of the temporary file to create without extension
file_ext	An optional extension for the temp file

Note

When creating the temp file, the name will likely be changed. You can get the actual file name using the getPath() function after the file is created.

Member Function Documentation

operator=() [1/2]

TempFile& axom::utilities::filesystem::TempFile::operator= ( const TempFile &  )

delete

operator=() [2/2]

TempFile& axom::utilities::filesystem::TempFile::operator= ( TempFile &&  )

delete

retain() [1/2]

void axom::utilities::filesystem::TempFile::retain ( bool  should_retain )

inline

If set to true, we will retain the file after the instance is destroyed.

retain() [2/2]

bool axom::utilities::filesystem::TempFile::retain ( ) const

inline

Returns true if the file will be retained after the instance is destroyed, false otherwise (default)

open()

bool axom::utilities::filesystem::TempFile::open ( std::ios_base::openmode  mode = std::ios::out | std::ios::trunc )

inline

Opens the temporary file for writing.

Parameters

mode	ios flags for opening the file (not used if file is already open)

Returns

true if the file was successfully opened, false otherwise.

close()

void axom::utilities::filesystem::TempFile::close ( )

inline

Closes the temporary file if it is open.

write()

template<typename StringType >

void axom::utilities::filesystem::TempFile::write ( StringType &&  content, std::ios::openmode  mode = std::ios::out | std::ios::trunc, bool  preserve_file_state = true  )

inline

Writes contents to the file

Opens the file if it is not already open using mode and optionally closes the file

Parameters

content	A string to write to the file
mode	The ios mode to open the file
preserve_file_state	Controls whether the file should be closed if we had to open it If false, the file will be left open. If true, it will be left in its initial state

References close(), is_open(), and open().

is_open()

bool axom::utilities::filesystem::TempFile::is_open ( ) const

inline

Checks if the temporary file is currently open.

Returns

true if the file is open, false otherwise.

getPath()

const std::string& axom::utilities::filesystem::TempFile::getPath ( ) const

inline

Returns the path to the temporary file.

getFileContents()

std::string axom::utilities::filesystem::TempFile::getFileContents

(

)

const

Loads the contents of the file into a string and returns it.

operator<<() [1/2]

template<typename T >

TempFile& axom::utilities::filesystem::TempFile::operator<< ( const T &  data )

inline

Overload the << operator to write data to the file (for general types)

operator<<() [2/2]

TempFile& axom::utilities::filesystem::TempFile::operator<< ( std::ostream &(*)(std::ostream &)  manip )

inline

Overload the << operator to support manipulators (e.g., std::endl)
