FileType

enum FileType : unsigned char

strong

With FileType options, one is able to choose if data is to be read/written from/into no or single or multiple files.

Enumerator
NO_FILE	file will not be created/read
ONE_FILE	all data will be written into/ read from a single file called name_
MULTIPLE_FILES	each time-step will be written into/read from separate files numbered consecutively: name_.0, name_.1, .. so on
MULTIPLE_FILES_PADDED	each time-step will be written into/read from separate files numbered consecutively, with numbers padded by zeros to a minimum of four digits: name_.0000, name_.0001, ..

{
            NO_FILE = 0,
            ONE_FILE = 1,
            MULTIPLE_FILES = 2,
            MULTIPLE_FILES_PADDED = 3
};

Function Documentation

operator<<()

std::ostream& operator<<	(	std::ostream &	os,
		FileType	fileType
	)

Writes the FileType as a human-readable string into the output stream 'os'.

Parameters

[in,out]	os	output stream to which the fileType is written
[in]	fileType	the fileType that has to be written to the output stream

Returns

the output stream "os" that is returned after adding the fileType string

{
    if (fileType == FileType::NO_FILE)
        os << "NO_FILE";
    else if (fileType == FileType::ONE_FILE)
        os << "ONE_FILE";
    else if (fileType == FileType::MULTIPLE_FILES)
        os << "MULTIPLE_FILES";
    else if (fileType == FileType::MULTIPLE_FILES_PADDED)
        os << "MULTIPLE_FILES_PADDED";
    else
    {
        logger(ERROR, "FileType not recognized");
    }
    return os;
}

operator>>()

std::istream& operator>>	(	std::istream &	is,
		FileType &	fileType
	)

Reads the FileType from an input stream 'is'.

Parameters

[in,out]	is	The input stream from which the fileType is read
[in]	fileType	The fileType that has to be read from the input stream

Returns

the input stream "is" (that is returned after the fileType string is read out)

{
    std::string fileTypeString;
    is >> fileTypeString;
    if (!fileTypeString.compare("NO_FILE"))
        fileType = FileType::NO_FILE;
    else if (!fileTypeString.compare("ONE_FILE"))
        fileType = FileType::ONE_FILE;
    else if (!fileTypeString.compare("MULTIPLE_FILES"))
        fileType = FileType::MULTIPLE_FILES;
    else if (!fileTypeString.compare("MULTIPLE_FILES_PADDED"))
        fileType = FileType::MULTIPLE_FILES_PADDED;
    else
    {
        logger(ERROR, "operator>>: FileType % not recognized", fileTypeString);
    }
    return is;
}

to_string_padded()

std::string to_string_padded

(

unsigned int

value

)

Pads the number This function tries to pad the number to 4 digits, which is used when you create multiple files with padded numbers. Any numbers larger than 4 digits return unmodified.

Parameters

value

The value to modify

Returns

A padded string

{
    std::ostringstream out;
    out << std::setw(4) << std::setfill('0') << value;
    return out.str();
}

Variable Documentation

NEVER

const unsigned NEVER = static_cast<const unsigned int>(-1)

Todo:

IFCD: can we make this an int instead of unsigned int, as -1 as an unsigned is not good style?
