Function Documentation

operator<<() [1/2]

std::ostream& operator<<	(	std::ostream &	os,
		const File &	o
	)

Parameters

[in,out]	os
[in]	o

Returns

std::ostream& os

{
    o.write(os);
    return os;
}

operator<<() [2/2]

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>>() [1/2]

std::istream& operator>>	(	std::istream &	is,
		File &	o
	)

Parameters

[in,out]	is
[in]	o

Returns

std::istream&

{
    o.read(is);
    return (is);
}

operator>>() [2/2]

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;
}
