Function Documentation

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

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 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.

Todo:

TW: I am not able to define the operator >> for enum class type (the implementation works fine for the old enum)

Parameters

value

The value to modify

Returns

A padded string
