Function Documentation

◆ convertLineEndingsToNewLinesOnly()

MLRELEASE_TOOLS_EXPORT std::string ml::ReleaseToolsString::convertLineEndingsToNewLinesOnly ( const std::string & inStr )

Returns a converted inStr where 1) all appearances of "\r\n" and then 2) all appearances of "\r" are replaced with "\n" such that the string is line-ending platform independent and only uses
's.

◆ createIndexList()

MLRELEASE_TOOLS_EXPORT std::vector<size_t> ml::ReleaseToolsString::createIndexList	(	size_t	numIndexes,
		std::string	idxExp,
		std::string &	resultInfo
	)

Creates a list of indexes by parsing the string expression idxExp.

In idxExp the following separators are allowed to separate numbers from each other: "\t", "\n", "\r" and spaces. There is no difference between their meaning.

The following separators can be used to separate different subexpressions: ',' and ';'. There is no difference between there meaning.

All numeric index values used in idxExp must be positive integer-like values (including 0) from within the range [0, numIndexes] or the expression is considered invalid, which means that numIndexes=3 and idxExp"0-5" will be considered invalid.

Parameters

numIndexes	Describes the maximum value of any index in idxExp, larger index values are handled as error. It is also the maximum value for open range specifications such as "3-" which adds the indexes [3, ..., numIndexes] to the result vector.
idxExp	An expression containing index numbers. Examples: "1 7 2" -> 1, 7, 2 "-3" -> 0, 1, 2, 3 "1-4" -> 1, 2, 3, 4 "2-4,1-2" -> 2, 3, 4, 1, 2 At expression end: "3-" -> 3, ..., numIndexes. "" -> returns result vector with no values. Invalid expressions: "1-4-3", "1--3", "-"
resultInfo	Empty on a valid expression, otherwise an error describing the problem.

Returns: The found indexes as std::vector. In error cases successful evaluated subexpressions before commas are returned in the vector. The results of unsuccessfully evaluated subexpressions are undefined.

Warning: By passing a large numIndexes value and idxExp with open ranges such as "2-" the returned vector might become very large. Therefore it is recommended to use the smallest necessary numIndexes values.

◆ endsWith()

MLRELEASE_TOOLS_EXPORT bool ml::ReleaseToolsString::endsWith	(	const std::string &	str,
		const std::string &	endStr
	)

Returns true if str ends with endStr, otherwise false.

◆ makeSingleNewlineTerminated()

MLRELEASE_TOOLS_EXPORT std::string ml::ReleaseToolsString::makeSingleNewlineTerminated ( const std::string & inStr )

Returns inStr + "\n" if inStr does not end neither with "\n" nor with "<br>", otherwise it returns inStr.

◆ removeDuplicates()

MLRELEASE_TOOLS_EXPORT void ml::ReleaseToolsString::removeDuplicates	(	std::string &	strToShrink,
		char	ch = `' '`
	)

Multiple occurrences of ch in strToShrink are reduced to single ones in O(n).

Parameters

strToShrink	The string whose multiple occurrences of ch are condensed to single ones.
ch	The character which is searched in strToShrink and whose multiple occurrences are shrunk to single ones.

◆ removeElements()

MLRELEASE_TOOLS_EXPORT void ml::ReleaseToolsString::removeElements	(	StringVector &	strVec,
		const std::string &	str = `std::string()`
	)

Parameters

taggedStr	The string whose tags are to be replaced.
inImg	The ML paged image from which the information is retrieved to replace the tag values if its pointer is non nullptr and valid; otherwise for the corresponding values defaultTagContent will be used.
inputValues	A vector with a number of strings which are used to replace the placeholders , ... ,; not available vector entries are harmless; defaultTagContent will be used instead.
defaultTagContent	If the value of a tag value cannot be determined then this value will be used instead.
fileType	A string containing the type of the file (if available); the default is empty.
idx	The index of the image if there is any; the defaults is 0.
padSize	Determines the width of the padded values; defaults to 5.

Returns: The string with replaced tag values.

◆ split()

Returns: The vector of sep-separated strings; if sep is empty value is returned in a vector containing one element.

◆ splitAtLineBreaks()

MLRELEASE_TOOLS_EXPORT StringVector ml::ReleaseToolsString::splitAtLineBreaks ( const std::string & value )

Subdivides value at all positions which seem to be a line ending, technically it returns split(convertLineEndingsToNewLinesOnly(value), "\n").

Parameters

value The string to be subdivided at line-breaks.

Returns: The vector of all at-any-line-break-separated strings; if value does not contain any line-break(s) then a one-element vector with value is returned.

◆ terminateWithSingleEndString() [1/2]

MLRELEASE_TOOLS_EXPORT std::string ml::ReleaseToolsString::terminateWithSingleEndString	(	const std::string &	inStr,
		const std::string &	endStr
	)

Returns inStr+endStr if endStr is still not at the end of inStr, otherwise it returns inStr.

◆ terminateWithSingleEndString() [2/2]

MLRELEASE_TOOLS_EXPORT std::string ml::ReleaseToolsString::terminateWithSingleEndString	(	const std::string &	inStr,
		const std::string &	endStr,
		const std::string &	endStr2
	)

Returns inStr + endStr if inStr does not end neither with endStr nor with endStr2, otherwise it returns inStr.

◆ toDblStr()

MLRELEASE_TOOLS_EXPORT std::string ml::ReleaseToolsString::toDblStr	(	MLdouble	val,
		signed char	fieldWidth = `-1`,
		signed char	numDecimalPlaces = `-1`,
		bool	padWithZeros = `false`,
		bool	considerValAsFloat = `false`
	)

Tool function to print an MLdouble value to a std::string.

If numDecimalPlaces > 0 then it is taken as the number of printed digits after the comma (if necessary "0"s are appended). If numDecimalPlaces == 0 then the number is printed without digits after the decimal point and without the decimal point itself. If numDecimalPlaces < 0 the number is printed up to the last available non zero precision digit which can be represented by the data type. If fieldWidth is > 0 then it defines the minimum space provided for the entire string (if necessary then it is left padded with spaces if padWithZeros is false and padded with zeros if padWithZeros), otherwise (if fieldWidth is <=0) it is ignored. If it is necessary to make the number + decimal point + numDecimalPlaces fit into the string the fieldWidth is overridden and implicitly extended. Examples: toDblStr( 3.141500001) -> "3.141500001" toDblStr( 123456789101) -> "123456789101" toDblStr( 333, 3, 5) -> "333.00000" toDblStr(1987321.78, 2, 8) -> "1987321.78000000" toDblStr( 2.6789, 5, 2) -> " 2.68" toDblStr( -17,10, 0) -> " -17" If considerValAsFloat is true then val is handled as if it was a float value instead of a double, thus internally used default digit numbers are not DBL_DIG (15) but FLT_DIG (6).

◆ toIntStr()

MLRELEASE_TOOLS_EXPORT std::string ml::ReleaseToolsString::toIntStr	(	int	val,
		signed char	fieldWidth = `-1`,
		bool	padWithZeros = `false`
	)

Tool function to convert an integer to a string.

If fieldWidth is > 0 and larger than the size of the created number string then the returned string is left padded with spaces if padWithZeros is false and padded with zeros if padWithZeros is true until it reaches the length fieldWidth. If fieldWidth is smaller 0 then the created number string will not have leading spaces nor leading zeros.

◆ toMLIntStr()

MLRELEASE_TOOLS_EXPORT std::string ml::ReleaseToolsString::toMLIntStr	(	MLint	val,
		signed char	fieldWidth = `-1`,
		bool	padWithZeros = `false`
	)

Tool function to convert an MLint to a string.

If fieldWidth is > 0 and larger than the size of the created number string then the returned string is left padded with spaces if padWithZeros is false and padded with zeros if padWithZeros is true until it reaches the length fieldWidth. If fieldWidth is smaller 0 then the created number string will not have leading spaces nor leading zeros.

◆ toMLUIntStr()

MLRELEASE_TOOLS_EXPORT std::string ml::ReleaseToolsString::toMLUIntStr	(	MLuint	val,
		signed char	fieldWidth = `-1`,
		bool	padWithZeros = `false`
	)

Tool function to convert an MLuint to a string.

If fieldWidth is > 0 and larger than the size of the created number string then the returned string is left padded with spaces if padWithZeros is false and padded with zeros if padWithZeros is true until it reaches the length fieldWidth. If fieldWidth is smaller 0 then the created number string will not have leading spaces nor leading zeros.

		signed char	fieldWidth = `-1`,
		bool	padWithZeros = `false`
	)

Tool function to convert a size_t to a string.

If fieldWidth is > 0 and larger than the size of the created number string then the returned string is left padded with spaces if padWithZeros is false and padded with zeros if padWithZeros is true until it reaches the length fieldWidth. If fieldWidth is smaller 0 then the created number string will not have leading spaces nor leading zeros.
