Detailed Description

Function Documentation

trim()

std::string trim

(

const std::string &

orig

)

Returns the string orig without leading and trailing whitespace.

dataToString()

template<typename T >

std::string dataToString

(

const T &

x

)

Returns a string containing the text representation of x. Care is taken that no information is lost in the conversion.

Definition at line 52 of file string_utils.cc.

intToString()

std::string intToString	(	int64	x,
		tsize	width
	)

Returns a string containing the text representation of x, padded with leading zeroes to width characters.

Definition at line 93 of file string_utils.cc.

stringToData() [1/2]

template<typename T >

void stringToData	(	const std::string &	x,
		T &	value
	)

Reads a value of a given datatype from a string

stringToData() [2/2]

template<typename T >

T stringToData ( const std::string &  x )

inline

Reads a value of a given datatype from a string

Definition at line 64 of file string_utils.h.

parse_file()

void parse_file	(	const std::string &	filename,
		std::map< std::string, std::string > &	dict
	)

Parses the file filename and returns the key/value pairs in dict.

equal_nocase()

bool equal_nocase	(	const std::string &	a,
		const std::string &	b
	)

Case-insensitive string comparison Returns true, if a and b differ only in capitalisation, else false.

tolower()

std::string tolower

(

const std::string &

input

)

Returns lowercase version of input.

split() [1/2]

template<typename T >

void split	(	const std::string &	inp,
		std::vector< T > &	list
	)

Tries to split inp into a white-space separated list of values of type T, and appends them to list.

split() [2/2]

template<typename T >

std::vector<T> split ( const std::string &  inp )

inline

Tries to split inp into a white-space separated list of values of type T, and appends them to list.

Definition at line 99 of file string_utils.h.

tokenize() [1/2]

void tokenize	(	const std::string &	inp,
		char	delim,
		std::vector< std::string > &	list
	)

Breaks the string inp into tokens separated by delim, and returns them in list.

tokenize() [2/2]

std::vector<std::string> tokenize ( const std::string &  inp, char  delim  )

inline

Breaks the string inp into tokens separated by delim, and returns them as a vector<string>.

Definition at line 109 of file string_utils.h.

parse_words_from_file()

void parse_words_from_file	(	const std::string &	filename,
		std::vector< std::string > &	words
	)

Reads all white-space separated strings from filename, and returns them in words.
