Detailed Description

A simple C++ string class, used as replacement for std::string.

Member Function Documentation

static bool m2m::String::convert_ascii_to_float	(	const char *	value,
		size_t	size,
		float &	conversion_result
	)

static

Convert ASCII representation to float.

Parameters

value	optionally zero terminated string containing a float value
length	chars to convert, must be more or equal than the chars before zero.
conversion_result	result of conversion

Returns: will be set to true if valid float value is read. If string contain anything else than correctly formated float, false is returned.

static bool m2m::String::convert_ascii_to_int	(	const char *	value,
		size_t	length,
		int64_t &	conversion_result
	)

static

Convert ASCII representation of a base 10 number to int64. This is needed as sscanf("%lld") or atoll() are not universally available.

Parameters

value	optionally zero terminated string containing a zero or one sign char ('+' or '-') and a number in base 10 chars, ie. "0..9"
length	chars to convert, must be more or equal than the chars before zero. This is useful for extracting values from non-zero terminated strings.
conversion_result	result of conversion

Returns: will be set to true if at least one digit is found and a false is returned if: a) no digits found, ie. string is empty b) a non-digit or non-'+' or non-'-' char is found. c) more than one +, - chars are found

Note: the handling of a number with digits in front and non-digits at end (eg. "0zero") differs from sscanf(), as sscanf will return what it got converted and a success value even if the string ended with junk.

void m2m::String::reserve ( size_type n )

Reserve internal string memory so that n characters can be put into the string (plus 1 for the NULL char). If there is already enough memory, nothing happens, if not, the memory is realloated to exactly this amount.

void m2m::String::resize ( size_type n )

Resize string. If n is less than the current size, the string is truncated. If n is larger, the memory is reallocated to exactly this amount, and the additional characters are NULL characters.

void m2m::String::resize	(	size_type	n,
		char	c
	)

Resize string. If n is less than the current size, the string is truncated. If n is larger, the memory is reallocated to exactly this amount, and the additional characters are c characters.
