Detailed Description

template<typename T, typename TAlloc>
class dcpp::nub::basic_string< T, TAlloc >

Very simple string class with some useful features.

basic_string<dcpp::char_kt> and basic_string<wchar_t> both accept Unicode AND ASCII/Latin-1, so you can assign Unicode to basic_string<dcpp::char_kt> and ASCII/Latin-1 to basic_string<wchar_t> (and the other way round) if you want to.

However, note that the conversation between both is not done using any encoding. This means that dcpp::char_kt strings are treated as ASCII/Latin-1, not UTF-8, and are simply expanded to the equivalent wchar_t, while Unicode/wchar_t characters are truncated to 8-bit ASCII/Latin-1 characters, discarding all other information in the wchar_t.

Helper functions for converting between UTF-8 and wchar_t are provided outside the string class for explicit use.

other	other String to append to this string.
length	How much characters of the other string to add to this one.

other	Char string to append.
length	The length of the string to append.

other	Other string to compare.
sourcePos	where to start to compare in the string

other	Other string to compare.
n	Number of characters to compare

c	List of characters to find. For example if the method should find the first occurrence of 'a' or 'b', this parameter should be "ab".
count	Amount of characters in the list. Usually, this should be strlen(c)

c	List of characters not to find. For example if the method should find the first occurrence of a character not 'a' or 'b', this parameter should be "ab".
count	Amount of characters in the list. Usually, this should be strlen(c)

c	Character to search for.
start	start to search reverse ( default = -1, on end )

c	List of strings to find. For example if the method should find the last occurrence of 'a' or 'b', this parameter should be "ab".
count	Amount of characters in the list. Usually, this should be strlen(c)

c	Character to search for.
startPos	Position in string to start searching.

toReplace	The string to replace.
replaceWith	The string replacing the old one.

toReplace	Character to replace.
replaceWith	Character replacing the old one.

ret	The result container. Tokens are added, the container is not cleared.
delimiter	C-style string of delimiter characters
countDelimiters	Number of delimiter characters
ignoreEmptyTokens	Flag to avoid empty substrings in the result container. If two delimiters occur without a character in between or an empty substring would be placed in the result. Or if a delimiter is the last character an empty substring would be added at the end. If this flag is set, only non-empty strings are stored.
keepSeparators	Flag which allows to add the separator to the result string. If this flag is true, the concatenation of the substrings results in the original string. Otherwise, only the characters between the delimiters are returned.

begin	Start of substring.
length	Length of substring.
make_lower	copy only lower case
