Attempt to preallocate enough memory for specified number of characters.

Parameters:
res_argNumber of characters required.
Exceptions:
std::length_errorIf res_arg exceeds max_size().

This function attempts to reserve enough memory for the string to hold the specified number of characters. If the number requested is more than max_size(), length_error is thrown.

The advantage of this function is that if optimal code is a necessity and the user can determine the string length that will be required, the user can reserve the memory in advance, and thus prevent a possible reallocation of memory and copying of string data.

cCharacter to fill any new elements.

This function will resize the string to the specified number of characters. If the number is smaller than the string's current size the string is truncated, otherwise the string is extended and new elements are set to c.

void __gnu_debug::basic_string::resize ( size_type  __n) [inline]

Resizes the string to the specified number of characters.

Parameters:
nNumber of characters the string should contain.

This function will resize the string to the specified length. If the new size is smaller than the string's current size the string is truncated, otherwise the string is extended and new characters are default-constructed. For basic types such as char, this means setting them to 0.

Reimplemented from std::basic_string< _CharT, _Traits, _Allocator >.

size_type __gnu_debug::basic_string::rfind ( const _CharT *  __s,
size_type  __pos,
size_type  __n 
) const [inline]

Find last position of a C substring.

Parameters:
sC string to locate.
posIndex of character to search back from.
nNumber of characters from s to search for.
Returns:
Index of start of last occurrence.

Starting from pos, searches backward for the first n characters in s within this string. If found, returns the index where it begins. If not found, returns npos.

size_type __gnu_debug::basic_string::rfind ( const _CharT *  __s,
size_type  __pos = _Base::npos 
) const [inline]

Find last position of a C string.

Parameters:
sC string to locate.
posIndex of character to start search at (default end).
Returns:
Index of start of last occurrence.

Starting from pos, searches backward for the value of s within this string. If found, returns the index where it begins. If not found, returns npos.

size_type __gnu_debug::basic_string::rfind ( _CharT  __c,
size_type  __pos = _Base::npos 
) const [inline]

Find last position of a character.

Parameters:
cCharacter to locate.
posIndex of character to search back from (default end).
Returns:
Index of last occurrence.

Starting from pos, searches backward for c within this string. If found, returns the index where it was found. If not found, returns npos.

size_type std::basic_string::rfind ( const basic_string< _CharT, _Traits, _Allocator > &  __str,
size_type  __pos = npos 
) const [inline, inherited]

Find last position of a string.

Parameters:
strString to locate.
posIndex of character to search back from (default end).
Returns:
Index of start of last occurrence.

Starting from pos, searches backward for value of str within this string. If found, returns the index where it begins. If not found, returns npos.

size_type std::basic_string::size ( ) const [inline, inherited]

Returns the number of characters in the string, not including any null-termination.

basic_string __gnu_debug::basic_string::substr ( size_type  __pos = 0,
size_type  __n = _Base::npos 
) const [inline]

Get a substring.

Parameters:
posIndex of first character (default 0).
nNumber of characters in substring (default remainder).
Returns:
The new string.
Exceptions:
std::out_of_rangeIf pos > size().

Construct and return a new string using the n characters starting at pos. If the string is too short, use the remainder of the characters. If pos is beyond the end of the string, out_of_range is thrown.

Parameters:

Exchanges the contents of this string with that of s in constant time.
