Detach all iterators, leaving them singular.
void __gnu_debug::_Safe_sequence_base::_M_detach_singular () [protected], [inherited]
Detach all singular iterators.
Postcondition:
for all iterators i attached to this sequence, i->_M_version == _M_version.
__gnu_cxx::__mutex& __gnu_debug::_Safe_sequence_base::_M_get_mutex () [protected],
[inherited]
For use in _Safe_sequence.

void __gnu_debug::_Safe_sequence< basic_string< _CharT, _Traits, _Allocator >
>::_M_invalidate_if (_Predicate __pred) [inherited]
Invalidates all iterators x that reference this sequence, are not singular, and for which
__pred(x) returns true. __pred will be invoked with the normal iterators nested in the
safe ones.
Definition at line 38 of file safe_sequence.tcc.
void __gnu_debug::_Safe_sequence_base::_M_revalidate_singular () [protected], [inherited]
Revalidates all attached singular iterators. This method may be used to validate iterators
that were invalidated before (but for some reason, such as an exception, need to become
valid again).
void __gnu_debug::_Safe_sequence_base::_M_swap (_Safe_sequence_base & __x) [protected],
[noexcept], [inherited]
Swap this sequence with the given sequence. This operation also swaps ownership of the
iterators, so that when the operation is complete all iterators that originally referenced
one container now reference the other container.
void __gnu_debug::_Safe_sequence< basic_string< _CharT, _Traits, _Allocator >
>::_M_transfer_from_if (_Safe_sequence< basic_string< _CharT, _Traits, _Allocator > > &
__from, _Predicate __pred) [inherited]
Transfers all iterators x that reference from sequence, are not singular, and for which
__pred(x) returns true. __pred will be invoked with the normal iterators nested in the
safe ones.

__n Number of characters to use.
Returns:
Reference to this string.
Exceptions:
std::out_of_range if pos is not a valid index.
This function sets this string to the substring of __str consisting of __n characters at

Parameters:
__n The index of the character to access.
Returns:
Read-only (const) reference to the character.
Exceptions:
std::out_of_range If n is an invalid index.
This function provides for safer data access. The parameter is first checked that it is in
the range of the string. The function throws out_of_range if the check fails.
Definition at line 4002 of file basic_string.h.
reference std::basic_string< _CharT, _Traits, _Allocator >::at (size_type __n) [inline],

Parameters:
__n The index of the character to access.
Returns:
Read/write reference to the character.
Exceptions:
std::out_of_range If n is an invalid index.
This function provides for safer data access. The parameter is first checked that it is in
the range of the string. The function throws out_of_range if the check fails. Success
results in unsharing the string.
Definition at line 4024 of file basic_string.h.
reference std::basic_string< _CharT, _Traits, _Allocator >::back () [inline], [inherited]
Returns a read/write reference to the data at the last element of the string.

int std::basic_string< _CharT, _Traits, _Allocator >::compare (const basic_string< _CharT,
_Traits, _Allocator > & __str) const [inline], [inherited]
Compare to a string.
Parameters:
__str String to compare against.
Returns:
Integer < 0, 0, or > 0.
Returns an integer < 0 if this string is ordered before __str, 0 if their values are
equivalent, or > 0 if this string is ordered after __str. Determines the effective length
rlen of the strings to compare as the smallest of size() and str.size(). The function then
compares the two strings by calling traits::compare(data(), str.data(),rlen). If the
result of the comparison is nonzero returns it, otherwise the shorter one is ordered
first.
Definition at line 5684 of file basic_string.h.
int std::basic_string< _CharT, _Traits, _Allocator >::compare (size_type __pos, size_type
__n, const basic_string< _CharT, _Traits, _Allocator > & __str) const [inherited]
Compare substring to a string.
Parameters:
__pos Index of first character of substring.
__n Number of characters in substring.
__str String to compare against.
Returns:
Integer < 0, 0, or > 0.
Form the substring of this string from the __n characters starting at __pos. Returns an
integer < 0 if the substring is ordered before __str, 0 if their values are equivalent, or
> 0 if the substring is ordered after __str. Determines the effective length rlen of the
strings to compare as the smallest of the length of the substring and __str.size(). The
function then compares the two strings by calling
traits::compare(substring.data(),str.data(),rlen). If the result of the comparison is
nonzero returns it, otherwise the shorter one is ordered first.
Definition at line 1385 of file basic_string.tcc.
int std::basic_string< _CharT, _Traits, _Allocator >::compare (size_type __pos1, size_type
__n1, const basic_string< _CharT, _Traits, _Allocator > & __str, size_type __pos2,
size_type __n2 = npos) const [inherited]
Compare substring to a substring.
Parameters:
__pos1 Index of first character of substring.
__n1 Number of characters in substring.
__str String to compare against.
__pos2 Index of first character of substring of str.
__n2 Number of characters in substring of str.
Returns:
Integer < 0, 0, or > 0.
Form the substring of this string from the __n1 characters starting at __pos1. Form the
substring of __str from the __n2 characters starting at __pos2. Returns an integer < 0 if
this substring is ordered before the substring of __str, 0 if their values are equivalent,
or > 0 if this substring is ordered after the substring of __str. Determines the effective
length rlen of the strings to compare as the smallest of the lengths of the substrings.
The function then compares the two strings by calling
traits::compare(substring.data(),str.substr(pos2,n2).data(),rlen). If the result of the
comparison is nonzero returns it, otherwise the shorter one is ordered first.
Definition at line 1400 of file basic_string.tcc.

void std::basic_string< _CharT, _Traits, _Allocator >::reserve (size_type __res_arg = 0)
[inherited]
Attempt to preallocate enough memory for specified number of characters.
Parameters:
__res_arg Number of characters required.
Exceptions:
std::length_error If __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.
