References __gnu_debug::_Safe_sequence_base::_M_version.

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.

  __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 897 of file basic_string.h.

reference std::basic_string< _CharT, _Traits, _Allocator >::back | ( |  | ) |

inlineinherited

Returns a read/write reference to the data at the last element of the string.

Definition at line 930 of file basic_string.h.

const_reference std::basic_string< _CharT, _Traits, _Allocator >::back | ( |  | ) | const

inlinenoexceptinherited

Returns a read-only (constant) reference to the data at the last element of the string.

Definition at line 938 of file basic_string.h.

size_type std::basic_string< _CharT, _Traits, _Allocator >::capacity | ( |  | ) | const

inlinenoexceptinherited

Returns the total number of characters that the string can hold before needing to allocate more memory.

Definition at line 785 of file basic_string.h.

int std::basic_string< _CharT, _Traits, _Allocator >::compare | ( | const basic_string< _CharT, _Traits, _Allocator > & | __str | ) | const

inlineinherited

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 2244 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.

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
| ) |  | 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.

bool std::basic_string< _CharT, _Traits, _Allocator >::empty | ( |  | ) | const

inlinenoexceptinherited

Returns true if the string is empty. Equivalent to `*this == ""`.

Definition at line 821 of file basic_string.h.

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.
