NAME¶

std::experimental::basic_string_view::find_last_of - std::experimental::basic_string_view::find_last_of

Synopsis¶

constexpr size_type find_last_of(basic_string_view v, (1) (library fundamentals
size_type pos = npos) const noexcept; TS)
constexpr size_type find_last_of(CharT c, size_type pos = (2) (library fundamentals
npos) const noexcept; TS)
constexpr size_type find_last_of(const CharT* s, size_type (3) (library fundamentals
pos, size_type count) const; TS)
constexpr size_type find_last_of(const CharT* s, size_type (4) (library fundamentals
pos = npos) const; TS)

Finds the last character equal to any of the characters in the given character
sequence.

1) Finds the last occurence of any of the characters of v in this view, starting at
position pos.
2) Equivalent to find_last_of(basic_string_view(&c, 1), pos).
3) Equivalent to find_last_of(basic_string_view(s, count), pos).
4) Equivalent to find_last_of(basic_string_view(s), pos).

Parameters¶

v - view to search for
pos - position at which to start the search
count - length of the string of characters to search for
s - pointer to a string of characters to search for
ch - character to search for

Return value¶

Position of the last occurrence of any character of the substring, or npos if no
such character is found.

Complexity¶

O(size() * v.size()) at worst.
