bsl::basic_string<wchar_t>::find

Synopses

Declared in <bslstl_string.h>

Return the position of the first occurrence of the specified character, if such an occurrence can be found in this string (on or after the optionally specified position if such a position is specified), and return npos otherwise.

size_type
find(
    wchar_t character,
    size_type position = 0) const;

Return the starting position of the first occurrence of the specified substring, if such a substring can be found in this string (on or after the optionally specified position if such a position is specified) using CHAR_TRAITS::eq to compare characters, and return npos otherwise.

size_type
find(
    basic_string<wchar_t> const& substring,
    size_type position = 0) const noexcept;

Same as the three-argument find overload with position 0.

size_type
find(
    wchar_t const* substring,
    size_type position = 0) const;

Return the starting position of the first occurrence of the specified substring, if such a substring can be found in this string (on or after the optionally specified position if such a position is specified) using CHAR_TRAITS::eq to compare characters, and return npos otherwise. The behavior is undefined unless the conversion from STRING_VIEW_LIKE_TYPE to bsl::basic_string_view<CHAR_TYPE, CHAR_TRAITS> does not throw any exception. Note that this behavior differs from the behavior implemented in the standard container, where the following noexcept specification is used: ` noexcept( std::is_nothrow_convertible_v<const T&, std::basic_string_view<CharT, Traits> >) `

template<class STRING_VIEW_LIKE_TYPE>
size_type
find(
    STRING_VIEW_LIKE_TYPE const& substring,
    size_type position = 0) const noexcept(true);

Return the starting position of the first occurrence of the specified substring of the optionally specified numChars length, if such a substring can be found in this string (on or after the optionally specified position if such a position is specified) using CHAR_TRAITS::eq to compare characters, and return npos otherwise. If numChars is not specified, CHAR_TRAITS::length(substring) is used.

    size_type numChars) const;
