basic_static_string::compare (9 of 9 overloads)

Compare a string with the string.

Synopsis

template<
    [role red error.param neither has a declname nor a 'class ' prefix in the type][role red error.param neither has a declname nor a 'class ' prefix in the type][role red error.param neither has a declname nor a 'class ' prefix in the type][role red error.param neither has a declname nor a 'class ' prefix in the type]>
constexpr int
compare(
    size_type pos1,
    size_type count1,
    const T& t,
    size_type pos2,
    size_type count2 = npos) const;

Let sub1 be substr(pos1, count1), sub2 be string_view_type(t).substr(pos2, count2), and comp be traits_type::compare(sub1.data(), sub2.data(), std::min(sub1.size(), sub2.size()). If comp != 0, then the result is comp. Otherwise, the result is 0 if sub1.size() == sub2.size(), -1 if sub1.size() < sub2.size(), and 1 otherwise.

Complexity

Linear.

Exception Safety

Strong guarantee.

Template Parameters

Type	Description
`T`	The type of the object to convert.

Constraints

std::is_convertible<const T&, string_view>::value &&
!std::is_convertible<const T&, const_pointer>::value.

Return Value

The result of lexicographically comparing sub1 and sub2.

Parameters

Name	Description
`pos1`	The index at which to begin the substring in the string.
`count1`	The length of the substring in the string.
`t`	The string to compare.
`pos2`	The index at which to begin the substring in the string view.
`count2`	The length of the substring in the string view.
