NAME¶

std::flat_multiset::lower_bound - std::flat_multiset::lower_bound

Synopsis¶

iterator lower_bound( const Key& key ); (1) (since C++23)
const_iterator lower_bound( const Key& key ) const; (2) (since C++23)
template< class K > (3) (since C++23)
iterator lower_bound( const K& x );
template< class K > (4) (since C++23)
const_iterator lower_bound( const K& x ) const;

1,2) Returns an iterator pointing to the first element that is not less than (i.e.
greater or equal to) key.
3,4) Returns an iterator pointing to the first element that compares not less (i.e.
greater or equal) to the value x. This overload participates in overload resolution
only if the qualified-id Compare::is_transparent is valid and denotes a type. It
allows calling this function without constructing an instance of Key.

Parameters¶

key - key value to compare the elements to
x - alternative value that can be compared to Key

Return value¶

Iterator pointing to the first element that is not less than key. If no such element
is found, a past-the-end iterator (see end()) is returned.

Complexity¶

Logarithmic in the size of the container.
