std::flat_map
| class value_compare; |
(since C++23) | |
std::flat_map::value_compare is a function object that compares objects of type std::flat_map::const_reference (a pair of references to the stored key/value) by comparing the first components (i.e. keys) of the passed pairs.

std::flat_map<Key,T,Compare,KeyContainer,MappedContainer>::value_compare::value_compare
| private: value_compare( key_compare c ); |
(exposition only*) | |
Initializes the underlying instance of the comparator comp to c.
Parameters
| c | - | a comparator to assign |
std::flat_map<Key,T,Compare,KeyContainer,MappedContainer>::value_compare::operator()
| bool operator()( const const_reference& lhs, const const_reference& rhs ) const; |
|
Compares lhs.first and rhs.first by calling the stored comparator comp.
Parameters
| lhs, rhs | - | values to compare |
Return value
comp(lhs.first, rhs.first)
[edit] Exceptions
May throw implementation-defined exceptions.
