std::flat_multimap<Key,T,Compare,KeyContainer,MappedContainer>::value_compare
|
(since {std}) |
std::flat_multimap::value_compare is a function object that compares objects of type std::flat_multimap::const_reference (a pair of references to the stored key/value) by comparing the first components (i.e. keys) of the passed pairs.
Member objects
| Member name | Definition |
|---|---|
comp (private) |
the comparison function object of type std::flat_multimap::key_compare(exposition-only member object*) |
Member functions
|
(constructor)
(private)
|
constructs value_compare object (public member function) |
|
operator()
|
compares two values of type value_type (public member function) |
std::flat_multimap<Key,T,Compare,KeyContainer,MappedContainer>::value_compare::value_compare
|
(exposition only*) |
Initializes the underlying instance of the comparator comp to c.
Parameters
| c | - | a comparator to assign |
std::flat_multimap<Key,T,Compare,KeyContainer,MappedContainer>::value_compare::operator()
|
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)
Exceptions
May throw implementation-defined exceptions.
