hash_set::value_comp
value_compare value_comp() const;
The member function returns a function object that determines the order of elements in the
controlled sequence.
hash_set::value_compare
typedef Tr value_compare;
The type describes a function object that can compare two elements as sort keys to determine
their relative order in the controlled sequence.
hash_set::value_type
typedef Key value_type;
The type describes an element of the controlled sequence.
swap
template<class Key, class Tr, class Alloc>
void swap(
hash_multiset <Key, Tr, Alloc>& left,
hash_multiset <Key, Tr, Alloc>& right);
template<class Key, class Tr, class Alloc>
void swap(
hash_set <Key, Tr, Alloc>& left,
hash_set <Key, Tr, Alloc>& right);
The template function executes left.swap(right).
operator!=
template<class Key, class Tr, class Alloc>
bool operator!=(
const hash_set <Key, Tr, Alloc>& left,
const hash_set <Key, Tr, Alloc>& right);
template<class Key, class Tr, class Alloc>
bool operator!=(
const hash_multiset <Key, Tr, Alloc>& left,
const hash_multiset <Key, Tr, Alloc>& right);
The template function returns !(left == right).
