Remarks
The constructor:
hash_multiset();
initializes the controlled sequence with no elements, with the default ordering predicate key_compare(), and with the default hash function. You use it to specify an empty initial controlled sequence, with the default ordering predicate and hash function.
The constructor:
explicit hash_multiset(key_compare^ pred);
initializes the controlled sequence with no elements, with the ordering predicate pred, and with the default hash function. You use it to specify an empty initial controlled sequence, with the specified ordering predicate and the default hash function.
The constructor:
hash_multiset(key_compare^ pred, hasher^ hashfn);
initializes the controlled sequence with no elements, with the ordering predicate pred, and with the hash function hashfn. You use it to specify an empty initial controlled sequence, with the specified ordering predicate and hash function.
The constructor:
hash_multiset(hash_multiset<Key>% right);
initializes the controlled sequence with the sequence [right.hash_multiset::begin (STL/CLR)(), right.hash_multiset::end (STL/CLR)()), with the default ordering predicate, and with the default hash function. You use it to specify an initial controlled sequence that is a copy of the sequence controlled by the hash_multiset object right, with the default ordering predicate and hash function.
The constructor:
hash_multiset(hash_multiset<Key>^ right);
initializes the controlled sequence with the sequence [right->hash_multiset::begin (STL/CLR)(), right->hash_multiset::end (STL/CLR)()), with the default ordering predicate, and with the default hash function. You use it to specify an initial controlled sequence that is a copy of the sequence controlled by the hash_multiset object right, with the default ordering predicate and hash function.
The constructor:
template<typename InIter>
hash_multiset(InIter first, InIter last);
initializes the controlled sequence with the sequence [first, last), with the default ordering predicate, and with the default hash function. You use it to make the controlled sequence a copy of another sequence, with the default ordering predicate and hash function.
The constructor:
template<typename InIter>
hash_multiset(InIter first, InIter last,
key_compare^ pred);
initializes the controlled sequence with the sequence [first, last), with the ordering predicate pred, and with the default hash function. You use it to make the controlled sequence a copy of another sequence, with the specified ordering predicate and the default hash function.
The constructor:
template<typename InIter>
hash_multiset(InIter first, InIter last,
key_compare^ pred, hasher^ hashfn);
initializes the controlled sequence with the sequence [first, last), with the ordering predicate pred, and with the hash function hashfn. You use it to make the controlled sequence a copy of another sequence, with the specified ordering predicate and hash function.
The constructor:
hash_multiset(System::Collections::Generic::IEnumerable<Key>^ right);
initializes the controlled sequence with the sequence designated by the enumerator right, with the default ordering predicate, and with the default hash function. You use it to make the controlled sequence a copy of another sequence described by an enumerator, with the default ordering predicate and hash function.
The constructor:
hash_multiset(System::Collections::Generic::IEnumerable<Key>^ right,
key_compare^ pred);
initializes the controlled sequence with the sequence designated by the enumerator right, with the ordering predicate pred, and with the default hash function. You use it to make the controlled sequence a copy of another sequence described by an enumerator, with the specified ordering predicate and default hash function.
The constructor:
hash_multiset(System::Collections::Generic::IEnumerable<Key>^ right,
key_compare^ pred, hasher^ hashfn);
initializes the controlled sequence with the sequence designated by the enumerator right, with the ordering predicate pred, and with the hash function hashfn. You use it to make the controlled sequence a copy of another sequence described by an enumerator, with the specified ordering predicate and hash function.
