H
must provide a const
function that takes a single argument convertible to type T
and returns a value of type size_t
.
Equivalent elements within the collection are grouped together based on an equality object of type EQ
. EQ
must ensure this grouping via a function that takes two arguments convertible to type T
and returns a value of type bool
.
The value
type must have operator==()
defined. This requirement is imposed by the C++ Standard Library.
Class RWTValHashSet offers the same interface to a collection that does not accept multiple items that compare equal to each other.
Class rw_hashmultiset<T,H,EQ,A> is the C++ Standard Library collection class that serves as the underlying implementation for RWTValHashMultiSet.

Destructively performs a set-theoretic union operation on self and rhs. Self is replaced by the result. Note the uppercase 'U'
in Union
to avoid conflict with the C++ reserved word.
