concurrent_unordered_set::insert Method
Adds elements to the concurrent_unordered_set object.
std::pair<iterator, bool> insert(
const value_type& _Value
);
iterator insert(
const_iterator _Where,
const value_type& _Value
);
template<
class _Iterator
>
void insert(
_Iterator_First,
_Iterator_Last
);
template<
class _Valty
>
std::pair<iterator, bool> insert(
_Valty&& _Value
);
template<
class _Valty

typename std::tr1::enable_if<!std::tr1::is_same<const_iterator, typename std::tr1::remove_reference<_Valty>::type>::value, iterator>::type insert(
const_iterator _Where,
_Valty&& _Value
);
Parameters
_Iterator
The iterator type used for insertion._Valty
The type of the value inserted into the set._Value
The value to be inserted._Where
The starting location to search for an insertion point._First
The beginning of the range to insert._Last
The end of the range to insert.
Return Value
A pair that contains an iterator and a boolean value. See the Remarks section for more details.
Remarks
The first member function determines whether an element X exists in the sequence whose key has equivalent ordering to that of _Value. If not, it creates such an element X and initializes it with _Value. The function then determines the iterator where that designates X. If an insertion occurred, the function returns std::pair(where, true). Otherwise, it returns std::pair(where, false).
The second member function returns insert(_Value), using _Where as a starting place within the controlled sequence to search for the insertion point.
The third member function inserts the sequence of element values from the range [_First, _Last).
The last two member functions behave the same as the first two, except that _Value is used to construct the inserted value.
