Category: containers | Component type: concept |
X | A type that is a model of Multiple Associative Container |
a | Object of type X |
t | Object of type X::value_type |
k | Object of type X::key_type |
p, q | Object of type X::iterator |
Name | Expression | Type requirements | Return type |

Range constructor |
X(i, j) X a(i, j); |
i and j are Input Iterators whose value type is convertible to T [1] | |
Insert element | a.insert(t) | X::iterator | |
Insert range | a.insert(i, j) | i and j are Input Iterators whose value type is convertible to X::value_type. | void |

[i,j) is a valid range. | Creates an associative container that contains all elements in the range [i,j). | size() is equal to the distance from i to j. Each element in [i, j) is present in the container. |
Insert element | a.insert(t) | Inserts t into a. | The size of a is incremented by 1. The value of a.count(t) is incremented by 1. | |
Insert range | a.insert(i, j) | [i, j) is a valid range. | Equivalent to a.insert(t) for each object t that is pointed to by an iterator in the range [i, j). Each element is inserted into a. | The size of a is incremented by j - i. |
Average complexity for insert range is at most O(N * log(size() + N)), where N is j - i.
[1] At present (early 1998), not all compilers support "member templates". If your compiler supports member templates then i and j may be of any type that conforms to the Input Iterator requirements. If your compiler does not yet support member templates, however, then i and j must be of type const T* or of type X::const_iterator.
