Range constructor |
X(i, j) X a(i, j); |
[i,j) is a valid range. | Creates an associative container that contains all of the elements in the range [i,j) that have unique keys, using hasher() as the hash function and key_equal() as the key equality function. | size() is less than or equal to the distance from i to j. The bucket count is an unspecified default value. The hash function is hasher(), and the key equality function is key_equal(). |
Range constructor with bucket count |
X(i, j, n) X a(i, j, n); |
[i,j) is a valid range. | Creates an associative container that contains all of the elements in the range [i,j) that have unique keys, using at least n buckets, and using hasher() as the hash function and key_equal() as the key equality function. | size() is less than or equal to the distance from i to j. The bucket count is greater than or equal to n. The hash function is hasher(), and the key equality function is key_equal(). |
Range constructor with hash function |
X(i, j, n, h) X a(i, j, n, h); |
[i,j) is a valid range. | Creates an associative container that contains all of the elements in the range [i,j) that have unique keys, using at least n buckets, and using h as the hash function and key_equal() as the key equality function. | size() is less than or equal to the distance from i to j. The bucket count is greater than or equal to n. The hash function is h, and the key equality function is key_equal(). |
Range constructor with key equal |
X(i, j, n, h, k) X a(i, j, n, h, k); |
[i,j) is a valid range. | Creates an associative container that contains all of the elements in the range [i,j) that have unique keys, using at least n buckets, and using h as the hash function and k as the key equality function. | size() is less than or equal to the distance from i to j. The bucket count is greater than or equal to n. The hash function is h, and the key equality function is k. |
[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.
