:relfileprefix: ../../../
:mrdocs:

Load into the specified `first` and `last` pointers the respective addresses of the first and last link (in the list of elements owned by this hash table) where the contained elements have a key that compares equal to the specified `key` using the `comparator` of this hash‐table, and null pointer values if there are no elements matching `key`. Note that the output values will form a closed range, where both `first` and `last` point to links satisfying the predicate (rather than a semi‐open range where `last` would point to the element following the range). Also note that this hash‐table ensures all elements having the same key form a contiguous sequence.
