lower_bound_search(+Map, ++SearchKey, ?Key, ?Value)
Search a map for the smallest key no smaller than SearchKey.
- A map
- A key to search for
- The key found
- The value corresponding to Key
This predicate searches the map Map for the entry with the
smallest key which is no smaller than SearchKey. If such a key is
found, then it attempts to unify it with Key and the corresponding
value with Value.
This predicate should only be called with maps created by other
predicates from the map module.
Fails if there are no keys at least as large as SearchKey in Map or if Key and Value do not unify with the key and value found.
