sortedUnique(mixed $anyArray) : string

This helper wraps the ArangoDB AQL function SORTED_UNIQUE(anyArray) which returns a new array with all elements sorted in ascending order and duplicates removed. The original array is not modified.

Example AQL usage:

SORTED_UNIQUE([8, 4, 2, 10, 6, 2, 8, 6, 4])    // returns [2, 4, 6, 8, 10]
SORTED_UNIQUE(["c", "a", "b", "a", "c"])        // returns ["a", "b", "c"]
SORTED_UNIQUE(doc.tags)                         // sorts and deduplicates tags
Parameters
$anyArray : mixed

Array expression to sort and deduplicate.
