Functions

resolveQuantifier()

Resolve the `quant` parameter into its AQL quantifier keyword.

resolveQuantifier(mixed $value) : string

The quant value answers the element axis of an array filter — « how many elements must satisfy the condition » — independently of the comparator (which lives in op). Three forms are accepted:

  • a named quantifier any / all / none → ANY / ALL / NONE (resolved through FilterQuantifier::getAlias());
  • a bare integer n (or its numeric string, e.g. 3 / "3") → AT LEAST (n). The threshold is cast to an int and inlined, which is injection-safe.

The returned keyword drives both array surfaces uniformly:

  • scalar arrays via the array comparison operator (doc.scores ALL >= @v);
  • object arrays via the question-mark operator (doc.reviews[? ALL FILTER …]).
Parameters
$value : mixed

The raw quant parameter (any/all/none or an integer).
