An element matcher that matches a given iterable collection to a list of matchers on a per-element basis. For a successful match, any element of the matched iterable collection must be successfully matched by a next matcher of the supplied list of element matchers. For this to be possible, the matched iterable collection and the supplied list of element matchers contain the same number of elements.
Type parameters:
  • <T> – The type of the matched entity.
