The annotated element size must be between the specified boundaries (included).

Supported types are:

  • CharSequence (length of character sequence is evaluated)
  • Collection (collection size is evaluated)
  • Map (map size is evaluated)
  • Array (array length is evaluated)

null elements are considered valid.
