      public static String toString(Map map)

    • filterMapKey

      public static <V, R extends Map<String, V>> R filterMapKey(R map, String... regex)
      Filter Map keys through regular expression(s). Given a certain key, if String.matches(String) returns true for at least one of the given regular expressions, that key will be retained. In the event that there are no regular expressions to match, the map will retain all of its keys.
      Parameters:
      map - the map to filter
      regex - the regular expression(s) to match the keys to
      Returns:
      the filtered map

    • filterMapKeyStartWithIgnoreCase

      public static <V, R extends Map<String, V>> R filterMapKeyStartWithIgnoreCase(R map, String... searchStrings)
      Filter map keys such that each key starts with at least one of the items in the searchStrings array.
      Parameters:
      map - the map to filter
      searchStrings - the must-have prefixes of the keys
      Returns:
      the filtered map

    • mapWithKeysAndValue

    • mapWithKeysAndValueList

      public static <K, V> Map<K,List<V>> mapWithKeysAndValueList(Object... objects)
