    • mapToLengths

      public static ImmutableList<java.lang.Integer> mapToLengths​(ImmutableList<java.lang.String> texts)
      Creates and returns a list whose contents are the lengths of the specified input texts. The order in the input texts must be preserved in the result. For example, if the input is ["programming", "languages", "Dan"] then the returned list should be [11, 9, 3].
      Parameters:
      texts - the specified list of texts
      Returns:
      the lengths of the specified texts

    • mapToStrictlyLessThan

      public static ImmutableList<java.lang.Boolean> mapToStrictlyLessThan​(ImmutableList<java.lang.Integer> xs, int threshold)
      Creates and returns a list whose contents are the results of whether or not the specified input items are strictly less than the specified threshold. For example, if the input list is [131, 71, 66, 99, 425, 231, 4, 12] and the threshold is 99 then the returned list should be [false, true, true, false, false, false, true, true].
      Parameters:
      xs - the input list of values
      threshold - value used to determine less than
      Returns:
      a list which holds whether or not each value is less than threshold or not
