Class Method Details

.string_of_length(length, base_string = BASE_STRING) ⇒ String

Return a string of the given length, built by trimming or extending the given base_string.

Parameters:

  • length (Integer) —

    the length of the string to be returned.

  • base_string (String) (defaults to: BASE_STRING) —

    the base string to be trimmed or extended.

Returns:

  • (String) —

    a string of the given length.

Raises:

  • (TypeError) —

    if length is not an Integer.

  • (TypeError) —

    if base_string is not a String.

  • (RangeError) —

    if length is negative.

end

.strings_in_length_range(range, base_string = BASE_STRING) ⇒ Hash

Return a hash of strings of minimum and maximum length for the given range.

Parameters:

  • range (Range) —

    specifies the minimum and maximum string lengths.

  • base_string (String) (defaults to: BASE_STRING) —

    specifies the base_string

Returns:

  • (Hash) —
