- - This method determines how many characters will be needed to represent an integer delta value when encoded - - using the polyline encoding algorithm. It performs the same zigzag encoding transformation as - - but only calculates the required buffer size without actually writing any data. - -

- -

- - The calculation process: - - -

  1. Applies zigzag encoding: left-shifts the value by 1 bit, then inverts all bits if the original value was negative
  2. Counts how many 5-bit chunks are needed to represent the encoded value
  3. Each chunk requires one character, with a minimum of 1 character for any value
- -

- -

- - This method is useful for pre-allocating buffers of the correct size before encoding polyline data, helping to avoid - - buffer overflow checks during the actual encoding process. - -

- -

- - The method uses a long internally to prevent overflow during the left-shift operation on large negative values. - -

- - The precision determines the number of decimal places to which each coordinate value (latitude or longitude) - - is multiplied and truncated (not rounded) before encoding.
