## Class ProtobufUtil

- java.lang.Object
- - com.fasterxml.jackson.dataformat.protobuf.ProtobufUtil

-     public class ProtobufUtil
      extends Object

- - ### Field Summary

    Fields
    Modifier and Type | Field and Description
    --- | ---
    `static int` | `SECONDARY_BUFFER_LENGTH`
    `static int[]` | `sUtf8UnitLengths`

  - ### Constructor Summary

    Constructor and Description
    `ProtobufUtil()`

  - ### Method Summary

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `static byte[]` | `allocSecondary(byte[] curr)` While we could get all fancy on allocating secondary buffer (after initial one), let's start with very simple strategy of medium-length buffer.
    `static int` | `appendLengthLength(int len, byte[] buffer, int ptr)` NOTE: caller MUST ensure buffer has room for at least 5 bytes
    `static byte[]` | `lengthAsBytes(int len)`
    `static int` | `lengthLength(int len)`
    `static int` | `zigzagDecode(int encoded)`
    `static long` | `zigzagDecode(long encoded)`
    `static int` | `zigzagEncode(int input)`
    `static long` | `zigzagEncode(long input)`
