  - byteArray
```
public static void byteArray(StringBuilder buffer,
                             byte[] bytes)
```
  - longHex
```
public static String longHex(long x)
```
    Unlike Long.toHexString(long) returns a String with a "0x" prefix and all the leading zeros.
  - bytesRefToString
```
public static String bytesRefToString(BytesRef b)
```
    Builds a String with both textual representation of the BytesRef data and the bytes hex values. For example: "hello [68 65 6c 6c 6f]". If the content is not a valid UTF-8 sequence, only the bytes hex values are returned, as per BytesRef.toString().
