All Methods Instance Methods Abstract Methods Concrete Methods
Modifier and Type	Method	Description
`protected abstract int`	`byteAt(BytesRef ref, int i)`	Return the unsigned byte to use for comparison at index `i`, or `-1` if all bytes that are useful for comparisons are exhausted.
`int`	`compare(BytesRef o1, BytesRef o2)`
`int`	`compare(BytesRef o1, BytesRef o2, int k)`	Compare two bytes refs that first k bytes are already guaranteed to be equal.

  - byteAt
```
protected abstract int byteAt(BytesRef ref,
                              int i)
```
    Return the unsigned byte to use for comparison at index i, or -1 if all bytes that are useful for comparisons are exhausted. This may only be called with a value of i between 0 included and comparedBytesCount excluded.
  - compare
```
public final int compare(BytesRef o1,
                         BytesRef o2)
```
    Specified by:
    
    compare in interface Comparator<BytesRef>
  - compare
```
public int compare(BytesRef o1,
                   BytesRef o2,
                   int k)
```
    Compare two bytes refs that first k bytes are already guaranteed to be equal.
