    Description copied from class: ByteArrayComparable
    
    Special compareTo method for subclasses, to avoid copying byte[] unnecessarily.
    
    Specified by:
    
    compareTo in class ByteArrayComparable
    
    Parameters:
    value - byte[] to compare
    offset - offset into value
    length - number of bytes to compare
    
    Returns:
    a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
  - toByteArray
```
public byte[] toByteArray()
```
    Specified by:
    
    toByteArray in class ByteArrayComparable
    
    Returns:
    The comparator serialized using pb
  - parseFrom
```
public static LongComparator parseFrom(byte[] pbBytes)
                                throws DeserializationException
```
    Parameters:
    pbBytes - A pb serialized LongComparator instance
    
    Returns:
    An instance of LongComparator made from bytes
    
    Throws:
    
    DeserializationException
    See Also:
    toByteArray()
  - areSerializedFieldsEqual
```
boolean areSerializedFieldsEqual(LongComparator other)
```
    Parameters:
    other -
    
    Returns:
    true if and only if the fields of the comparator that are serialized are equal to the corresponding fields in other. Used for testing.
