All Implemented Interfaces:

Comparable<byte[]>
```
@InterfaceAudience.Public
@InterfaceStability.Stable
public class BinaryPrefixComparator
extends ByteArrayComparable
```
A comparator which compares against a specified byte array, but only compares up to the length of this byte array. For the rest it is similar to BinaryComparator.

```
public int compareTo(byte[] value,
            int offset,
            int length)
```
    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 BinaryPrefixComparator parseFrom(byte[] pbBytes)
                                        throws org.apache.hadoop.hbase.exceptions.DeserializationException
```
    Parameters:
    pbBytes - A pb serialized BinaryPrefixComparator instance
    
    Returns:
    An instance of BinaryPrefixComparator made from bytes
    
    Throws:
    
    org.apache.hadoop.hbase.exceptions.DeserializationException
