BinaryComparator
public BinaryComparator(byte[] value)
- Constructor
- Parameters:
value
- value
compareTo
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 compareoffset
- offset into valuelength
- 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 BinaryComparator parseFrom(byte[] pbBytes)
throws org.apache.hadoop.hbase.exceptions.DeserializationException
- Parameters:
pbBytes
- A pb serialized BinaryComparator
instance
- Returns:
- An instance of
BinaryComparator
made from bytes
- Throws:
org.apache.hadoop.hbase.exceptions.DeserializationException
