ByteArrayComparable
public ByteArrayComparable(byte[] value)
- Constructor.
- Parameters:
value - the value to compare against
getValue
public byte[] getValue()
toByteArray
public abstract byte[] toByteArray()
- Returns:
- The comparator serialized using pb
parseFrom
public static ByteArrayComparable parseFrom(byte[] pbBytes)
throws DeserializationException
- Parameters:
pbBytes - A pb serialized ByteArrayComparable instance
- Returns:
- An instance of
ByteArrayComparable made from bytes
- Throws:
DeserializationException- See Also:
toByteArray()
compareTo
public int compareTo(byte[] value)
- Specified by:
compareTo in interface Comparable<byte[]>
compareTo
public abstract int compareTo(byte[] value,
int offset,
int length)
- Special compareTo method for subclasses, to avoid
copying byte[] unnecessarily.
- 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.
