hashCode in class Object

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 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.

compareTo

public int compareTo(ByteBuffer value,
                     int offset,
                     int length)

Description copied from class: ByteArrayComparable

Special compareTo method for subclasses, to avoid copying bytes unnecessarily.

Overrides:

compareTo in class ByteArrayComparable

Parameters:

value - bytes to compare within a ByteBuffer

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 BigDecimalComparator parseFrom(byte[] pbBytes)
                                      throws org.apache.hadoop.hbase.exceptions.DeserializationException

Parameters:

pbBytes - A pb serialized BigDecimalComparator instance

Returns:

An instance of BigDecimalComparator made from bytes

Throws:

org.apache.hadoop.hbase.exceptions.DeserializationException - A deserialization exception
