Constructor Detail

FastBytesWritable

public FastBytesWritable()

FastBytesWritable

public FastBytesWritable(byte[] bytes,
                         int size)

Create a BytesWritable using the byte array as the initial value.

Parameters:

bytes - This array becomes the backing storage for the object.

Method Detail

getLength

public int getLength()

Get the current size of the buffer.

Specified by:

getLength in class BinaryComparable

set

getBytes

public byte[] getBytes()

Get the data from the BytesWritable.

Specified by:

getBytes in class BinaryComparable

Returns:

The data is only valid between 0 and getLength() - 1.
