Method Detail

serialize

void serialize(T t,
               DataOutput out)
        throws IOException

Throws:

IOException

sizeHint

int sizeHint()

Returns 0 to indicate unknown (unbounded) capacity. Otherwise returns a value that will be used to size internal byte arrays to receive the serialized bytes ready for deserialization. An appropriate sizeHint will reduce array copying (like in `ByteArrayOutputStream`) to improve performance.

Returns:

size hint to avoid byte array copying.
