public void writeObject(DataBuffer<byte[]> buffer, String value, long index)
DataLayoutIt is the responsibility of the implementors of this interface to write the converted value
to the given buffer before this call returns, using the most appropriate method. For example,
for a layout converting a BigInteger to a single long,
@Override
public void writeObject(LongDataBuffer buffer, BigInteger value, long index) {
buffer.setLong(value.longValue(), index);
}
If a single user value scales over more than one buffer values, index indicates the
starting position of the sequence to be written to the buffer.writeObject in interface DataLayout<DataBuffer<byte[]>,String>buffer - the buffer to write tovalue - the value in the user type to convert and writeindex - index in the buffer where the converted value should be writtenpublic String readObject(DataBuffer<byte[]> buffer, long index)
DataLayoutn = scale() values from the buffer at the given index and return them as a single
value in the user type.
It is the responsibility of the implementors of this interface to read the value to be
converted from the given buffer, using the most appropriate method. For example, for a layout
that converting a single long to a BigInteger,
@Override
public BigInteger readObject(LongDataBuffer buffer, long index) {
return BigInteger.valueOf(buffer.getLong(index));
}
If a single user value scales over more than one buffer values, index indicates the
