public interface DataSerializable

DataSerializable is a serialization method as an alternative to standard Java serialization. DataSerializable is very similar to Externalizable and relies on reflection to create instances using classnames.

IdentifiedDataSerializable, Portable, VersionedPortable

Method Summary

Modifier and Type	Method and Description
void	readData(ObjectDataInput in) Reads fields from the input stream
void	writeData(ObjectDataOutput out) Writes object fields to output stream

Method Detail

writeData

void writeData(ObjectDataOutput out)
        throws IOException

Writes object fields to output stream

Parameters:

out - output

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the output stream has been closed.

readData

void readData(ObjectDataInput in)
       throws IOException

Reads fields from the input stream

Parameters:

in - input

Throws:

IOException - if an I/O error occurs. In particular, an IOException may be thrown if the input stream has been closed.
