Method Detail

getFutureData

public byte[] getFutureData()

Description copied from interface: Evolvable

Return the data read (unparsed) from a node that has a newer version of this class.

Specified by:

getFutureData in interface Evolvable

writeData

public final void writeData(DataOutput out)
                     throws IOException

Specified by:

writeData in interface DataSerializable

Throws:

IOException

readData

public final void readData(DataInput in)
                    throws IOException

Specified by:

readData in interface DataSerializable

Throws:

IOException

writeKnownData

public abstract void writeKnownData(DataOutput out)
                             throws IOException

Serializes all data the version of this class at hand knows about. AbstractEvolvableDataSerializable takes care of putting potential unknown data (it deserialized) back on the wire so that it does not get lost.

Throws:

IOException

readKnownData

public abstract void readKnownData(DataInput in)
                            throws IOException

Deserializes all data the version of this class at hand knows about. AbstractEvolvableDataSerializable takes care of receiving and storing potential unknown data from the wire in case a version newer than the one at hand was received.

Throws:

IOException
