writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Writes this object to data output. Note that this is not externalizable interface because we want to eliminate any marshaller.

Specified by:

writeExternal in interface Externalizable

Parameters:

out - Data output to write.

Throws:

IOException - If write failed.

readExternal

public void readExternal(ObjectInput in)
                  throws IOException

Reads object from data input. Note we do not use externalizable interface to eliminate marshaller.

Specified by:

readExternal in interface Externalizable

Parameters:

in - Data input.

Throws:

IOException - If read failed.
