public interface PortableObject

The PortableObject interface is implemented by Java classes that can self- serialize and deserialize their state to and from a POF data stream.

The readExternal(com.tangosol.io.pof.PofReader) and writeExternal(com.tangosol.io.pof.PofWriter) methods of the PortableObject interface are implemented by a class to give the class complete control its own POF serialization and deserialization.

Method Summary

void	readExternal(PofReader in) Restore the contents of a user type instance by reading its state using the specified PofReader object.
void	writeExternal(PofWriter out) Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Method Detail

readExternal

void readExternal(PofReader in)
                  throws java.io.IOException

Restore the contents of a user type instance by reading its state using the specified PofReader object.

Parameters:

in - the PofReader from which to read the object's state

Throws:

java.io.IOException - if an I/O error occurs

writeExternal

void writeExternal(PofWriter out)
                   throws java.io.IOException

Save the contents of a POF user type instance by writing its state using the specified PofWriter object.

Parameters:

out - the PofWriter to which to write the object's state

Throws:

java.io.IOException - if an I/O error occurs
