writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Throws:

IOException

writeTo

public void writeTo(DataOutput out)
             throws IOException

The object implements the writeTo method to save its contents by calling the methods of DataOutput for its primitive values and strings or calling the writeTo method for other objects.

Parameters:

out - the stream to write the object to.

Throws:

IOException

ClassNotFoundException

readFrom

public void readFrom(DataInput in)
              throws IOException

The object implements the readFrom method to restore its contents by calling the methods of DataInput for primitive types and strings or calling readExternal for other objects. The readFrom method must read the values in the same sequence and with the same types as were written by writeTo.
