Examples of java.io.Externalizable.writeExternal()

java.io.Externalizable.writeExternal()
The object implements the writeExternal method to save its contents by calling the methods of DataOutput for its primitive values or calling the writeObject method of ObjectOutput for objects, strings, and arrays. @serialData Overriding methods should use this tag to describethe data layout of this Externalizable object. List the sequence of element types and, if possible, relate the element to a public/protected field and/or method of this Externalizable class. @param out the stream to write the object to @exception IOException Includes any I/O exceptions that may occur
