Foil 32 Serialization - I

From Javabeans Basic Information Track Computational Science Course CPS616 -- Spring Semester 1999. by Geoffrey Fox, Nancy McCracken, Wojtek Furmanski


The Serialization interface is essentially a flag as there are NO methods or data attached to this interface -- implementing Serialization implies your willingness to be saved using default Java mechanism!
The Serialization process is typically implemented by a container (Java Applet, Application, Java Beans Container)
Typically one serializes to an output stream and deserializes from an input stream
DataOutput Interface describes streams that can write out data in a machine independent fashion
ObjectOutputStream class extends DataOutput (and an ObjectOutput Interface) and defines methods to write out variables of all the primitive types with a general
  • writeObject(Object obj)
  • and a whole bunch of methods like writeShort(int data)
