final class AgletOutputStream

extends java.io.ObjectOutputStream

An instance of this class writes objects and class data into an output stream. This aglet output stream writes objects, class data of these objects and class data of all super classes of these classes. Data written into the output stream must be read by an instance of the AgletInputStream. This aglet output stream writes the name of the class, the URL of its origin , length of class data and class data. If the class is common whose package is "java", "atp" or "aglets", the class data will not be written.
