public class ObjectInputStream

extends java.io.ObjectInputStream

This class implements a specialization of java.io.ObjectInputStream. The features added by this specialization support user-controlled resolution of classes.

Field Summary

protected java.util.Hashtable

classRegistrations The table of className/class pair registrations to be used during resolution.

Constructor Summary

ObjectInputStream(java.io.InputStream inputStream)
Constructor

Method Summary

void	registerClass(java.lang.String className, java.lang.Class cls) Allows the caller to register a classname/class pair for use later during class resolution
protected java.lang.Class	resolveClass(java.io.ObjectStreamClass streamClass) Overrides the default behavior of java.io.ObjectInputStream.resolveClass such that requests for classes are satisfied by using a name-driven table lookup.

Method Detail

registerClass

public void registerClass(java.lang.String className,
                          java.lang.Class cls)
                   throws java.lang.IllegalArgumentException

Allows the caller to register a classname/class pair for use later during class resolution

Parameters:

className - The name of the class to register

cls - The class to register

Throws:

java.lang.IllegalArgumentException - Thrown if className is null or zero-length, or if cls is null.

resolveClass

protected java.lang.Class resolveClass(java.io.ObjectStreamClass streamClass)
                                throws java.lang.IllegalArgumentException,
                                       java.io.IOException,
                                       java.lang.ClassNotFoundException

Overrides the default behavior of java.io.ObjectInputStream.resolveClass such that requests for classes are satisfied by using a name-driven table lookup.

Overrides:

resolveClass in class java.io.ObjectInputStream

Parameters:

streamClass - The streamClass to be resolved.

Returns:

The class to which the streamClass arg was resolved.

Throws:

java.lang.IllegalArgumentException - Thrown if streamClass is null.

java.io.IOException - Thrown if IO error occurs.

java.lang.ClassNotFoundException - Thrown if class can't be resolved.
