Constructor Detail

ResolvingObjectInputStream

public ResolvingObjectInputStream(InputStream stream,
                                  ClassLoader loader)
                           throws IOException

Create an ObjectInputStream that reads from the specified InputStream using the specified ClassLoader to resolve classes.

Parameters:

stream - the underlying InputStream from which to read

loader - the ClassLoader to use for class resolution

Throws:

IOException - if an exception occurred in the underlying stream.

Method Detail

resolveClass

protected Class resolveClass(ObjectStreamClass descriptor)
                      throws IOException,
                             ClassNotFoundException

Load the local class equivalent of the specified stream class description.

Overrides:

resolveClass in class ObjectInputStream

Parameters:

descriptor - serialization descriptor for a class

Returns:

a Class object corresponding to descriptor

Throws:

IOException - if an exception occurred in the underlying stream.

ClassNotFoundException - if the corresponding class cannot be found.
