Constructor Detail

ContextObjectInputStream

protected ContextObjectInputStream()
                            throws java.io.IOException,
                                   java.lang.SecurityException

Construct a default instance of the context aware object input stream.

Throws:

java.lang.SecurityException - if an active security manager prevents subclassing

java.io.IOException - for IO errors.

ContextObjectInputStream

public ContextObjectInputStream(java.io.InputStream in)
                         throws java.io.IOException

Construct a context aware object input stream using the specified input stream.

Parameters:

in - The associated input stream.

Throws:

java.io.IOException - for IO errors reading from the stream.

Method Detail

resolveClass

protected java.lang.Class<?> resolveClass(java.io.ObjectStreamClass desc)
                                   throws java.io.IOException,
                                          java.lang.ClassNotFoundException

Overrides:

resolveClass in class java.io.ObjectInputStream

Parameters:

desc - The object stream class description.

Returns:

The associated class.

                                        throws java.io.IOException,
                                               java.lang.ClassNotFoundException

Resolve the proxy class using the active context.

Overrides:

resolveProxyClass in class java.io.ObjectInputStream

Parameters:

interfaces - The interfaces associated with the proxy.

Returns:

The associated class.

Throws:

java.lang.ClassNotFoundException - if an interface cannot be found.
