Constructor Detail

RmiObjectInputStream

public RmiObjectInputStream(java.io.InputStream is,
                            NamingContext domain,
                            ContextFactory contextFactory)
                     throws java.io.IOException

Constructs a new RmiObjectInputStream.

Parameters:

is - the underlying input stream.

domain - the naming context to be used to decode the identifiers contained in Ref objects.

contextFactory - the context factory to be used to create hints for the bind method.

Throws:

java.io.IOException - if the super constructor throws an exception.

Method Detail

resolveObject

protected java.lang.Object resolveObject(java.lang.Object obj)
                                  throws java.io.IOException

Replaces Ref objects with corresponding stubs. This method uses the domain to decode the identifier encoded in a Ref object, and then uses the bind method of the decoded identifier to get a stub corresponding to this identifier. The type stored in the Ref object is passed as an hint to the bind method.

Overrides:

resolveObject in class java.io.ObjectInputStream

Parameters:

obj - an object.

Returns:

a stub if obj is a Ref object, or obj otherwise.

Throws:

java.io.IOException - if a Ref object cannot be replaced with a stub.

resolveClass

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

Overrides:

resolveClass in class java.io.ObjectInputStream

Throws:

java.io.IOException

java.lang.ClassNotFoundException
