Constructor Detail

RmiObjectOutputStream

public RmiObjectOutputStream(java.io.OutputStream os,
                             NamingContext domain)
                      throws java.io.IOException

Constructs a new RmiObjectOutputStream.

Parameters:

os - the underlying output stream.

domain - the naming context to be used to export local interface references, to make them remotely accessible.

Throws:

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

Method Detail

replaceObject

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

Replaces component interfaces with Ref objects. If the given object is an Interface, two cases are possible. If the object is also a Reference, then it is replaced with a Ref object containing an encoded form of the identifier held by the Reference. If the object is not a Reference, then it is exported with domain, and replaced with a Ref object containing an encoded form of the Identifier returned by export.

Overrides:

replaceObject in class java.io.ObjectOutputStream

Parameters:

obj - an object.

Returns:

a Ref object if obj is a component interface, or obj otherwise.

Throws:

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

drain

protected void drain()
              throws java.io.IOException

Drain any buffered data in this stream.

Overrides:

drain in class java.io.ObjectOutputStream

Throws:

java.io.IOException - if an IO exception occurs.
