Examples of net.jini.io.MarshalOutputStream

net.jini.io.MarshalOutputStream
An extension of ObjectOutputStream that implements the dynamic class loading semantics of Java(TM) Remote Method Invocation (Java RMI) argument and result marshalling (using {@link RMIClassLoader}). A MarshalOutputStream writes data that is intended to be written by a corresponding {@link MarshalInputStream}.
MarshalOutputStream implements the output side of the dynamic class loading semantics by overriding {@link ObjectOutputStream#annotateClass annotateClass} and {@link ObjectOutputStream#annotateProxyClass annotateProxyClass} toannotate class descriptors in the stream with codebase strings obtained using {@link RMIClassLoader#getClassAnnotation RMIClassLoader.getClassAnnotation}.
MarshalOutputStream writes class annotations to its own stream; a subclass may override the {@link #writeAnnotation writeAnnotation} method to write the class annotations to adifferent location.
MarshalOutputStream does not modify the stream protocol version of its instances' superclass state (see {@link ObjectOutputStream#useProtocolVersion ObjectOutputStream.useProtocolVersion}). @author Sun Microsystems, Inc. @since 2.0
