class CapTPReplacer

extends Replacer

Used to specialize the SerializationStream for encoding a reference over a CapTP connection.

When our run method returns an ObjectRefDesc, the corresponding decoded object is not simply this ObjectRefDesc. It is this ObjectRefDesc as dereferenced by CapTPReviver.
