Detailed Description
Class to access a communication object.
Is returned by querying a channel, the most common way to get these is by creating a DCOWriter.
This class implements introspection-based access to DCO objects. If you have a void pointer and know the classname, this can also be created directly.
Based on either the name of the data member, or on the index of a data member (as returned by the DataClassRegistry::getMemberIndex call) you can create an ElementWriter. With such a writer the members of the encapsulated object can be manipulated.
