Reflective Middleware

The Case for Reflective Middleware

A multimedia streaming or videoconferencing application can obtain dramatic improvements in its quality of service by selecting a network transport protocol that suits the underlying network infrastructure (e.g., wireless LAN, wired LAN, or long distance Internet) and the available bandwidth.
Reconfigure the application to show the video in the larger display.
Select networking protocols, security policies, encoding algorithms, and various other mechanisms to optimize system performance for different contexts and situations.

Research directions in reflective middleware: the Lancaster experience - paper

Component frameworks - middleware platform is composed of a set of frameworks each of which represents some aspect of the required functionality or structure. E.g.,
- protocol frameworks
- dispatching of incoming calls
- resource management
- scheduling
These component frameworks accept ‘plug-in’ components that add or extend behaviour.
Component frameworks are themselves components, thus facilitating the construction of nested structures.
Reflection is then used to support introspection and adaptation of the underlying component/component framework structures.

Towards A Component-Based Middleware Framework for Configurable and Reconfigurable Grid Computing - paper

Grid middleware platforms have significant limitations as a Grid middleware support infrastructure.

Extremely limited, in comparison to object-based middleware platforms (e.g. RM-ODP and CORBA)
Little or no support for QoS specification and realisation
Does not include results from from advanced middleware research (reflective and component-based middleware technologies)

provision of generic services. E.g., CORBA supports generic reusable services like
- fault tolerance
- persistent state
- automated logging
- load-balancing
- transactional object invocation
- event distribution

Metaclasses and Reflection in C++

Not sure whether this always require you to insert meta-information into existing classes? The examples, suggest that, but the site doesn't explicitly mention it.

Reflection for C++

Two approaches
- Use debug information - needs to always compile in debug mode, might work only with gcc
- Programmer needs to provide meta information - intrusive
Contains a good comparison of different approaches

Non-intrusive object introspection in C++: architecture and application - paper

A separate meta object is defined for each class that completely captures information of the class for introspection purposes.
Maintains static offsets to class members
Friend functions are inserted into classes to obtain offsets of private members - instrusive
The meta class for class (Klass) must store
- the name of the class
- pointers to meta objects of its base classes
- methods to get names
- memory offsets of all its data members
- methods to get names and implementations of all its member functions (i. e., getMethod)
All objects are treated as pointers of type (void *)
