This document provides all the information required to run the OpenORB Property Service. In particular, it explains how to install, configure and test this service.

Chapter 1. Overview

CORBA Object are not really typed except by interface description. However, two objects that implement the same interface are of the same type !

The Property Service provides an easy way to specify extra information about an object. Properties are typed, named values dynamically associated with an object, outside of the type system.

The property service implements objects supporting the PropertySet interface or the PropertySetDef interface. The PropertySet interface supports a set of properties. A property is two tuple of: property_name and property_value

  • property_name is a string that names the property,
  • property_value is of type any and carries the value assigned to the property.

The PropertySetDef interface is a specialization (subclass) of the PropertySet interface that exposes the characteristics (or metadata) of each property (e.g., readonly or read/write access).
