Context

Synopsis

Context objects contain a list of properties, stored as NamedValue objects, that are passed along with method requests to indicate properties of the client context. Every ORB has a default context, accessed using the ORB.get_default_context() method. Contexts can be linked in a hierarchy of contexts. If a search for a property is made on a Context object and the search within the object fails, then the search is continued in the parent Context, and so on until the root context is reached. You can create a new child of a Context using its create_child() method. Other methods on the Context class let you get, set and delete values from the Context.
