Doc on how to use context
-------------------------
Key: TUSCANY-463
URL: http://issues.apache.org/jira/browse/TUSCANY-463
Project: Tuscany
Type: Task
Components: C++ SCA
Versions: Cpp-current
Reporter: Ed Slattery
Priority: Minor
Fix For: Cpp-current
The documentation for use of SCA should make it clear that the component
context is not available on the constructor of the service, so we must not
attempt to store references to other services by locating them in the
constructor - it wont work.
We must also not have a lazy initialize which stores the services on first use
- that doesnt work because they reference the context, which is destroyed on
exit from the lazy initialization.
Also, you cant store the context as a member variable, as it cant be
instantiated by a default constructor.
Bottom line - locate your services in the method in which you use them. Thats
a good idea because of a later need of hot replace of service wiring anyway.
