Hi there!
Here are some structural evolutions I'd like to discuss before any
coding. I'm pretty sure that the first one is a good option - the second
one is more prospective.
1. On-demand tools loading: instead of a standard HashMap, the idea here
is to have a ToolMap, inheriting HashMap, which will instanciate a tool
from its toolinfo only when the generic getter is called. This should be
a quite interesting performance gain in some situations. We maybe need
some attribute to have tools instanciated at toolbox initialization
('instanciate-on-load' ?).
2. View tools: other objects in my webapp are often jealous of the view
servlet. They also would like to use some of the tools. Session scoped
tools can be reached via the session, but it's not the case for
application or request scoped tools. To achieve this, there would be two
things to do:
- the application tools map should be stored as a ServletContext
attribute and the request tools map as a Request attribute.
- the constitution of the three scoped maps should be decorrelated from
the remaining of the processing so that it could potentially take place
in a servlet filter.
Thanks for your remarks,
Claude
