Hi,
We use either JDK or CGLib proxies in reference injections for java
components. It is a bit heavy and unnecessary for some cases. I now add
a simple optimization to inject the implementation instance directly if
the following criteria are met:
1) Both the source and target are java components
2) The binding is local SCA binding
3) The target implementation class implements/extends the source
interface/class
4) The target component scope is either STATELESS or COMPOSITE
5) There is only one invoker (JavaImplementationInvoker) in each
invocation chain for all the operations
What do you think?
Thanks,
Raymond
This kind of optimisation has always been part of the idea behind SCA,
so in general, I think this is fine.
There are probably a lot of wrinkles (Simon's note mentions some) and I
suggest that this should be prototyped and checked out before going into
the mainline code.
Yours, Mike.
