[ApacheDS][ACDFEngine] Why are we passing NextInterceptor to engine?

[Alex Karasulu <ao...@bellsouth.net>]

Trustin,

I'm trying to understand why we need to pass the reference to the next 
interceptor into the ACDF engine's check and hasPermission methods?  
Reason I ask is because all we need to do is throw an LdapNoPermission 
exception and we exit the stack.  Is there something I'm missing?

Thanks,
Alex

ProtectedItem.MaxImmSub requires the access to the DIT because it limits the
number of siblings. We cannot simply use ContextPartition because it
bypasses all next interceptors in the chain. That's why we need
NextInterceptor to implement ACDF.

Sorry I still cannot understand why you need the interceptor.  Can you 
tell me what you do with the interceptor?

Please take a look at MaxImmSubFilter. It is the only place actually
requires NextInterceptor. ProtectedItem.MaxImmSub limits the maximum number
of immediate subordinates.
