Deepal Jayasinghe commented on AXIS2-4881:
------------------------------------------

I would not consider this as a blocker.  In addition, it would be great if we 
can find a good usecase for this feature, otherwise we do not need to fix this 
for 1.6 release. 

> Added invoke_stage1 and invoke_stage2 methods to AbstractHandler

>             Project: Axis2
>          Issue Type: Bug
>            Reporter: Rich Scheuerle
>            Priority: Blocker
>   Original Estimate: 24h
>  Remaining Estimate: 24h

> Background:
> The AbstractHandler class exposes an invoke() method that Handlers override 
> to provide the specific invoke code.
> Problem:
> Many Handlers actually have 2 stages of logic.  The first stage simply does 
> some quick processing to determine if the handler should be called.  The 
> second stage does the actual work.
> Because there is only one invoke method, these separate stages of processing 
> get lumped together.
> Solution:
> Provide an alternative (optional) invoke semantic.
> A Handler can choose to override the new invoke_stage1 and invoke_stage2 
> methods.
> All current Handlers will continue to work.  The existing invoke() method is 
> retained.
