Ruwan Linton commented on AXIS2-4881:
-------------------------------------
Shall I go ahead and try to fix this properly?? I think having a separate
method to implement the conditional decision of whether this handler needs to
be invoked or not outside of the invoke method is a good thing to have, but
this fix requires a lot of work, to reach there.
> Added invoke_stage1 and invoke_stage2 methods to AbstractHandler

> Key: AXIS2-4881
> URL: https://issues.apache.org/jira/browse/AXIS2-4881
> 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.
