Carsten Ziegeler commented on COCOON-1984:
------------------------------------------
The delegating is done as this class implements both, Parameters and Map, and
should provide the same values as the wrapped parameters object. We could avoid
delegating with the cost of copying the information from the original
parameters object to this one. Because of performance we chose to use
delegation instead.

> Key: COCOON-1984
> URL: https://issues.apache.org/jira/browse/COCOON-1984
> Project: Cocoon
> Issue Type: Bug
> Components: * Cocoon Core
> Affects Versions: 2.2-dev (Current SVN)
> Reporter: Mark Lundquist
> Assigned To: Carsten Ziegeler
> Priority: Minor
>
> ...and as a result, the object displays as empty, e.g. when debugging in
> Eclipse. I added
> public String toString() {
> return wrappedParameters.toString();
> }
> and that fixed it. Although, I am puzzled as to why this class both extends
> the Avalon Parameters class and is implemented using a delegate
> ('wrappedParameters') of that type. Why is not extending Parameters enough?
> The delegate seems like an unnecessary complication.
