Subject [jira] Commented: (COCOON-1984) o.a.c.environment.TemplateObjectModelHelper.ParametersMap does not override toString()
Date Tue, 13 Feb 2007 10:24:06 GMT


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.

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.
