Matthias Weßendorf commented on TRINIDAD-1757:
----------------------------------------------
Applying the actual decorator pattern just needs some extra lines in the
ConfigParser.
Check for the "right" constructor to delegate....:
-If no such constructor is there, we just use the class provided in the
trindiad-config.xml file, w/o decoration.
=> that way we have still backwards compatibility.
-Otherwise, we decorate and stick in ours to the one provided by the customer.
> Allow (or support) decorator pattern for the UploadedFileProcessor

> Reporter: Matthias Weßendorf

> Currently it is only possible to replace the entire UploadedFileProcessor,
> with a custom one.
> A neat improvement (crap, this should not be a bug) would be supporting the
> decorator pattern.
> The tricky part is that we need a buffer inside of the implementation of the
> file
> that get's passed into the Processor.
> currently you can call only once the "getInputStream", so we need a buffer
> here
> (that works with the impl's writeFile()/getInputStream()):
> There are some ways for that.
