Re: [morph-user] Adapting legacy request parameters into new POJO?

[Matt B. <gud...@gm...>]

Hi, Mick.  Now that we're in the proper forum, let me apologize for
the state of Morph's documentation, but you can certainly appreciate
the universal axiom that documentation is always the lowest priority
for an OSS project, being the least fun of the necessary tasks.
DelegatingCopier has most likely become SimpleDelegatingTransformer
(SDT) in the net.sf.morph.transform.transformers package.  Also, SDT's
default constructor initializes it with a best-guess at an all-purpose
set of delegate Transformers for a simple object graph.  I would try
one of those out of the box unless you already know you have very
complex types to work with here.  If these are all strings, you should
pretty much be set.

HTH,
Matt
