Hi Prashant,

The methods added to the reflection package were to support storing aliases
(for class mappings) and also retrieving the class based on the stored
alias.

In the patient case the local alias would also be "org.blazeds.vo.Patient"

I am not familiar with the approach you are using for deserializing the amf
in js, but I expect the general approach should be something like this:

a) identify the alias from the inbound amf data (seems like the
_explicitType field in your data)
b) retrieve the local class that corresponds to that alias and instantiate
an instance using getClassByAlias method from the _explicitType value:  var
classToInstantiate:Class = getClassByAlias("org.blazeds.vo.Patient");
This class should have been already registered using registerClassAlias at
some earlier point in time.
c) populate the fields of that typed instance based on the value of the
fields during deserialization. Ideally this should happen during
deserialization directly into the new typed instance instead of creating
one generic object during deserialization and then using it to subsequently
populate the typed instance.

If you are using a 3rd party library then unless it has support for the
explicitType mappings (to retrieve from getClassByAlias) perhaps you will
need to work from the object structure with the _explictType fields and
recreate the typed object structure from it (again, it would be helpful if
the library had some sort of mapping to avoid this 'double handling'). This
could be more complicated if the inbound amf has instances with nested
custom class fields, but should be straightforward for basic value object
type scenarios (as per your Patient example).


Hopefully that makes sense.... let me know if I can clarify any of the
above.


cheers,
Greg
