Florian Müller commented on CMIS-240:
-------------------------------------
This is for convenience.
The list that is returned by getProperties() contains not only the property
values but also the data type, display name, query name, etc. of each property.
If it would just a return a Map<String, ?> the application would have to fetch
this information from the type system. That would be an often repeated pattern
that can be covered by the framework.
updateProperties(), on the other hand, only requires the id and the value of
the properties that should be updated. Creating complete Property<?> objects
for this is very inconvenient for applications. Creating a Map<String, ?> is
easy.
There should be no need to convert the output of getProperties() into something
that updateProperties() accepts. Most of the standard properties a read-only,
anyway. Usually the application knows which properties have to be updated. Only
set those in the Map.

> The method CmisObject.getProperties() returns List<Property<?>> but for
> setting properties with CmisObject.updateProperties(Map<String,?> properties)
> I need another type Map<String,?>. Why are there two different types and how
> to convert one type into another?
