I don't believe we can, when working with security you can have users that
are only allowed to
read, either because of higher level security or database level security,
the customary way
to tell read only and writable in GeoTools is to have the object implement
either FeatureSource
or FeatureStore.
If you want to change the library conventions you can go through the
proposal process and then
change all of the library to follow suite. I just don't want to have yet
another inconsistency around.
The original names were associated to interfaces that were meant to be
published in
main once the work stabilized, there was nothing "internal" about them, I
just did not push
them into core because we missed the other two implementations to vet them.
http://svn.osgeo.org/geotools/trunk/modules/unsupported/postgis-versioned/src/main/java/org/geotools/data/VersioningDataStore.java
http://svn.osgeo.org/geotools/trunk/modules/unsupported/postgis-versioned/src/main/java/org/geotools/data/VersioningFeatureStore.java
http://svn.osgeo.org/geotools/trunk/modules/unsupported/postgis-versioned/src/main/java/org/geotools/data/VersioningFeatureSource.java
GeoServer WFS-V and GSS modules explicitly work with these interfaces, and
in GeoServer core there
is a dynamic check for their names using the class name, see here:
http://svn.codehaus.org/geoserver/trunk/src/main/src/main/java/org/geoserver/catalog/ResourcePool.java
and search for "versioning" inside of it
