Description

The meta-data-related methods in PersistenceManagerFactory work with Strings (fully qualified class-names) instead of classes. This includes the new method requested in JDO-667.

However, to actually do sth. (e.g. create a new query or get an extent), a java.lang.Class is required. In some environments (e.g. OSGi), class-loading is not trivial and it is therefore not so easy to get the right java.lang.Class (i.e. the same as used by the JDO implementation) for a certain class-name.

Since the JDO implementation needs to be able to load the right classes, anyway, the class-loading must already be solved somehow (e.g. by an OSGi-aware class-loader). It should therefore be easy to expose the method used by the JDO implementation for class-loading.

For these reasons, I kindly request the following new method in PersistenceManagerFactory:

Class<?> getManagedClass(String className)
