| 25 | * This class describes a persistable class. This is a finer grained |
| 26 | * thing than static classes, because the library allows for dynamic |
| 27 | * classes (classnames) to be created. So an unambigous description of |
| 28 | * a persistable class is it's class, and the dynamic name.<br> |
| 29 | * If the dynamic name is not given, the class is considered a static |
| 30 | * class, these are the normal Java classes. If the dynamic name is |
| 31 | * given, the class is considered a dynamic class, which has no |
| 32 | * actual class in the JVM, but it's also considered a subclass of the |
| 33 | * root static class contained. |
