Storage class used to provide persistence.




The value of this element is a class name.


This element specifies the storage class that provides persistence for this class.

The %Library.CacheStorage class is the default storage class and provides the default storage structure.

The %Library.CacheSQLStorage class is used for mapping classes to legacy data structures.

For serial (embedded) classes, this must be set to %Library.CacheSerialState (which is set automatically by the New Class Wizard).

Default Value

The default value for the <Type> element is %Library.CacheStorage.
