| Blob.java | Interface | the db4o Blob type to store blobs independent of the main database
file and allows to perform asynchronous upload and download operations.
Usage:
- Define Blob fields on your user classes.
- As soon as an object of your class is stored, db4o automatically
takes care that the Blob field is set.
- Call readFrom to read a blob file into the db4o system.
- Call writeTo to write a blob file from within the db4o system.
- getStatus may help you to determine, whether data has been
previously stored. |
| Db4oCollection.java | Interface | |
| Db4oCollections.java | Interface | factory and other methods for database-aware collections. |
| Db4oList.java | Interface | db4o List implementation for database-aware lists.

- newly added objects are automatically persisted.
- list elements are automatically activated when they are needed. |
| Db4oMap.java | Interface | db4o Map implementation for database-aware maps.
A Db4oMap supplies the methods specified in java.util.Map.
All access to the map is controlled by the
com.db4o.ObjectContainer ObjectContainer to help the
programmer produce expected results with as little work as possible:
- newly added objects are automatically persisted.
- map elements are automatically activated when they are needed. |
| Db4oType.java | Interface | marker interface for all special db4o types. |
| SecondClass.java | Interface | marks objects as second class objects. |
| TransientClass.java | Interface | Marker interface to denote that a class should not be stored by db4o. |
| Unversioned.java | Interface | |
