Class | Description |
---|---|
IoAdapter | Base class for database file adapters, both for file and memory databases. |
MemoryIoAdapter | IoAdapter for in-memory operation. |
RandomAccessFileAdapter | IO adapter for random access files. |
SymbianIoAdapter | Workaround for two I/O bugs in Symbian JDK versions: - seek() cannot move beyond the current file length. Fix: Write padding bytes up to the seek target if necessary - Under certain (rare) conditions, calls to RAF.length() seems to garble up following reads. Fix: Use a second RAF handle to the file for length() calls only. Usage: Db4o.configure().io(new com.db4o.io.SymbianIoAdapter()) TODO: - BasicClusterTest C/S fails (in AllTests context only) |
VanillaIoAdapter | base class for IoAdapters that delegate to other IoAdapters (decorator pattern) |
