Class SymbianIoAdapter

java.lang.Object

com.db4o.io.IoAdapter

com.db4o.io.RandomAccessFileAdapter

com.db4o.io.SymbianIoAdapter

Deprecated.

Symbian is not supported anymore since 8.0

public class SymbianIoAdapter
extends RandomAccessFileAdapter

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)
