Some questions about the basic classes for data reads and log writes

As what we discussed in the "incremental checkpointing issue" before,
I need to gather the runtime disk I/O information. So, I need to monitor
the data reads and log writes. So far, I found the basic classes to do data
reads are :
  org.apache.derby.impl.store.raw.data.RAFContainer.java
  org.apache.derby.impl.store.raw.data.InputStreamContainer.java
the basic class to do log writes is :
  org.apache.derby.impl.store.raw.log.LogAccessFile.java

Is there any other classes is involved in data reads and log writes?

Thanks.


Raymond
