Summary

The order in which your readmulti operation methods are called is:

• pre - always called once before anything else;
• first - called once with the first record, provided at least one record exists;
• filter - called for each record (including the first);
• operation - called for each record for which filter returns true;
• post - always called once after everything else;
• getMaximum - specifies the maximum number of records that should be matched.

If you are designing processing that maintains locks remember that there are performance implications when you do so.
