* Returns an array of record numbers that match the specified * criteria. Field n in the database file is described by * criteria[n]. A null value in criteria[n] matches any field * value. A non-null value in criteria[n] matches any field * value that begins with criteria[n]. (For example, "Fred" * matches "Fred" or "Freddy".)
if my criteria = "abc", in my record, i have 2 fields from 2 records
1. abcedf 2. eeeabce
i believe that the first one is correct.
but how about "eeeabce", it does not match from beginning, so should i consider it as valid feild?
* Deletes a record, making the record number and associated disk * storage available for reuse. * Throws SecurityException if the record is locked with a cookie * other than lockCookie. public void deleteRecord(long recNo, long lockCookie)throws RecordNotFoundException, SecurityException
so delete method actually does not delete the record info, but it overwrite the 00 by using 0x800. the record file is retrievable!
am i right?
