... 03.500 82 Chapter 1 ­ Fundamentals You will notice at listing lines 53 through 57 that I chose to add some more records.  I just wanted to make things painfully obvious during the rest of the test.  There is nothing really magic about the values in those records, other than the fact they are easy to spot. Pay special attention to listing line 82.  Do you remember what I said earlier?  I deliberately left this line where it was to prove that statement.  Now, let's take a look at the output. roland@logikaldesktop:~/fuelsurcharge2$ javac doeHistory .java roland@logikaldesktop:~/fuelsurcharge2$ javac testpackDoeHistory .java roland@logikaldesktop:~/fuelsurcharge2$ java testpackDoeHistory ...  those records, then attempt to add three records which have the same primary key value. What happens? If you manage to get the records added, what happens when you attempt to reIndex()? How about when you try to undelete? 91 Chapter 1 – Fundamentals 1.13 1.131.13 1.131.13 1.13           Deleting and Packing Deleting and PackingDeleting and Packing Deleting and PackingDeleting and Packing Deleting and Packing I mentioned much of this information earlier but we are going to go over it again in detail because it tends to catch most newbies off­guard even after they have been told a hundred times. Deleting a record in an xBASE file does not physically delete the record (in most versions), nor does ...  The main menu/form for this application looks much like many other applications implementing the CUA (Common User Access) interface.  It has a main menu across the top, and those drop down when you click on the entries. 96 Chapter 1 – Fundamentals 20070905,289.3 20070912,292.4 20070919,296.4 20070926,303.2 20071003,304.8 20071010,303.5 20071017,303.9 20071024,309.4 20071031,315.7 20071107,330.3 20071114,342.5 20071121,341.0 20071128,344.4 Actually it has over 100 lines in it, but I'm certainly not going to print it here.  If you want, you can visit the Department of Energy Web site and pull down the spreadsheet which has historic diesel fuel prices, and create your own file. In theory I could have done the Util call found at listing line 17 inside of the doeHistory class, but I didn't have a warm and fuzzy feeling about the actual run­time scope of Util in all situations. Feel free to experiment on your own with placing this call at various places in the class hierarchy. Listing lines 26 through 78 serve no other purpose than to read a line from this CSV and load it as a record in the database.   Since I tried to implement localized error handling and provide meaningful error messages, this code is a lot larger than you will see in most examples which would simply trap all exceptions at one place and print a stack trace. We should discuss this code briefly for those who have never tried to read lines in from a text file before.  First you have to create a FileReader object as I did at listing line 33.  Once you have done that you can create a BufferedReader object to read from and buffer the FileReader object you just created as I did at listing line 40.  The second parameter (4096) is an optional buffer size in bytes.  If you do not pass a buffer size, there is some value which gets used by default.   One has to use a BufferedReader object if one wishes to read a line of input at a time as we do at listing line 46.  The readLine() method of a BufferedReader object ensures that we either get all characters as a String up to the newLine character or the end of the stream. ...

Memory and bandwidth issues simply cannot be overlooked when designing an application.  I provided only a few hundred records for our test database and I'm creating the files locally.  What happens when you modify this application to open a DBF and NDX which are on a Web site or remote file server?  Unless you are on dial­up, you probably have enough bandwidth to transfer fewer than 400 records.  How about when the file is approaching 2GB and the end user is on a satellite connection with a 120MB per day bandwidth restriction?  ... is a resource­intensive pig that imposes severe data access restrictions by requiring either exclusive access to the entire data set, or a live data monitor communicating with the database to monitor for any and all record changes. 102 Chapter 2 – Mega­Zillionaire Application 2.2 2.22.2 2.22.2 2.2 Supporting Classes Supporting ClassesSupporting Classes Supporting ClassesSupporting Classes Supporting Classes MegaDBF .java 1) package com.logikal.megazillxBaseJ; 2) 3) import java. io.*; 4) import java. util.*; 5) import org.xBaseJ.*; 6) import org.xBaseJ.fields.*; 7) ... intervening database engine locking all files and providing all access.  We don't have that, so we are already living   in   multi­user   Hell,   and   choose   to   handle   the  multi­user   problem...
