Soldering the components onto the PCB follows the same procedure we have already discussed. There is an area on the board in which you can add your custom circuitry, too. The kit also comes with a connector that can be used to interface the board to other circuitry. Unlike the breadboard PCB, the prototype area holes are not connected together in strips. You have to add short pieces of bare copper wire or create solder bridges to tie holes together. Figure A-21 shows the connector area in which the eight digital I/O pins are connected along with power and ground. Although it is labeled 5V, this is really the 4.3V supply.

You define structs in a similar manner to classes. The keyword class is replaced with struct. The main difference between a class and struct is the area of memory where the object will be allocated. When used as a local variable or parameter, a struct is allocated on the stack, while a class is allocated on the managed heap. Because structs are allocated on the stack, they are not garbage collected but are automatically deallocated when a function exits. It is generally slightly faster accessing their fields and slightly slower passing them to methods, but these differences do tend to be quite small. Because they are allocated on the stack, it is generally best to create structs with a small number of fields to avoid stack overflow. You can t use inheritance when implementing structs, so this means structs can t define virtual methods or abstract methods. The next example defines a struct representing an IP address. Note the only difference from defining a class is that the keyword struct is used.

A value of true instructs Taconite to parse the specified content into JavaScript on the server and to send the JavaScript back to the browser embedded within the response XML A false value indicates that the parsing of the content to JavaScript will occur on the browser It should now be clear why the weather forecast was split into so many separate JSP files The main weatherForecastjsp file renders the weather forecast component the first time the entire Ajax Dashboard page is rendered The weatherForecastAjaxjsp file handles the Ajax updates of the forecast component Both JSPs need to render the forecast location and the forecast itself You want to avoid writing duplicate code, so the forecast location and forecast table are separated into their own JSP files, which are included into the weatherForecastjsp and weatherForecastAjaxjsp files.

type IpAddress = struct val first : byte val second : byte val third : byte val fourth : byte new(first, second, third, fourth) = { first = first; second = second; third = third; fourth = fourth } override x.ToString() = Printf.sprintf "%O.%O.%O.%O" x.first x.second x.third x.fourth member x.GetBytes() = x.first, x.second, x.third, x.fourth end So, when should you use a classes, and when should you use a struct A good rule of thumb is to avoid structs, using them only when really necessary, for example, when interoperating with unmanaged C/C++ code (for more details on this, see 13).

Figure A-21. PCF8574 connector area Figure A-22 shows the completed board. In 13, we used this prototype board with a 16button matrix to make a small keypad input for the NXT. Figure A-22. Finished PCF8574 PCB

In this way, updating the forecast location or the forecast table will automatically be the same whether it s rendered when the Ajax Dashboard first loads or whether it s updated by an Ajax request What exactly is the output of the weatherForecastAjaxjsp file Listing 8-8 shows an example of the XML response rendered by weatherForecastAjaxjsp and returned to the browser..
