Class OneWireSensorInclude

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          com.qindesign.servlet.example.OneWireSensorInclude

All Implemented Interfaces:

Servlet, ServletConfig

Direct Known Subclasses:

ADInclude, FamilyCode20Include, PotentiometerInclude, SwitchInclude, TemperatureInclude

public abstract class OneWireSensorInclude
extends HttpServlet

The purpose of this class is to provide a base-point for handling specific 1-Wire containers that extend from OneWireSensor. This does a few basic things:

• Checks that this is a valid 1-Wire sensor request by confirming that there is a OneWireContainer being passed by the request.
• Prints a basic header that describes the 1-Wire device.

This is designed to work with the OneWireServlet example.

Method Detail

doPost

protected final void doPost(HttpServletRequest req,
                            HttpServletResponse resp)
                     throws ServletException,
                            IOException

Processes a POST request. This calls doGet.

Overrides:

doPost in class HttpServlet

Throws:

ServletException

IOException

doGet

protected final void doGet(HttpServletRequest req,
                           HttpServletResponse resp)
                    throws ServletException,
                           IOException

Processes a GET request. Subclasses need to implement the doContainerGet method to process a request.

Overrides:

doGet in class HttpServlet

Throws:

ServletException

IOException

doContainerGet

protected abstract void doContainerGet(OneWireContainer c,
                                       HttpServletRequest req,
                                       HttpServletResponse resp,
                                       ServletOutputStream out)
                                throws IOException,
                                       OneWireException

Performs the include just after printing the header. This is the method that subclasses need to implement in order to processes a request.

Throws:

IOException

OneWireException
