'''Description:'''
+
=web=
-
The Shop is the central class of a SalesPoint application. You can run Processes on the Shop itself, you can add SalesPoints where you can run Processes too. The Shop provides a central MenuSheet, where important actions could be invoked (save, load, quit etc.). You may wish to change this MenuSheet in order to open SalesPoints or to offer additional user interaction.
+
-
All sorts of central data should be stored here, like Catalogs, Stocks, Currencys, MoneyBags, UserManagers and other attributes that are of global use.
+
-
It is important to make a singleton instance of Shop and declare it with the static Shop.setTheShop() method. If you need the Shop instance, call Shop.getTheShop(). Don´t try to use the instance, you can get in your Shops methods, because very unlovely runtime errors may be the result.
+
-
 
+
-
'''ToDo:'''
+
-
 
+
-
# Create a subclass of Shop.
+
-
# Add constructor to create singleton instance of Shop. You can initialize some data in the constructor
+
-
# For invoking the Shop, create a simple class with the public static void main (String[] noArgs) method.
+
-
# Therein create an instance of the Shop and initialize its attribute of the singleton Shop instance by the setTheShop(Shop TutorialShop) method. Furthermore call the start() method to start the Shop.
+
-
#The main class is also used to add a SalesPoint (or even more) to the Shop here.

-
This is required whenever reaction on adding or removing SalesPoints is needed, such as manipulating menus or notifying SalesPoints already opened.
+
-
 
+
-
'''ToDo:'''
+
-
 
+
-
# Open the designated Shop class.
+
-
# Override the protected void onSalesPointAdded() and/or protected void onSalesPointRemoved() methods to react on the adding or removing. Be sure to synchronize your method with the one of the original Shop by first calling it's super.onSalesPoint....

====Implement a SalesPoint====
+
-
 
+
-
'''Description:'''
+
-
The SalesPoint is a part of the Shop. A Shop usually consists of one SalesPoint at least. SaleProcesses take place at a Point of Sale in most cases. They could be startet easily with the public void runProcess(SaleProcess p) method.
+
-
The SalesPoint appeares in a seperate Frame, a JDisplayFrame. In the JTabbedPane of the Shop appeares the SalesPoints StatusDisplay. It could be used for different purposes.
+
-
The FormSheets could be both added with MenuSheets, which could be used to start Processes or to open other SalesPoints or to close them.
+
-
 
+
-
'''ToDo:'''
+
-
 
+
-
# Create a class that extends SalesPoint
+
-
# Add the class constructor. You can also set the SalesPoints frame size here for example.
+
-
# Implement protected FormSheet getDefaultFormSheet() to define the SalesPoints FormSheet. Change the FormSheet content by adding a FormSheetContentCreator. This can be done by creating a subclass of FormSheetContentCreator.
+
-
# Implement protected MenuSheet getDefaultMenuSheet() to define the SalesPoints MenuSheet.

====Change quit behaviour====
+

-
 
+
-
'''ToDo:'''
+
-
 
+
-
# Open the designated SalesPoint class.
+
-
# Implement the protected boolean onCanQuit() method to change the quit behaviour. The return of true will close the SalesPoint against the return of false will keep the SalesPoint opened.

===Processes===
+
-
 
+
-
====Implement a SalesProcess====
+
-
 
+
-
'''Description:'''
+
-
SalesProcesses are the implementation of a deterministic finite automat. It shall be deemed to be a vectored graph with nodes called Gates and edges called Transitions. Make sure that user interaction only takes place in Gates while Transitions should be rather short without any user interaction. The reason is that a Process could only be suspended at a Gate and so the Shop is only able to persistify the Process at a Gate.
+
-
Often the display of a Gate is to be influenced by the user interaction before. In this case, Gates should be prepared with a Transition leading to this Gate. SaleProcesses could be startet in the Shop itself, but in most cases Processes take place in a SalesPointFrame and are startet from the SalesPoint.
+
-
 
+
-
'''ToDo:'''
+
-
 
+
-
# Create a subclass of SalesProcess.
+
-
# Add the constructor and therein call the super method to inherit from the Superclass, the SaleProcess. You can add any attribute to the constructor, most common is the Process' name.
+
-
# Every Process needs a starting Gate, the getInitialGate(). Add this method to the SaleProcess.
+
-
Define the UIGate itself and add the necessary FormSheet etc. (see related topics). A basic implementation of SaleProcess is now done.
+
-
# To start the SaleProcess you can add a button to your SalesPoint's FormSheet and therewith lead to an action that runs the Process on your SalesPoint. Therefore an action was defined that runs any SalesProcess on a SalesPoint by passing the relevant process and a possible necessary DataBasket. (This structure was for example used in the "[[Videoautomat]]" tutorial).

+
-
# Choose the SaleProcess you want to modify.
+
-
# implement the method protected void onFinished().
+
-
# add the code that should be run on quiting the process to the newly created method.
+

====Change start behaviour====
+
-
 
+
-
'''Description:'''
+
-
If a Process should have a certain task after being resumed or started, you have to change its start behaviour.
+
-
Therefore overwrite the method onResumeOrStart().
+
-
 
+
-
'''ToDo:'''
+
-
 
+
-
Choose the SaleProcess you want to modify.
+
-
Implement the method protected void onResumeOrStart(boolean fIsResume).

-
====Define a UIGate====
+
-
 
+
-
'''Description:'''
+
-
Gates are a part of SalesProcesses. In contrast to normal Gates, UIGates are made for user interaction and can display FormSheets and MenuSheets. If you need to display something, use UIGates. Use JOptionPanes or JDialogs only to display short user interaction and information, because after serialisation they won´t be restored.
+
-
If you want to incorporate a UIGate not as StartGate, it may be mandatory to affect the view of the UIGate during Process. In this case, you have to use a Transition.
+
-
 
+
-
'''ToDo:'''
+
-
 
+
-
# Select the SaleProcess where you want to define your UIGate.
+
-
# Implement a method that returns a Gate as the class UIGate implements Gate.
+
-
# Create an instance of UIGate. Set the attributes to null as they will be set later.
+
-
# Define a FormSheet for the UIGate and add a FormSheetContentCreator that modifies the FormSheet.Use any FormSheet-Class and modify the FormSheetContentCreator and possible data accordingly.Available FormSheet-Classes are: LogOnForm, LogTableForm, MsgForm, SingleTableFormSheet, TextInputForm, TwoTableFormSheet, UserTableFormSheet.
+
-
# Assign the recently instantiated FormSheet to the UIGate.
+
-
# Return the instance of UIGate.
+
-
 
+
-

</code>
+
-
 
+
-
====Define a Gate====
+
-
 
+
-
'''Description:'''
+
-
Gates are a part of SalesProcesses. If you want to implement user interaction, use UIGates. Normal Gates are preferably used to decide at which UIGate the Process continues. They are also very suitable for the implementation of background Processes. If you need data to prepared before the Gate goes into action, implement a Transition to the Gate.
+
-
 
+
-
'''ToDo:'''
+
-
 
+
-
# Select the SaleProcess where you want to define your Gate.
+
-
# Implement a method that returns a Gate.
+
-
# Instantiate the Gate and add the needed public Transition getNextTransition(SaleProcess process, User user) throws InterruptedException method.
+
-
# Add your code that selects the next GateChangeTransition.
+
-
# Return the Gate.
+
-

====Define a Transition====
+
-
 
+
-
'''Description:'''
+
-
Transitions main task is to prepare Gates while the application is running. The idea is to manipulate the view of a Gate in order to react to user interaction or collected data of the past. It is possible to prepare normal Gates and UIGates as well.
+
-
 
+
-
'''ToDo:'''
+
-
 
+
-
# Create a class that implements Transition.
+
-
# In this class add the public Gate perform(SaleProcess process, User user) method. It's the place where the actions between two gates will be defined.
+
-
# Add your code to this method and return the Gate that will be the next target. Therefore you should cast the SaleProcess in the perform method to your Process class that currently calls the Transition. Then simply return the needed Gate from there.
+

====Define Transition that just changes to a Gate====
+
-
 
+
-
'''Description:'''
+

During a running Process it may be volitional to change just to a Gate. This could be a not user interactive Gate, which has no Transition leading to it. It could be also an already prepared UIGate, to which you want to change after a "Back"-Button, when it should be not refreshed by the Transition. This might be the case, when the user interaction should be not erased.

'''ToDo:'''
+
-
 
+
-
# Use constructor of class GateChangeTransition: Transition t = new GateChangeTransition(Gate gTarget);.
+
-
 
+
-
'''Example Source Code:'''
+
-
<code java>
+
-
// ...
+
-
    Gate tmpGate0 = new Gate()
+
-
        {
+
-
            public Transition getNextTransition(SaleProcess process, User user)
+
-
                throws InterruptedException
+
-
            {
+
-
                return new GateChangeTransition(targetGate);
+
-
            }
+
-
        };
+
-
// ...
+
-
</code>
+

+

====Define Transition that changes to a special Gate====
+
-
 
+
-
'''Description:'''
+
-
There are six predefined Process Gates. All of them except the ErrorGate have a predefined Transition, leading to it.
+
-
 
+
-
# If you need the singelton instance of a special Process Gate, use the get-method of class SaleProcess:<br />getCommitGate()<br />getErrorGate(int nErrorNesting) <br />getLogGate() <br />getRollbackGate() <br />getStopGate() <br />getQuitGate()
+
-
#If you need a Transition, leading to a special Process Gate, use the static attributes of class GateChangeTransition:<br />GateChangeTransition.CHANGE_TO_COMMIT_GATE <br />GateChangeTransition.CHANGE_TO_LOG_GATE <br />GateChangeTransition.CHANGE_TO_ROLLBACK_GATE <br />GateChangeTransition.CHANGE_TO_STOP_GATE <br />GateChangeTransition.CHANGE_TO_QUIT_GATE
+
-
 
+
-
'''Example Source Code:'''
+
-
<code java>
+
-
// ...
+
-
    Gate tmpGate1 = new Gate()
+
-
        {
+
-
            public Transition getNextTransition(SaleProcess process, User user)
+
-
                throws InterruptedException
+
-
            {
+
-
                return GateChangeTransition.CHANGE_TO_QUIT_GATE;
+
-
            }
+
-
        };
+
-
// ...
+
-
</code>

===Time Management===
+
-
 
+
-
====Incorporate a Timer====
+
-
 
+
-
'''Description:'''
+
-
A Timer is able to manage the current time in your application. A Timer needs a Time Object to be referenced on.
+
-
If you want to react to different TimerEvents, you will have to incorporate a TimerListener.
+
-
Time management in SalesPoint Framework is abutted on several Java classes:
+
-
<br />[http://java.sun.com/j2se/1.4.2/docs/api/java/util/Calendar.html java.util.Calendar]
+
-
<br />[http://java.sun.com/j2se/1.4.2/docs/api/java/util/GregorianCalendar.html java.util.GregorianCalendar]
+
-
<br />[http://java.sun.com/j2se/1.4.2/docs/api/java/util/Timer.html java.util.Timer]
+
-
<br />[http://java.sun.com/j2se/1.4.2/docs/api/java/util/TimerTask.html java.util.TimerTask]
+
-
<br />[http://java.sun.com/j2se/1.4.2/docs/api/java/util/TimeZone.html java.util.TimeZone]
+
-
<br />[http://java.sun.com/j2se/1.4.2/docs/api/java/sql/Timestamp.html java.sql.TimeStamp]
+
-
 
+
-
'''ToDo:'''
+
-
 
+
-
# Create a new instance of Time. In this case CalendarTime is used. Set the time interval.
+
-
# Create a new instance of Timer. In this case AutoTimer is used.
+
-
# If you need, add a TimerListener and add the methods the class must inherit from the base class. Add your code to react to the events.
+
-
# Finally start the timer.
+
-
 
+
-
'''Example Source Code:'''
+
-
<code java>
+
-
  1
+
-
        // initialize with current system time and increase time by second
+
-
        CalendarTime calendarTime = new CalendarTime();
+
-
        calendarTime.setTimeToCount(CalendarTime.SECOND);
+
-
+
-
        2
+
-
        // initialize Timer with CalendarTime and 992ms delay from step to step
+
-
        (1000ms are too much, because the autotimer is delayed additionally)
+
-
        AutoTimer autoTimer = new AutoTimer(calendarTime, (long) 992);
+
-
+
-
        3
+
-
        // if it becomes more complicate it will be clearer to realize
+
-
        a subclass of TimerAdapter or to implement TimerListener
+
-
        autoTimer.addTimerListener(new TimerListener()
+
-
                {
+
-
                    public void onGoneAhead(TimerEvent timerEvent)
+
-
                    {
+
-
                        System.out.println(timerEvent.getTime());
+
-
                    }
+
-
 
+
-
                    public void onTimeSet(TimerEvent timerEvent)
+
-
                    {
+
-
 
+
-
                    }
+
-
 
+
-
                    public void onIntervalSet(TimerEvent timerEvent)
+
-
                    {
+
-
 
+
-
                    }
+
-
                });
+
-
        4
+
-
        // start the timer
+
-
        autoTimer.start();
+
-
</code>
+
-
 
+
-
====Select a time type====
+
-
 
+
-
'''Description:'''
+
-
A Time Object is used by the Timer. It gives the Timer it´s certain shape.
+
-
The Time Object defines which time field will be increased by goAhead method of the Timer.
+
-
Choose the following timer types:
+
-
 
+
-
* Date: "01.01.00" a simple date of the format: "dd.mm.yy".
+
-
* Step: "26" a Long value is used to represent the time.
+
-
* CalendarTime: "Sat Jul 20 15:38:53 CEST 2002" a time which is represented as a Gregorian Calendar.
+
-
