Application Class

Steps to create application Class:
1. Create an application package.
2. Create an application class.
3. Code your class.
4. Test your code.

Using Application designer we can do step-1 and Step-2 above.

Step-3 might look something like this:

class MyClass
   method GreetMe() Returns string;
end-class;

method GreetMe
    Return "Hello " | %OperatorId;
end-method;

Step-4 Test the code:

import GREETERS:MyClass;
Local GREETERS:MyClass &greeter = create GREETERS:MyClass();
Local string &message = &greeter.GreetMe();
MessageBox(0, "", 0, 0, &message);


The first line of this listing imports the MyClass application class into the current PeopleCode module in a manner similar
to a PeopleCode Declare directive.
The second line creates a new instance of the MyClass class using the create keyword.

Inappropriate use of application Class:
1) Avoid using Runtime Context-Sensitive Variables such as %Component, %Portal, %Request, %Page, %Response.

2) Avoid Event-Based PeopleCode such as SavePostChange for Application Classes.
