5. Types of Objects of ADF BC contd…  Types of Objects of ADF Business Components (BC)  Business Domain Components  Entity Object (Data Persistence Business Object) Java PL/SQL  Association  Data Model Components  View Object (Data Query Business Object) Read only Updateable  View Link  Application Module Business Service Service Data Object

6. Types of VOs  Read Only VO (No Entity)  Static List (JDev demo)  SQL Query  Programmatic (Lesson 22)  Updatable VO (Single Entity)  Join VO (Multiple Entities)  Referenced Entity (JDev demo)  Updateable Entities (slides demo)  Master Detail VOs (Link)

7. Customizing EO’s Default Behavior Declaratively customize EO’s default behavior:  Customize attribute control hints (JDev):  Example: HireDate – Simple Date  Alternate key entity constraints  Synchronize columns with trigger-assigned values  Validate user input (Lesson 9 - Validation)

8. Customizing VO’s Default Behavior  Define attribute control hints: (Example: HireDate – Simple Date, AnnualSalary -- Width)  Perform calculations: Add transient attribute: (Example: AnnualSalary – 12*salary )  Projection: Restrict the columns retrieved by a query:  Example: select FIRST_NAME, LAST_NAME, EMAIL from employees ( EmpSqlQueryVO )  Sorting: reorder of queried rows using ORDER BY clause:  Example: select * from employees ORDER BY LAST_NAME ( EmpSqlQueryVO )  Selection: Restrict the rows retrieved by a query:  Where clause  Example: select * from EMPLOYEES WHERE email = ‘SKING’  Parameterized where clause with bind variable  Example: select * from employees WHERE email = :p_email ( EmployeeByEmailVO )  Structured/ Named where clause (View Criteria)  Parameterized structured/ named where clause (Example: p_email -- EmpSqlQueryVOCriteria )  Define a list of values (LOV): (Example: EmployeeSummaryVO-JobId -- JobVVO )

9. Customizing AM’s Default Behavior The Application Module editor has the following tabs:  General: Set tuning parameters and define custom properties  Data Model: Refine the data model  Java: Create Java classes and expose methods to the client interface  Web Service: Enable Web Service support  Configurations: Create or modify sets of configuration parameters

10. Categories & Subcategories of Validations in BC  Declarative Validation: Built-in Rules  Defined only at the entity level:  Collection validator  Unique key validator  Defined at the entity or attribute level, but pertain to an EO attribute:  Compare validator  Key Exists validator  Length validator  List validator  Range validator  Regular Expression validator  Defined at the entity or attribute level, to validate the EO or the attribute:  Script Expression validator  Declarative Validation: Custom Rules  Method validator  Programmatic Validation: Global Rules  Domains: Pre-validated Custom Datatypes

14. ADF Faces Functionality: ADF Faces Components  Layout Components: (L 12)  Headers, Layout, Grouping, Spacing, etc.  Navigation Control Components: (L14)  Button, Link, Train, Navigation, etc.  Menu and Toolbar explorer-type containers: (L 14)  Menu, Toolbar, Toolbox, etc.  Secondary Windows Layout: (L 14)  Popup, Dialog, Window, etc.  Text and Selection Components: (L18)  Output, Input, LOV, etc.  Data Views: (L 18)  Table, Tree, List, Carousel, Calendar, etc.  Advance Data Visualization Components (L 18)  Chart, Graph, Gauge, NBox, Pivot Table, Map, Gantt, Timeline, Hierarchy Viewer, Sunburst, Diagram, etc.  Data Query Components (L 19)  Query and Quick Query

15. ADF Faces Functionality: ADF Life Cycle Phases

16. Describing Types of Events  Action events  Occur when a command component is activated, such as when a user clicks a button or a link  Return a control flow outcome  Value change events  Occur when the local value of a input component changes, such as when a user selects a check box  Are used for managing UI elements  Phase events  Execute as part of the JSF and ADF life cycle  Can be used to augment standard behavior

17. Types of Event Listeners  ActionListener  Fired by submit buttons, image maps, and hypertext links with attached JavaScript   Automatically submit the form  ValueChangeListener  Fired by combo boxes, checkboxes, radio buttons, textfields, and others   Do not automatically submit the form

18. Phase Listener  Execute custom functions at a specific time during the request processing lifecycle  getPhaseId is called by the JSF framework to register the custom PhaseListener  PhaseListener is registered in faces-config.xml public class HRLifeCycleListener implements PhaseListener{ public PhaseId getPhaseId() { return PhaseId.ANY_PHASE; } public void beforePhase(PhaseEvent event) { System.out.println("START PHASE " + event.getPhaseId()); } public void afterPhase(PhaseEvent event) { System.out.println("END PHASE " + event.getPhaseId()); }
