Iterating ViewObject vertically (get all attributes of ViewObject) programmatically

Hello All,
This post talks about a requirement of getting all attributes (column names) of a viewObject programmatically

  • Create a fusion web application and business component using department table

  • you can see all attributes in  Departments entity object

  • Now to get ViewObject's attributes name , there is a method written in AMImpl class , see it, i have added a facesMessage to show all names on a Message Board



  •     /**Method to get all attributes of a viewObject
         * */
        public void iterateVoVertically() {
            ViewObjectImpl vo = this.getDepartments1();
            ViewAttributeDefImpl[] attrDefs = vo.getViewAttributeDefImpls();
            int count = 0;
            StringBuilder infoMsg =
                new StringBuilder("<html><body><b><p style='color:red'> Attribute of Department ViewObject are-</p></b>");
            infoMsg.append("<ul>");
    
    
            for (ViewAttributeDefImpl attrDef : attrDefs) {
                byte attrKind =
                    attrDefs[count].getAttributeKind(); //checks attribute kind for each element in an array of AttributeDefs
                if (attrKind != AttributeDef.ATTR_ASSOCIATED_ROW && attrKind != AttributeDef.ATTR_ASSOCIATED_ROWITERATOR) {
                    String columnName = attrDef.getName();
                    infoMsg.append("<li> <b>" + attrDef.getName() + "</b></li>");
                    System.out.println("Column Name-" + columnName);
                }
            }
            infoMsg.append("</ul><br>");
            infoMsg.append("</body></html>");
            FacesMessage msg = new FacesMessage(infoMsg.toString());
            msg.setSeverity(FacesMessage.SEVERITY_INFO);
            FacesContext.getCurrentInstance().addMessage(null, msg);
        }
    

  • I have called this method through page binding and AM Client on a button of page

  • now on click of button all attributes of Departments ViewObject are shown in FacesMessage, you can use it in your code
 Cheers :-)
