ADF : View Criteria complex code snippets

View Criteria is a declarative representation of View Object where clause. View Criteria contain a criteria row that itself contains attributes/items that the where clause constructs.


vo = this.getEmpVO();

//To get all the view criterias currently applied on a VO

String[] criterias =  vo.getViewCriteriaManager().getApplyViewCriteriaNames();


//To see all the applied view criterias on a VO

        String[] criterias =  vo.getViewCriteriaManager().getApplyViewCriteriaNames();
        if (Tcriterias != null) {
            for (String vcName : criterias) {
                System.out.println("ViewCriteria :" + vcName);
            }
        }


//To unapply a view criterias on a VO which is currently applied.

String[] criterias =  vo.getViewCriteriaManager().getApplyViewCriteriaNames();
        if (Tcriterias != null) {
            for (String vcName : criterias) {
               vo.getViewCriteriaManager().removeApplyViewCriteriaName(vcName);
            }
        }


//To see all the view criteria items inside a view criteria row

List list = vc.getRows(); //(vc is a view criteria)

Iterator iter1 = list.iterator();
while (iter1.hasNext()) {
      

                   ViewCriteriaRow row = (ViewCriteriaRow)iter1.next();

                   row.getCriteriaItem("EmpId");
                   row.getCriteriaItem("EmpName").getValue();

                   List vcitems = row.getCriteriaItems();
                  Iterator itemiter = vcitems.iterator();

                 while (itemiter.hasNext()) {
                             
                   ViewCriteriaItem vcitem = (ViewCriteriaItem)itemiter.next();
                   System.out.println("vcitemname in vcrow:"+vcitem.getName());
                   System.out.println("vcitemvalue in vcrow:"+vcitem.getValue());
                  
         }

}

//Add the row to the existing Criteria
vc.addElement(criteriaRow);
