How to use findByKey() in ADF

Subject : 

   To find a specific row from a Row Set Iterator using findByKey() and setting the row as a current Row to a specific view object

Solution#1 - To get a specific row in Application Module Impl class


//Primary key value , Specify the data type accordingly
    String empID= "EMP001";
   
    // 1. Get the View Object instance
       EmployeeVO empVO = getEmployeeVO();
 
    // 2. Create a Key object
    Key key = new Key(new Object[] { empID });
   
    //3. Get the RowSetIterator Object
    RowSetIterator rsi = empVO.createRowSetIterator(null);
   
    //4. Find the row in the Iterator using findByKey funtion by passing Key object
    Row row = rsi.findByKey(key, 1)[0];
   
   // 6. Set the Current row in Iterator (findByKey does not Navigate to current row)
    rsi.setCurrentRow(row);


Solution#2 - To get a specific row in Managed Bean


//Primary key value , Specify the data type accordingly
    String empID= "EMP001";
   
    // 1. Access the binding container
    DCBindingContainer bc = (DCBindingContainer)getBindings();
 
   // 2. Find a named iterator binding
    DCIteratorBinding iter =
      (DCIteratorBinding)bc.findIteratorBinding("EmployeeVOIterator");
 
    // 3. Create a Key object
    Key key = new Key(new Object[] { empID});
   
    //4. Get the RowSetIterator Object
    RowSetIterator rsi = iter.getRowSetIterator();
   
    //5. Find the row in the Iterator using findByKey funtion by passing Key object
    Row row = rsi.findByKey(key, 1)[0];
   
   // 6. Set the Current row in Iterator (findByKey does not Navigate to current row)
    rsi.setCurrentRow(row);
