Manipule a lista in data control

Question

Hi everyone,
I have a data control from a oracle component and I don't have access to this code, so I used it in my page, the data control returns a collection of items, so I can use adf tree and other thinks like that.
The data control is a data control from a UCM component and I'm using getItems method.
So, as I say before I don't have access to the code of data control but I need manipulate the return with java operations, I need sort this list.
I was thinking about call this method in my java method and create my custom data control, but I don't know how "call" the data control method in my custom method.
I would like to know if it's possible cat the result of this oracle data control in a java method and so I can manipulate this.
Thks in advance,

Answer 1

Is it possible to which type of Object, the list returned by the datacontrol contains?
If yes, you could create a custom comparator,
(The below sample NavigationTreeNode is the type of each item in the list)
import java.util.Comparator;
public class NavigationTreeNodeComparator implements Comparator<NavigationTreeNode> {
public NavigationTreeNodeComparator() {
super();
@Override
public int compare(NavigationTreeNode navigationTreeNode1,
NavigationTreeNode navigationTreeNode2) {
int displaySequence1 = navigationTreeNode1.getDisplaySequence();
int displaySequence2 = navigationTreeNode2.getDisplaySequence();
if (displaySequence1 > displaySequence2) {
return +1;
} else if (displaySequence1 < displaySequence2) {
return -1;
} else {
return 0;
After getting the list from method, you can use the custom comparator to sort the list as follows:
Here, the navigationTree contains the list of navigationTreeNodes
NavigationTreeNodeComparator navigationTreeNodeComparator =
new NavigationTreeNodeComparator();
Collections.sort(navigationTree, navigationTreeNodeComparator);
