[OmniFaces utilities 2.0] Convert an iterable into a list


[OmniFaces utilities] The iterableToList() method converts an iterable into a list. This method makes NO guarantee to whether changes to the source iterable are reflected in the returned list or not. For instance if the given iterable already is a list, it's returned directly.

Method:
Usage:

For example, OmniFaces uses this utility in its custom DataModel named, IterableDataModel. In order to override the setWrappedData() method:

import static org.omnifaces.util.Utils.iterableToList;
...
private Iterable<E> iterable;
private List<E> list;
...
@Override
public void setWrappedData(Object data) {
 if (data == null) {
     iterable = null;
     list = null;
     setRowIndex(-1);
 } else {
     iterable = (Iterable<E>) data;
     list = iterableToList(iterable);
     setRowIndex(0);
 }
}
