[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);

 }

}
