- Method Detail
  - setItems
```
void setItems(Collection<T> items)
```
    Sets the data items of this component provided as a collection.
    The provided collection instance may be used as-is. Subsequent modification of the collection might cause inconsistent data to be shown in the component unless it is explicitly instructed to read the data again.
    
    Parameters:
    
    items - the data items to display, not null
  - setItems
```
default void setItems(T... items)
```
    Sets the data items of this listing.
    
    Parameters:
    
    items - the data items to display, the array must not be null
    
    See Also:
    
    setItems(Collection)
  - setItems
```
default void setItems(Stream<T> streamOfItems)
```
    Sets the data items of this listing provided as a stream.
    This is just a shorthand for setItems(Collection), that collects objects in the stream to a list. Thus, using this method, instead of its array and Collection variations, doesn't save any memory.
    
    Parameters:
    
    streamOfItems - the stream of data items to display, not null

    setItems(Collection)
