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

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
