Make MarkupContainer streamable?

[Martijn Dashorst]

In our code I often see code that (ugh) retrieves a component by id,
something like:

public class SomePanel extends Panel {
    ...
       target.add(getPage().get("feedback"));
    ...
}

If we made MarkupContainer streamable, we could, in pseudo code, do
something like:

getPage().stream().filter(c->c.getId().equals("feedback")).findFirst();

Which is not better than getPage().get("feedback")

But it is more flexible checking for types, etc.

The implementation is not that complicated:


/**
 * Returns a sequential {@code Stream} with the children of this
markup container
 *  as its source.
 *
 * @return a sequential {@code Stream} over the children of this
markup container
 * @since 8.0
 */
public Stream<Component> stream()
{
    return StreamSupport.stream(spliterator(), false);
}

Good idea?
