Would you mind to provide an example of the use of flatMap?.

I need to adapt old b56 code like this:

Set<Polyline> lines(mapName){};
namesColl.flatMap(name -> lines(name)).into(...);

to the new sintax but I have no idea how to start with (do I have to provide
a Block.instance?)

I made some web search on flatMap and jdk8 but everyone seems to be talking
about Optional. 
And in the repos I couln't find a single example, only discussions about the
sintax.
