use the source, (and the examples/testcases) in the source you'll see that the .end checks if end is not null. surprisingly, setEnd sets end so.....oh and in the api you'll also see that there is an .end(transition) so...... look at the examples........ btw, it's so simple to use the source, much simpler and takes lots less time than typing this message.
