arrow.isStartDummy() tells you whether the start of the arrow is
connected to an element.
arrow.isEndDummy() is an analogy for the end of the arrow.
Hence: arrow.isStartDummy() && arrow.isEndDummy() is true if the arrow
is not connected to any element.

Just as a side note, dummy is an invisible object that is created if a
side of an arrow gets disconnected from an element.
It can even be styled in the Joint options object:
opt.dummy.start.radius, opt.dummy.start.attrs (replace 'start' with
'end' for the arrow end dummy).

Cheers,
David
