The end() means to close the block, just like the "}" in java, it is
very useful for the choice() fluent API.

Thanks. I'll try that. The multicast fluent builder example
http://activemq.apache.org/camel/multicast.html here doesn't use end:
from("direct:a").multicast().to("direct:x", "direct:y", "direct:z");
What's the difference between:
multicast().to("direct:x", "direct:y", "direct:z").end();
and
to("direct:x", "direct:y", "direct:z");
Thanks.

Hi,
Did you try end() to terminate the multicast? As in:
from(uri).
choice().
when(expr).multicast().to(uris).end().
otherwise().to(pojo);
Cheers

I'm trying to broadcast a feed to multiple endpoints but with
content-based selection. I assume I need to use multicast, however, I
can't achieve conditional multicast based on content selection
since I
can't use an otherwise() method after using
multicast().to("endpoint1",
"endpoint2")
Furthermore, the to() method supports a list of endpoints without
requiring a multicast first so what is the difference between that
and a
multicast().to(...)?
feed in -> multicast to two outputs
To recap with code:
1) I can't use otherwise after a multicast...
from(cnn).
choice().
when(xpath(filter)).multicast().to(im, archive); // I
can't now use otherwise()...
2) Do I really need multicast or can I just do the following...?
from(cnn).
choice().
when(xpath(filter)).to(im, archive).
otherwise().to(myPojo);
One way I've worked around this is to inverse the filter and do the
multicast in the otherwise() part but clearly this doesn't answer my
original question:
from(cnn).
choice().
when(xpath(filter)).to(stdout).
otherwise().multicast().to(im, archive);
