Difference between 'get' and 'observe'

[intellijel]

Just trying to figure out what the difference between "get" and "observe" is in the LOM?

I know that the former is for live.object and the latter for live.observer but don't they both return the same info?

get means you request the current value just once. just like a normal function call.

observe means that internally, an "observer" is installed which delivers the new value whenever it changes ("call back"). that's called notification within M4L. The only issue with observer calls is that you can't do any changes to the Live set based on a notification (unless you get a little bit creative).

I usually send the observer to the left inlet of a message box and then bang down the message, That seems to work pretty good.

haven't tried that yet, but I thought that if the bang originated from the observer as well (such as "trigger b float"), that would be prohibited by the Live API in order to avoid endless loops.
