Registers a live observer with this observable.
Registers a live observer with this observable. The method is called with the
observing function which receives the observable's update message of type A
, and the
method generates an opaque Disposable
instance, which may be used to
remove the observer eventually (through the dispose
method).
An
AuralAttribute.Target
describes the mechanism by which the attribute inputs can contribute their values. It is internally connected to the process's node. One or multiple inputs then supply their values by callingput
and detach themselves by callingremove
. The target automatically manages summing multiple inputs. While theValue
parameter forput
corresponds to a particular attribute input, itsvalueOption
gives the overall signal output as sent to the node. For instance, a stream input will have a bus to which is writes, whereas the target itself may provide a bus from this node reads.
