Val

Val, as the name suggests, is like a Scala val. This represents an immutable value that is set in the first place and then not modified. However, since the value set may be built from Observables, the generated value may change over time as its dependencies are modified. This class is Observable and will only fire changes if the underlying value is derived from one or more Observables.

Called when assigning the value.
Called when assigning the value. This method removes any existing monitored Observables, determines the new Observables from the supplied function f, and monitors changes to any of those.
