class Var[T] extends Val[T] with StateChannel[T]

Var, as the name suggests, is very similar to a Scala var. The value is defined during instantiation, but may be modified later. The value may be a static value, or may be a derived value depending on multiple Observables. If Observables make up the value they will be monitored and events fired on this Observable as the value changes.

T

the type of value this channel receives

    Attaches a function to listen to values fired against this Observable.

    f

    function listener

    returns
