    Create a dependent Var which behaves as f applied to the current value of this Var.

    Create a dependent Var which behaves as f applied to the current value of this Var. FlatMap manages a dynamic dependency graph: the dependent Var is detached and recomputed whenever the outer Var changes, but only if there are any observers. An unobserved Var returned by flatMap will not invoke f

  21. def observe(depth: Int, obs: Observer[T]): Closable

    Concrete implementations of Var implement observe.

    Concrete implementations of Var implement observe. This is called for each toplevel observe. Depths indicate the relative structural depth of the observation, from the frame of reference of the root call to observe. (Each Var derived via flatMap increases the depth.) Depths are used to order the invocation of update callbacks. This is used to ensure that updates proceed in topological order so that every input variable is fully resolved before recomputing a derived variable.

  4. def observeUntil(pred: (T) ⇒ Boolean): Future[T]

    A one-shot predicate observation.

    A one-shot predicate observation. The returned future is satisfied with the first observed value of Var that obtains the predicate pred. Observation stops when the future is satisfied.

    Interrupting the future will also satisfy the future (with the interrupt exception) and close the observation.
