Method Detail

connect
protected Subscription connect()
Description copied from class:ValBase
Implementation of this method should start observing inputs. If the value of this Val may change as a result of input change, the corresponding input observer should callValBase.invalidate()
to notify observers of this Val. By the time of calling ValBase.invalidate(), the input observer must have already updated any internal state of this Val, so that a subsequent call toValBase.computeValue()
returns the current value of this Val.
