connect	back to summary
protected Subscription connect() Implements abstract org.reactfx.value.ValBase.connect. Doc from org.reactfx.value.ValBase.connect. 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 call `invalidate()` to notify observers of this Val. By the time of calling invalidate(), the input observer must have already updated any internal state of this Val, so that a subsequent call to `computeValue()` returns the current value of this Val.
