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.

Method Detail

interpolateback to summary
protected void interpolate(double frac)

Implements abstract javafx.animation.Transition.interpolate.

Doc from javafx.animation.Transition.interpolate.

The method interpolate() has to be provided by implementations of Transition. While a Transition is running, this method is called in every frame. The parameter defines the current position with the animation. At the start, the fraction will be 0.0 and at the end it will be 1.0. How the parameter increases, depends on the interpolator, e.g. if the interpolator is Interpolator#LINEAR, the fraction will increase linear. This method must not be called by the user directly.
