### DefaultMomentum

    public DefaultMomentum()

Method Detail

### createState

    public Momentum.State createState(Point initialPosition,
                                      Point initialVelocity)

  Description copied from interface: `Momentum`
  Create a `Momentum.State` instance. The `Momentum.State` instance will be passed to `Momentum.updateState(State)` until the momentum is depleted.

  Specified by:
    `createState` in interface `Momentum`
  Parameters:
    `initialPosition` - the initial position
    `initialVelocity` - the initial velocity in pixels per millisecond

### updateState

    public boolean updateState(Momentum.State state)

  Description copied from interface: `Momentum`

  Update the state based on the specified `Momentum.State`. When no more momentum remains, this method should return false to stop future calls.

  The `Momentum.State` instance is created by a call to `Momentum.createState(Point, Point)`, and the same instance if used for the duration of the momentum. This method should modify the existing state by calling `Momentum.State.setPosition(Point)` and/or `Momentum.State.setVelocity(Point)`.

  Specified by:
    `updateState` in interface `Momentum`
  Parameters:
    `state` - the current state
  Returns:
    true to continue momentum, false if no momentum remains
