  Returns:
    the attractor

### getJitter

    public float getJitter()

  Returns:
    the jitter

### getRadius

    public float getRadius()

  Returns:
    the radius

### getStrength

    public float getStrength()

  Returns:
    the strength

### setAttractor

    public void setAttractor(toxi.geom.Vec2D attractor)

  Parameters:
    `attractor` - the attractor to set

### setJitter

    public void setJitter(float jitter)

  Parameters:
    `jitter` - the jitter to set

### setStrength

    public void setStrength(float strength)
