Constructor Detail

AngleAnimator

public AngleAnimator(Interpolator interpolator,
                     Angle begin,
                     Angle end,
                     PropertyAccessor.AngleAccessor propertyAccessor)

Construct an AngleAnimator

Parameters:

interpolator - the Interpolator

begin - angle the animation begins at

end - The angle the animation ends at.

propertyAccessor - The PropertyAccessor used to modify the data value being animated.

Method Detail

getBegin

public Angle getBegin()

Get the current begin value.

Returns:

the current begin value.

getEnd

public Angle getEnd()

Get the current end value.

Returns:

the current end value.

getPropertyAccessor

public PropertyAccessor.AngleAccessor getPropertyAccessor()

Get the PropertyAccessor in use by this animation

Returns:

the PropertyAccessor in use by this animation

setBegin

public void setBegin(Angle begin)

Set the begin value.

Parameters:

begin - the new begin value.

setEnd

public void setEnd(Angle end)

Set the end value.

Parameters:

end - the new end value.

setImpl

protected void setImpl(double interpolant)

Set the value being animated via the PropertyAccessor using the passed interpolant. This implementation just does a straight liner interpolation between the begin and end values.

Overrides:

setImpl in class BasicAnimator

Parameters:

interpolant - the interpolant used to generate the next value that will be set by the PropertyAccessor
