Class IlvAnimationRenderer

java.lang.Object

ilog.views.sdm.renderer.IlvSDMRenderer

ilog.views.sdm.renderer.IlvFilterSDMRenderer

ilog.views.sdm.renderer.animation.IlvAnimationRenderer

All Implemented Interfaces:

Serializable

public class IlvAnimationRenderer
extends IlvFilterSDMRenderer

The class IlvAnimationRenderer is a filtering renderer that displays an animation showing how the nodes of the graph have moved during the last rendering step.

The animation is especially useful when you use an IlvGraphLayoutRenderer. The animation will show how the nodes have been placed by the graph layout algorithm.

Since:

JViews 4.0

Constructor Detail

IlvAnimationRenderer

public IlvAnimationRenderer(IlvSDMRenderer renderer)

Creates a new animation renderer for a specified filtered renderer.

Parameters:

renderer - The filtered renderer.

IlvAnimationRenderer

public IlvAnimationRenderer()

Creates a new animation renderer with a null filtered renderer.

Method Detail

setAnimationRate

public void setAnimationRate(int rate)

Sets the number of animation steps.

Parameters:

rate - The new animation rate.

getAnimationRate

public int getAnimationRate()

Returns the number of animation steps.

setAnimationAccelerationRate

public void setAnimationAccelerationRate(int rate)

Sets the number of animation accelerating and decelerating steps. The effective animation acceleration rate cannot be larger than half the animation rate. If it is exactly half the animation rate, the animated objects accelerate during the first half of the animation and decelerate during the second half of the animation. If the animation rate is larger than twice the acceleration rate, the animated objects move with constant speed after the acceleration phase and before the deceleration phase.

Parameters:

rate - The new acceleration rate.

Since:

JViews 8.6

getAnimationAccelerationRate

public int getAnimationAccelerationRate()

Returns the number of animation accelerating and deaccelerating steps.

Since:

JViews 8.6

setAnimationDelay

public void setAnimationDelay(int delay)

Sets the delay between two steps of the animation.

Parameters:

delay - The new animation delay.

getAnimationDelay

public int getAnimationDelay()

Returns the delay between two steps of the animation.

isResizingObjects

public boolean isResizingObjects()

Returns true if the animator resizes the objects.

See Also:

setResizingObjects(boolean)

setResizingObjects

public void setResizingObjects(boolean resizing)

If resizing is true, the width and height of the graphic objects are changed linearly from the initial size to the final size. If resizing is false, the objects are only moved, and not resized.

The default value is true.

Parameters:

resizing - The Boolean value that determines whether the objects must be resized or not.

renderingDone

public void renderingDone(IlvSDMEngine engine)

This method performs the animation. It first takes a snapshot of the object positions, then calls its superclass (which calls the renderingDone method of the other filtered renderers), and finally displays an animation showing how the objects have moved.

Overrides:

renderingDone in class IlvFilterSDMRenderer

Parameters:

engine - The SDM engine.
