Class ViewAnimationFactory

java.lang.Object
  y.view.ViewAnimationFactory

public class ViewAnimationFactory
extends Object

Provides factory methods for miscellaneous animations.

• Moving of nodes
• Resizing of nodes
• Scaling of nodes
• Simple color transformations for nodes
• Blinking of nodes
• Several animated effects related to node and edge creation and deletion:
  • Fading in and out
  • Blurring in and out
  • Implosion and Explosion
  • Whirling in and out (nodes only)
  • Extracting and Retracting (edges only)
• Fading in and out for whole graph structures
• Similar effects for Drawables

Animations created through the factory methods of this class require either the associated Graph2DView or the associated Graph2DViewRepaintManager to be registered as an AnimationListener with the AnimationPlayer used to process the animations.
For this reason, a convenience factory method createConfiguredPlayer is provided that ensures that a suitable AnimationListener is registered on the returned AnimationPlayer.

This class also provides factory methods to create Drawable representations of NodeRealizer, EdgeRealizer, and YLabel instances.

                               double ratio,
                               long preferredDuration)

Creates an AnimationObject that applies a fade-out effect to the specified Graph2D by successively fading out nodes and retracting edges.

Throws:

IllegalArgumentException - if preferredDuration is less than 0.

Parameters:

graph - the Graph to which the fade effect is applied.

order - specifies an ordering of the nodes in graph that determines the chronological order of the fade-out effects for the nodes.

obeyEdgeDirection - if true, edge retraction is done from edge source to edge target; otherwise edge retraction is done according to the given NodeOrder.

ratio - specifies the ratio of the preferred duration for the fade effects of the individual graph objects to the total preferred duration given by preferredDuration.

preferredDuration - the preferred animation duration measured in milliseconds.

Returns:

an AnimationObject that applies a fade from visibility to invisibility effect to graph.

Postcondition:

After the animation is done, the visible property of all realizers in graph will be false.

createDrawable

public static Drawable createDrawable(NodeRealizer nr)

Creates a Drawable representation of the specified NodeRealizer that is independent of the graph to which the realizer's node belongs.

Parameters:

nr - the NodeRealizer

Returns:

a Drawable representation of nr.

createDrawable

public static Drawable createDrawable(EdgeRealizer er)

Creates a Drawable representation of the specified EdgeRealizer that is independent of the graph to which the realizer's edge belongs.

This implementation works properly for simple edge paths only.

Parameters:

er - the EdgeRealizer

Returns:

a Drawable representation of er.

createDrawable

public static Drawable createDrawable(YLabel label)

Creates a Drawable representation of the specified YLabel.

Parameters:

label - the YLabel

Returns:

a Drawable representation of label.

createConfiguredPlayer

public AnimationPlayer createConfiguredPlayer()

Creates a new AnimationPlayer that is set to be non-blocking and on which an AnimationListener, which ensures that this factory's Graph2DView gets updated on animation events, has been registered.

Returns:

a non-blocking AnimationPlayer

focusView

public AnimationObject focusView(double newZoom,
                                 Value2D newCenter,
                                 long preferredDuration)

Creates an AnimationObject that smoothly changes the zoom level and center view point of this factory's Graph2DView.

Throws:

IllegalArgumentException - if preferredDuration is less than 0.

Parameters:

newZoom - the new zoom level

newCenter - the new center coordinate of the view.

preferredDuration - the preferred animation duration measured in milliseconds.

Returns:

an AnimationObject that that smoothly changes the zoom level and center view point of this factory's Graph2DView.
