Description

Interface Summary

EllipticalGroupBoundsCalculator.ShapePointProvider	A ShapePointProvider retrieves the points that lie on the convex hull (the shape points) of the visual shape of the nodes in the graph.
InteractiveOrganicLayouter.SingleThreadContext	A InteractiveOrganicLayouter.SingleThreadContext provides control over the layout calculation in the case of single-threaded algorithm execution.

Class Summary

EllipticalGroupBoundsCalculator	EllipticalGroupBoundsCalculator is a GroupBoundsCalculator implementation which assumes that group nodes have an elliptical shape.
EllipticalGroupBoundsCalculator.EllipticalShapePointProvider	This is a default implementation of EllipticalGroupBoundsCalculator.ShapePointProvider that assumes elliptical node shapes.
GRIP	This layout algorithm arranges graphs in an organic fashion.
GroupedShuffleLayouter	This algorithm recursively removes node overlaps from a graph with a hierarchic group structure.
InteractiveOrganicLayouter	This algorithm arranges graphs in an organic fashion and offers special functionality to interact with the graph while the algorithm is running.
OrganicLayouter	A layout algorithm that arranges graphs in an organic fashion, using a force-directed drawing approach.
OrganicPartitionGridLayoutStage	This layout stage enables support for handling a graph with a PartitionGrid structure.
OrganicRemoveOverlapsStage	This layout stage removes node overlaps while changes to the original layout structure are avoided and a specified minimum node distance is guaranteed.
OutputRestriction	OutputRestrictions restrict the output area and the shape of a layout in conjunction with organic layout algorithms such as SmartOrganicLayouter or InteractiveOrganicLayouter.
RemoveOverlapsLayoutStage	This LayoutStage removes node overlaps and guarantees a certain minimum distance between nodes.
ShuffleLayouter	This layout algorithm removes overlaps between nodes in a graph.
SmartOrganicLayouter	This layout algorithm arranges graphs in an organic fashion.
SplitEdgeLayoutStage	This layout stage replaces edges by a path of split-edges with a specified length before it calls a core layout algorithm.

Package y.layout.organic Description

Provides organic layout style algorithms that are based on a force-directed layout paradigm.

Organic layouts distribute nodes in a natural way and are well suited to exhibit clusters and symmetric properties of a graph.

SmartOrganicLayouter, the main implementation for the organic layout style, supports both complete re-layout of a given diagram as well as incremental layout where only a subset of a diagram should be rearranged.
Also, SmartOrganicLayouter supports layout of "flat" as well as grouped graphs, i.e., graphs where nodes are contained within other so-called group nodes.

InteractiveOrganicLayouter provides support for interactive layouts, enabling live interactions with an adapting organic graph layout.

Note that OrganicLayouter is a legacy layout algorithm for the organic layout style. It is superseded by SmartOrganicLayouter, which adds features to prevent node (label) overlaps and to keep minimum distances between the nodes.
