3 -The layout data structure was generated with [[EMF>>url:http://www.eclipse.org/modeling/emf/||style="text-decoration: none;" shape="rect" class="ext-link"]] and is used in [[KIML>>doc:Infrastructure for Meta Layout (KIML)]] to attach layout options as well as layout information to each element of a [[KGraph>>doc:KGraph Meta Model]] structure. Layout options specify the behavior of layout algorithms for the specific graph instance, and layout information is written by layout algorithms to describe the position and size of each graph element. Many commonly used layout options are defined in the class [[LayoutOptions>>url:http://rtsys.informatik.uni-kiel.de/fisheye/browse/kieler/plugins/de.cau.cs.kieler.kiml/src/de/cau/cs/kieler/kiml/options/LayoutOptions.java||shape="rect"]], while each layout algorithm may additionally define its own specific options.

5 5  The KShapeLayout information is used for nodes, labels, and ports. It stores the position coordinates of the top left corner of the corresponding graph element as well as the size of its bounding box. Nodes may contain nested sub-graphs represented by their children reference; these child nodes are drawn inside the parent's bounding box respecting a certain border given by the KInsets object. The KEdgeLayout information is used for edges. It stores the position coordinates of the points where an edge touches its source node and its target node as well as the bend points.
