129 129  Diagram types are used to classify graphical diagrams for setting default layout option values for a set of similar diagrams. The diagram type of an element is specified with the layout option {{code language="none"}}de.cau.cs.kieler.diagramType{{/code}}. Layout algorithms can declare which diagram types they support well, and give a priority value for each supported type. KIML decides at runtime which layout algorithm has the highest priority for a given diagram, so that the most suitable algorithm is always used. Usual values for such priorities are between 1 and 10, where the highest value should only be assigned if the algorithm is especially designed for diagrams of the respective type, or if it has proven to be very adequate for them. Lower values should be given if the algorithm is able to draw the diagrams correctly, but with lower quality of the resulting layout.

188 +The transformation of input diagrams to [[KGraph>>doc:KGraph Meta Model]] instances as well as the transfer of computed layouts back to the input diagrams is done by [[IDiagramLayoutManager>>url:http://rtsys.informatik.uni-kiel.de/fisheye/browse/kieler/plugins/de.cau.cs.kieler.kiml.ui/src/de/cau/cs/kieler/kiml/ui/diagram/IDiagramLayoutManager.java||shape="rect"]] implementations. For most diagram editors that are based on [[GMF>>url:http://www.eclipse.org/modeling/gmp/||shape="rect"]] the generic [[GmfDiagramLayoutManager>>url:http://rtsys.informatik.uni-kiel.de/fisheye/browse/kieler/plugins/de.cau.cs.kieler.kiml.gmf/src/de/cau/cs/kieler/kiml/gmf/GmfDiagramLayoutManager.java||shape="rect"]] can be used, while for [[Graphiti>>url:http://www.eclipse.org/graphiti/||shape="rect"]] there is the generic [[GraphitiDiagramLayoutManager>>url:http://rtsys.informatik.uni-kiel.de/fisheye/browse/kieler/plugins/de.cau.cs.kieler.kiml.graphiti/src/de/cau/cs/kieler/kiml/graphiti/GraphitiDiagramLayoutManager.java||shape="rect"]]. However, some customized diagram editors do not work with the generic diagram layout managers and hence require their own specialized implementations, which can be contributed with the extension point layoutManagers{{code language="none"}}{{/code}}.

192 -KIML offers an interface for graph analysis, available with the [[image:attach:KIELER.Infrastructure for Meta Layout (KIML)@analyzediagram.gif]] button. Here a selection of analyses can be made, which refer to the structure or to the drawing of the graph. After performing the analyses, the results are shown in a dialog and in the Analysis view. New analyses, which must implement [[IAnalysis>>url:http://rtsys.informatik.uni-kiel.de/fisheye/browse/kieler/plugins/de.cau.cs.kieler.kiml.service/src/de/cau/cs/kieler/kiml/service/grana/IAnalysis.java||shape="rect"]], can be registered using the {{code language="none"}}analysisProviders{{/code}} extension point.
