The Eclipse Layout Kernel (ELK) is the official Eclipse project our layout technology will move to. As part of the move, expect changes in these areas:

• Plugin names
• Extension point names
• Package names
• Plugin structure
• KGraph meta model

To make migration easier for everyone, this page is intended to track all changes.

• The classes formerly provided by de.cau.cs.kieler.core are now to be found in org.eclipse.elk.core, with the following exceptions:
  • The ...properties package was moved to the .graph plugin.
  • ForwardingInputStream was moved to the ...graphviz.layouter plugin.
  • ForkedOutputStream was moved to the ...graphviz.layouter plugin.
• All pre-defined layout types now have the ID org.eclipse.elk.type.XXX
• All pre-defined diagram types now have the ID org.eclipse.elk.diagram.XXX
• All pre-defined layout options now have the ID org.eclipse.elk.XXX (except for options defined by specific layout algorithms, which have the ID org.eclipse.elk.ALGORITHM.XXX)
  • de.cau.cs.kieler.klay.layered.portAnchor is now org.eclipse.elk.portAnchor instead of org.eclipse.elk.layered.portAnchor
• All pre-defined layout algorithms now have the ID org.eclipse.elk.algorithm.XXX

• IKielerProgressMonitor -> IElkProgressMonitor

• ILayoutConfig -> LayoutConfigurator

• IVolatileLayoutConfig

  • use LayoutConfigurator

  • to set global options

    IVolatileLayoutConfig#setValue(prop, value) --> LayoutConfigurator#configure(KGraphElement.class).setProperty(prop, value)

• IDiagramLayoutManager -> IDiagramLayoutConnector

• LayoutManagerService -> LayoutConnectorsService

• LayoutListeners:

  DiagramLayoutEngine.INSTANCE.addLayoutTerminatedListener(new DiagramLayoutEngine.ILayoutTerminatedListener() { --> LayoutConnectorsService.getInstance().addLayoutListener(new ILayoutListener() {

• KimlUtil.loadDataElements(...) -> GraphDataUtil.loadDataElements(...)

Perhaps of lesser interest:

• We now depend on Google Guava 15 instead of 10.
