| Class | public class LayoutMultiplexer |
| Inheritance | LayoutMultiplexer  AbstractLayoutStage YObject Object |
If a data provider is registered with the given graph using the look-up key LAYOUTER_DPKEY it is used to retrieve the com.yworks.yfiles.layout.Layouter objects that are stored for the graph's nodes. If no such data provider is registered, this layout stage's core layouter (if any) is used for layout calculation of all nodes. Note that the first non-null Layouter retrieved from the data provider is used for all nodes.
The main purpose of this class is to enable the use of individual layout algorithms for components (when used as the core layouter of class com.yworks.yfiles.layout.ComponentLayouter) or for the contents of group nodes (when used as the core layouter of class com.yworks.yfiles.layout.grouping.RecursiveGroupLayouter).
