oldLayerer - the old layerer implementation

Method Detail

assignLayers

public void assignLayers(LayoutGraph graph,
                         Layers layers,
                         LayoutDataProvider ldp)

Description copied from interface: Layerer

This method assigns all nodes in the graph to layers and registers them in the Layers instance. In order to create new layers, the factory method Layers.insert(byte, int) must be used.

Specified by:

assignLayers in interface Layerer

Parameters:

graph - the graph that contains the nodes that should be distributed into the layers

layers - the object that will be filled with the results of the calculation

ldp - LayoutDataProvider that can be used to query information about the nodes - note that positional information (see NodeData.getPosition() and NodeData.getLayer()) cannot be available at any time.

Layers.insert(byte, int), Layer.add(y.base.Node)

getOldLayerer

public Layerer getOldLayerer()

Returns the y.layout.hierarchic.Layerer instance that is used for delegation.

Returns:

the delegate instance

setOldLayerer

public void setOldLayerer(Layerer oldLayerer)

Sets the new delegate Layerer instance.

Throws:

NullPointerException - if the argument is null

Parameters:

oldLayerer - the new instance.
