Constructor Detail

OldLayererWrapper

public OldLayererWrapper(Layerer oldLayerer)

Creates a new instance of OldLayererWrapper that wraps the given layerer instance.

Parameters:

oldLayerer - the old layerer implementation

Throws:

java.lang.IllegalArgumentException - if the given old layerer is null

Method Detail

assignLayers

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

Description copied from interface: Layerer

Assigns all nodes of the graph to layers and adds them to the Layers instance.

In order to create new layers, factory method Layers.insert(byte, int) has to be used.

Information about the nodes is provided by a LayoutDataProvider. However, positional information (see NodeData.getPosition() and NodeData.getLayer()) is not available during this phase.

Specified by:

assignLayers in interface Layerer

Parameters:

graph - the input graph

layers - the Layers instance that will be filled with the results of the calculation

ldp - the LayoutDataProvider used for querying information about the nodes and edges

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

getOldLayerer

public Layerer getOldLayerer()

Returns the delegate layerer instance.

Returns:

a layerer instance

setOldLayerer

public void setOldLayerer(Layerer oldLayerer)

Specifies the delegate layerer instance.

Parameters:

oldLayerer - the given layerer instance

Throws:

java.lang.IllegalArgumentException - if the specified Layerer is null
