java.lang.Object y.layout.EdgeBundleDescriptor
public class EdgeBundleDescriptor
An EdgeBundleDescriptor
defines the bundling
settings of an edge.
The defined settings will be considered by layout algorithms
which support edge bundling.
Each EdgeBundleDescriptor
can either be specified for a single edge or shared by several edges.
It is assigned to an edge by registering a DataProvider
with key
EdgeBundling.EDGE_BUNDLE_DESCRIPTOR_DPKEY
to the input graph.

Constructor Summary  

EdgeBundleDescriptor()
Creates a new EdgeBundleDescriptor with default settings. 

EdgeBundleDescriptor(EdgeBundleDescriptor descriptor)
Creates a new EdgeBundleDescriptor representing a copy of the given other descriptor instance.

public boolean isDirectionConsiderationEnabled()
During the bundling procedure, the edges are bundled based on their direction such that the incoming edges of a node are bundled separately from its outgoing edges. If the direction of edges adjacent to a node is not considered, then they are not bundled separately.
If the direction of some edges is taken into consideration while the direction of some others (adjacent to the same node) is ignored, the undirected edges are also bundled separately. This is done to distinguish them from the incoming and outgoing edges of the particular node.

If disabled, the edges resemble Bsplines where points of the path are actually curve points. Therefore, this representation requires a high number of bends to model curves.
If this feature is enabled, a bezier curve is fitted to the start and end point as well as the intermediate control points of the edge. After the fitting, the points of the edge can be interpreted as cubic bezier control points. Each four consecutive points form a bezier curve, where the first and last of the four points represent the start and end of the curve and the second and third point are the control points defining how the curve looks. The second and third point do not necessarily lie on the actual curve.
