Class EdgeLayoutConstants

java.lang.Object
  extended bycom.tensegrity.graph.layout.edge.EdgeLayoutConstants
public class EdgeLayoutConstants
extends java.lang.Object

This class contains attributes and their default values that are used by class DefaultEdgeLayout.

Class DefaultEdgeLayout provides a path detector to route edges. It ensures that edges can be drawn without overlapping nodes by finding an appropriate path between them.
The following attributes can be used to enable the path detector and configure it:

In some cases the segments of different edges cover each other completely or in part so that it becomes difficult to distinguish between them. The DefaultEdgeLayout class provides a segment separator which is able to detect and shift these overlapping edge segments.

Forks can be used to bunch edge segments shortly before the node boundaries; By not using Forks, edges will run parallel up to node boundaries.

The following attributes help to configure the segment separator:

Building bridges at a crossing point between two edges helps to recognize the edge track better. The DefaultEdgeLayout class provides a bridge builder for this purpose.
There are several predefined bridge types and a bridge size that can be configured. The bridge builder merges several bridges into one if they are too close to each other. The edge distance attribute MIN_DISTANCE_TO_NODE_DESC has therefore a direct influence on this behavior. Please note that bridges will only be built if there is enough space to draw them completely.
The attributes listed below help to configure the bridges:

The bends of the orthogonal edges can be rounded. The DefaultEdgeLayout class uses quadrants to round the edge bends. The following attributes are provided to enable this feature and adjust the roundness of the bends:

The edge bends of simple orthogonal edges will normally be placed in the middle of the distance between the start and end points of the edges. This is usually not very convenient when the connected nodes are not perfectly aligned. This situation may occur when a user moves nodes around while modeling a graph.
The provided segment leveler may help to make the relationships clearer and the graph more orderly.

The DefaultEdgeLayout class arranges labels on the edges without changing the edge path. The labels will be arranged in such a way that they can be drawn without overlapping other labels or nodes. The position of the label will be changed only if it becomes absolutely necessary. The new position will always be on the appropriate edge.
The label arranger can be configured with following attributes:

The distance between the marker and the first and last bend of that marker can be set.
The following attributes can be used for this purpose:
