All Implemented Interfaces:

GeometryFactory

public class IndexedLineSetFactory
extends AbstractIndexedLineSetFactory

This is a factory class for constructing and editing instances of IndexedLineSet. For an introduction to the way these geometry factories work, see the documentation for the superclass PointSetFactory.

In addition to the functionality inherited from PointSetFactory, this class offers methods to set and edit the edge information of an IndexedLineSet. (Here edge is synonymous with 'line'.) This is first and foremost an array of type int[][] which specifies the combinatorics: which vertices are connected by edges. First call setEdgeCount(int) to set the number of edges, then use the method setEdgeIndices(int[][]) and its variants to set this information.

There are also methods for setting the builtin attributes colors and labels. For other attributes, use the methods: * For attributes not included in the built-in set, use the methods

• setEdgeAttribute(Attribute, DataList)
• setEdgeAttribute(Attribute, double[])
• setEdgeAttribute(Attribute, double[][])

You can also request the factory to automatically generate edge labels (which are strings displayed as 3D text at the midpoint of the edges) using the method AbstractIndexedLineSetFactory.setGenerateEdgeLabels(boolean). This will generate labels showing the index of the edge within the edge array. (Probably only works correctly when all edges consist of two points).

For an example, see this tutorial.
