| BasicLineGraphGenerator | | public class BasicLineGraphGenerator implements LineGraphGenerator(Code) | | An implementation of GraphGenerator used to generate a graph representing a
line network. Graphs are generated by supplying the generator with objects
of type LineSegment via the add(Object) method.
For each line segment added, an edge in the graph is created. The builder
records the end coordinates of each line added, and maintains a map of
coordinates to nodes, creating nodes when neccessary.
Edges created by the generator are of type BasicEdge and contain an object
of type LineSegment.
Nodes created by the generator are of type BasicXYNode and contain an object
of type Coordinate.

| get | | public Graphable get(Object obj)(Code) | | Returns the edge which represents a line. Note that if the exact same line
has been added to the graph multiple times, then only one of the edges that
represents it will be returned. It is undefined which edge will be returned.
Parameters:
obj - An instance of LineSegment. Edge that represents the line.

endpoint coordinates.
