Method Summary

E	getEdge(Layout<V,E> layout, double x, double y) Returns an edge which is associated with the location (x,y).
V	getVertex(Layout<V,E> layout, double x, double y) Returns a vertex which is associated with the location (x,y).
Collection<V>	getVertices(Layout<V,E> layout, Shape rectangle) Returns the vertices contained within rectangle relative to layout.

Method Detail

getVertex

V getVertex(Layout<V,E> layout,
            double x,
            double y)

Returns a vertex which is associated with the location (x,y). This is typically determined with respect to the vertex's location as specified by a Layout.

getVertices

Collection<V> getVertices(Layout<V,E> layout,
                          Shape rectangle)

Returns the vertices contained within rectangle relative to layout.

getEdge

E getEdge(Layout<V,E> layout,
          double x,
          double y)

Returns an edge which is associated with the location (x,y). This is typically determined with respect to the edge's location as specified by a Layout.
