Methods
Modifier and Type	Method and Description
`E`	`getEdge(edu.uci.ics.jung.algorithms.layout.Layout<V,E> layout, double x, double y)` return an edge whose shape intersects the 'pickArea' footprint of the passed x,y, coordinates.
`V`	`getVertex(edu.uci.ics.jung.algorithms.layout.Layout<V,E> layout, double x, double y)` Iterates over Vertices, checking to see if x,y is contained in the Vertex's Shape.
`java.util.Collection<V>`	`getVertices(edu.uci.ics.jung.algorithms.layout.Layout<V,E> layout, java.awt.Shape rectangle)` returns the vertices that are contained in the passed shape.

public ViewLensShapePickSupport(VisualizationServer<V,E> vv,
                        float pickSize)
```
    Create an instance. The HasGraphLayout is used as the source of the current Graph Layout. The HasShapes is used to access the VertexShapes and the EdgeShapes
    
    Parameters:
    hasGraphLayout - source of the current layout.
    hasShapeFunctions - source of Vertex and Edge shapes.
    pickSize - how large to make the pick footprint for line edges
  - ViewLensShapePickSupport
```
public ViewLensShapePickSupport(VisualizationServer<V,E> vv)
```
    Create an instance. The pickSize footprint defaults to 2.

  - getVertex
```
public V getVertex(edu.uci.ics.jung.algorithms.layout.Layout<V,E> layout,
          double x,
          double y)
```
    Iterates over Vertices, checking to see if x,y is contained in the Vertex's Shape. If (x,y) is contained in more than one vertex, use the vertex whose center is closest to the pick point.

                                  java.awt.Shape rectangle)
```
    returns the vertices that are contained in the passed shape. The shape is in screen coordinates, and the graph vertices are transformed to screen coordinates before they are tested for inclusion
    
    Specified by:
    
    getVertices in interface edu.uci.ics.jung.algorithms.layout.GraphElementAccessor<V,E>
    
    Overrides:
    
    getVertices in class ShapePickSupport<V,E>
    
    Returns:
    the Collection of vertices whose layout coordinates are contained in shape.

```
public E getEdge(edu.uci.ics.jung.algorithms.layout.Layout<V,E> layout,
        double x,
        double y)
```
    return an edge whose shape intersects the 'pickArea' footprint of the passed x,y, coordinates.
