public class RadiusPickSupport<V,E> extends RadiusGraphElementAccessor<V,E> implements GraphElementAccessor<V,E>
Simple implementation of PickSupport that returns the vertex or edge that is closest to the specified location. This implementation provides the same picking options that were available in previous versions of AbstractLayout.- Author:

getVertex
public V getVertex(Layout<V,E> layout, double x, double y)
Gets the vertex nearest to the location of the (x,y) location selected, within a distance of maxDistance. Iterates through all visible vertices and checks their distance from the click. Override this method to provide a more efficient implementation.- Specified by:
getVertex
in interfaceGraphElementAccessor<V,E>
- Overrides:
getVertex
in classRadiusGraphElementAccessor<V,E>
- Parameters:
layout
- the context in which the location is definedx
- the x coordinate of the locationy
- the y coordinate of the location- Returns:
- a vertex which is associated with the location
(x,y)
as given bylayout

getVertex
public V getVertex(Layout<V,E> layout, double x, double y, double maxDistance)
Gets the vertex nearest to the location of the (x,y) location selected, within a distance of maxDistance. Iterates through all visible vertices and checks their distance from the click. Override this method to provide a more efficient implementation.- Overrides:
getVertex
in classRadiusGraphElementAccessor<V,E>
- Parameters:
layout
- the layout instance that records the positions for all verticesx
- the x coordinate of the pick pointy
- the y coordinate of the pick pointmaxDistance
- vertices whose from (x, y) is > this cannot be returned- Returns:
- the vertex whose center is closest to the pick point (x, y)
-
getEdge
public E getEdge(Layout<V,E> layout, double x, double y)
Gets the edge nearest to the location of the (x,y) location selected. Calls the longer form of the call.- Specified by:
getEdge
in interfaceGraphElementAccessor<V,E>
- Overrides:
getEdge
in classRadiusGraphElementAccessor<V,E>
- Parameters:
layout
- the layout instance that records the positions for all verticesx
- the x coordinate of the pick pointy
- the y coordinate of the pick point- Returns:
- the vertex whose center is closest to the pick point (x, y)
-
getEdge
public E getEdge(Layout<V,E> layout, double x, double y, double maxDistance)
Gets the edge nearest to the location of the (x,y) location selected, within a distance of maxDistance, Iterates through all visible edges and checks their distance from the click. Override this method to provide a more efficient implementation.- Overrides:
getEdge
in classRadiusGraphElementAccessor<V,E>
- Parameters:
x
- the x coordinate of the pick pointy
- the y coordinate of the pick pointmaxDistance
- vertices whose from (x, y) is > this cannot be returnedlayout
- the context in which the location is defined- Returns:
- Edge closest to the click.
