Constructor Detail

NFEFeatureElementSelectionTool

public NFEFeatureElementSelectionTool(MapCanvas canvas,
                                      NFEModel model)

Allocates a new feature element selection tool

Parameters:

canvas - the current MapCanvas

model - the current NFE model

Method Detail

getSelectableGeoObjectPriority

protected int getSelectableGeoObjectPriority(GeoObject geoObj,
                                             java.awt.geom.Point2D srsMousePoint)

Description copied from class: NFESelectionTool

Gets the GeoObject priority to be selected. Selection priority is needed as more than one element may be interacting with the mouse point when selecting.

Specified by:

getSelectableGeoObjectPriority in class NFESelectionTool

Parameters:

geoObj - a selectable GeoObject

srsMousePoint - the mouse point in model's coordinate system

Returns:

getSelectableLayers

protected java.util.Collection<Layer> getSelectableLayers()

Description copied from class: NFESelectionTool

Gets all the layers containing GeoObjects that may be selected by the tool

Specified by:

getSelectableLayers in class NFESelectionTool

Returns:

a collection of layers

deleteSelection

protected void deleteSelection()

Description copied from class: NFESelectionTool

Notifies all the layers to delete its current selected GeoObjects

Specified by:

deleteSelection in class NFESelectionTool

isPoint

protected boolean isPoint(GeoObject geoObj)

Tells whether the GeoObject's shape is a point

Parameters:

geoObj - a GeoObject

Returns:

true if the GeoObject is a point
