java.util.Collection<GeoObject> getVertexEditableGeoObjects()

Gets all the GeoObjects which vertices can be edited

Returns:

a collection of GeoObjects

getVertices

double[] getVertices(GeoObject geoObj)

Gets all the vertices of the GeoObject

Parameters:

geoObj - a GeoObject

Returns:

an array containing the ordinates of the GeoObject's vertices

getSnapPoint

JGeometrySegmentPoint getSnapPoint(GeoObject geoObj,
                                   java.awt.geom.Point2D point,
                                   double tolerance)

Parameters:

geoObj - a GeoObject

point - a point in model's coordinate system

tolerance - a tolarence in model's coordinate system

Returns:

a segment point relative to the GeoObject's geometry

canAddVertex

boolean canAddVertex(GeoObject geoObj,
                     JGeometrySegmentPoint snapPoint)

Parameters:

geoObj - a GeoObject

snapPoint - a segment point relative to the GeoObject's geometry

Returns:

true if it is possible to add a new vertex

addVertex

boolean addVertex(GeoObject geoObj,
                  JGeometrySegmentPoint snapPoint)

Adds a vertex to the given GeoObject at the specified snap point

Parameters:

geoObj - a GeoObject

snapPoint - a segment point relative to the GeoObject's geometry

Returns:

true if the vertex was successfully added
