Detailed Description

Polygon encloses an arbitrary 2-dimensional area on a Map. Polygons can be used for drawing a perimeter, such as a campus, city, or country. Polygons begin as basic triangles. New vertices can be created by dragging the midpoint of a polygon away from the edge. Clicking on a vertex will remove the vertex, but a minimum of 3 vertices must exist at all times.

Constructor & Destructor Documentation

◆ Polygon()

com.google.appinventor.components.runtime.Polygon.Polygon ( MapFactory.MapFeatureContainer container )

Definition at line 110 of file Polygon.java.

Member Function Documentation

◆ Centroid()

YailList com.google.appinventor.components.runtime.Polygon.Centroid ( )

Gets the centroid of the Polygon as a (latitude, longitude) pair.

Reimplemented from com.google.appinventor.components.runtime.MapFeatureBase.

Definition at line 308 of file Polygon.java.

◆ computeGeometry()

Geometry com.google.appinventor.components.runtime.Polygon.computeGeometry ( )

protected

Reimplemented from com.google.appinventor.components.runtime.MapFeatureBase.

Definition at line 328 of file Polygon.java.

◆ getHolePoints()

List<List<List<GeoPoint> > > com.google.appinventor.components.runtime.Polygon.getHolePoints ( )

Gets the hole points for the (multi-)polygon, if any, in GeoPoint format.

Returns: a list of lists of lists of GeoPoint, where each element in the outermost list corresponds to a polygon defined at the n-th position in getPoints().

Implements com.google.appinventor.components.runtime.util.MapFactory.MapPolygon.

Definition at line 318 of file Polygon.java.

◆ getPoints()

List<List<GeoPoint> > com.google.appinventor.components.runtime.Polygon.getPoints ( )

Gets the points defining the (multi-)polygon in GeoPoint format.

Returns: a list of lists of GeoPoint. Note that this is consistent with the multipolygon format and for single polygons the size of the list will be 1.

Implements com.google.appinventor.components.runtime.util.MapFactory.MapPolygon.

Definition at line 313 of file Polygon.java.

◆ HolePoints() [1/2]

YailList com.google.appinventor.components.runtime.Polygon.HolePoints ( )

Gets the list of points defining holes in the polygon, in (lat, long) format. If the polygon is actually a multipolygon, this will return a list of lists of lists, with each element in the outer list corresponding to one of the polygon parts defined in Points().

Returns: a list of the polygon's hole points.

Implements com.google.appinventor.components.runtime.util.MapFactory.MapPolygon.

Definition at line 221 of file Polygon.java.

◆ HolePoints() [2/2]

void com.google.appinventor.components.runtime.Polygon.HolePoints ( YailList points )

Specifies the points of any holes in the Polygon. The HolePoints property is a list of lists, with each sublist containing (latitude, longitude) points representing a hole.

Parameters

points a list of lists of lists defining the holes in each part of the multipolygon.

Implements com.google.appinventor.components.runtime.util.MapFactory.MapPolygon.

Definition at line 243 of file Polygon.java.

◆ HolePointsFromString()

void com.google.appinventor.components.runtime.Polygon.HolePointsFromString ( String pointString )

Specifies holes in a Polygonfrom a GeoJSON string. In contrast to HolePoints(YailList), the longitude of each point comes before the latitude as stated in the GeoJSON specification.

Parameters

pointString

Definition at line 277 of file Polygon.java.

◆ Initialize()

void com.google.appinventor.components.runtime.Polygon.Initialize ( )

Definition at line 115 of file Polygon.java.

◆ Points() [1/2]

YailList com.google.appinventor.components.runtime.Polygon.Points ( )

Gets the list of points defining the polygon, in (lat, long) format. If the polygon is actually a multipolygon, this will return a list of lists of points, with each element in the outer list representing a portion of the multipolygon.

Returns: a list of the polygon's points.

Implements com.google.appinventor.components.runtime.util.MapFactory.MapPolygon.

Definition at line 134 of file Polygon.java.

◆ Points() [2/2]

void com.google.appinventor.components.runtime.Polygon.Points ( YailList points )

Specifies the Points used for drawing the Polygon. The Points are specified as a list of lists containing latitude and longitude values, such as [[lat1, long1], [lat2, long2], ...].

Parameters

points a list of points defining the polygon.

Implements com.google.appinventor.components.runtime.util.MapFactory.MapPolygon.

Definition at line 158 of file Polygon.java.

◆ PointsFromString()

void com.google.appinventor.components.runtime.Polygon.PointsFromString ( String pointString )

Specifies the points for the Polygon from a GeoJSON string. Unlike Points(YailList), this property expects that the longitude comes first in the point rather than the latitude.

Parameters

pointString

Definition at line 189 of file Polygon.java.

◆ Type()

String com.google.appinventor.components.runtime.Polygon.Type ( )

The type (class) of the map feature. Typically this should be getClass().getSimpleName().

Returns: string representing the type of the feature

Implements com.google.appinventor.components.runtime.util.MapFactory.MapFeature.

Definition at line 127 of file Polygon.java.

◆ updateHolePoints()

void com.google.appinventor.components.runtime.Polygon.updateHolePoints ( List< List< List< GeoPoint >>> points )

Updates the internal representation of the hole points for the (multi-)polygon. This is intended to only be called to finalize a drag operation so that the internal representation is consistent with the final visual location of the polygon at the end of the drag. NB: This should not invalidate the map view.

Parameters

points the lists of ring lists representing the new hole locations for the (multi-)polygon.

Implements com.google.appinventor.components.runtime.util.MapFactory.MapPolygon.

Definition at line 340 of file Polygon.java.

◆ updatePoints()

void com.google.appinventor.components.runtime.Polygon.updatePoints ( List< List< GeoPoint >> points )

Updates the internal representation of the points defining the polygon. This is intended to only be called to finalize a drag operation so that the internal representation is consistent with the final visual location of the polygon at the end of the drag. NB: This should not invalidate the map view.

Parameters

points the ring list representing the new points for the (multi-)polyon.

Implements com.google.appinventor.components.runtime.util.MapFactory.MapPolygon.
