Class WebPointCollection

java.lang.Object
  com.esri.adf.web.data.geometry.WebGeometry
      com.esri.adf.web.data.geometry.WebPointCollection

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

WebMultiPoint, WebPath

public abstract class WebPointCollection
extends WebGeometry

WebPointCollection is a convenience base class for geometries with multiple WebPoints such as WebMultiPoint and WebPath. You can use this as a base class to create geometries representing multiple points of your own. However, consumers of geometries are discouraged from using this class directly and should consider using the concrete implementations of this class such as WebMultiPoint and WebPath.

Constructor Detail

WebPointCollection

public WebPointCollection(java.util.List<? extends WebPoint> points)

Creates a new WebPointCollection object with the given List of WebPoints. All points must be in the same spatial reference. The spatial reference of this collection is extracted from the spatial reference of these points.

Parameters:

points - a List of WebPoints the create this collection

WebPointCollection

public WebPointCollection(WebSpatialReference spatialReference)

Creates a new WebPointCollection in the given spatial reference.

Parameters:

spatialReference - the spatial reference of the WebPointCollection created

Method Detail

getPoints

public java.util.List<WebPoint> getPoints()

Returns the List of WebPoints represented by this point collection.

Returns:

the List of WebPoints represented by this point collection

addPoint

public void addPoint(WebPoint point)

Adds a new WebPoint to the List of WebPoints represented by this point collection.

Parameters:

point - the WebPoint to be added to the List of WebPoints represented by this point collection

toMapPoints

public java.util.List<WebPoint> toMapPoints(WebMap webMap)

Converts the List of screen points in this collection to a List of map points in the coordinate system of the given WebMap. This method is typically used by the sub-classes of this class to convert the points contained by them.

Parameters:

webMap - The WebMap based on which the coordinates need to be converted

Returns:

a List of points in map coordinates

toMapPoints

public java.util.List<WebPoint> toMapPoints(WebExtent extent,
                                            int width,
                                            int height)

fromMapPoints

public java.util.List<WebPoint> fromMapPoints(WebMap webMap)

Converts the List of map points in this collection to a List of screen points. This method is typically used by the sub-classes of this class to convert the points contained by them.

Parameters:

webMap - The WebMap based on which the coordinates need to be converted

Returns:

a List of points in screen coordinates

fromMapPoints

public java.util.List<WebPoint> fromMapPoints(WebExtent extent,
                                              int width,

projectPoints

protected java.util.List<WebPoint> projectPoints(WebSpatialReference toSpatialReference)

Converts the List of map points in this collection from the coordinate system of this geometry to the given coordinate system. This method is typically used by the sub-classes of this class to project the points contained by them.

Parameters:

toSpatialReference - the desired spatial reference of the projected geometry

Returns:

a List of projected points
