Constructor Detail

WebPath

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

Constructs a WebPath using the s from the passed list,

Parameters:

points - a list of WebPoints

WebPath

public WebPath(WebSpatialReference spatialReference)

Constructs an empty WebPath with the given WebSpatialReference.

Parameters:

spatialReference - a spatial reference to be used

WebPath

public WebPath()

Constructs an empty WebPath with null for spatial reference.

Method Detail

getGeometryType

public java.lang.String getGeometryType()

Description copied from class: WebGeometry

Returns a text representing the type of the geometry. WebGeometry objects of the same type must return the same text.

Specified by:

getGeometryType in class WebGeometry

Returns:

a text representing the type of the geometry

toMapGeometry

public WebPath toMapGeometry(WebMap webMap)

Description copied from class: WebGeometry

Converts a geometry in screen coordinates to a geometry of the same type in map coordinates. The coordinate system of the converted geometry is the same as the coordinate system of the WebMap.

Specified by:

toMapGeometry in class WebGeometry

Parameters:

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

Returns:

the WebGeometry in map coordinates

toMapGeometry

public WebPath toMapGeometry(WebExtent extent,
                             int width,
                             int height)

Description copied from class: WebGeometry

Converts a geometry in screen coordinates to a geometry of the same type in map coordinates. The coordinate system of the converted geometry is the same as the coordinate system of the specified extent.

Overrides:

toMapGeometry in class WebGeometry

Parameters:

extent - the WebExtent of the map image

width - the width of the map image

height - the height of the map image

Returns:

the WebGeometry in map coordinates

fromMapGeometry

public WebPath fromMapGeometry(WebMap webMap)

Description copied from class: WebGeometry

Converts a geometry in map coordinates to a geometry of the same type in screen coordinates. Since the converted geometry is a screen geometry, the coordinate system of the converted geometry will be null.

Specified by:

fromMapGeometry in class WebGeometry

Parameters:

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

Returns:

the WebGeometry in screen coordinates

fromMapGeometry

public WebPath fromMapGeometry(WebExtent extent,
                               int width,
                               int height)

Description copied from class: WebGeometry

Converts a geometry in map coordinates to a geometry of the same type in screen coordinates. Since the converted geometry is a screen geometry, the coordinate system of the converted geometry will be null.

Overrides:

fromMapGeometry in class WebGeometry

Parameters:

extent - the WebExtent of the map image

width - the width of the map image

height - the height of the map image

Returns:

the WebGeometry in screen coordinates

project

public WebPath project(WebSpatialReference toSpatialReference)

Description copied from class: WebGeometry

Converts the geometry in map coordinates from the spatialReference of this geometry to a geometry in the desired spatial reference. If the desired spatial reference is same as that of this geometry, this same geometry is returned. Otherwise, a new WebGeometry object is created and populated with the converted coordinates. The type of the projected geometry is same as this geometry.

Specified by:

project in class WebGeometry

Parameters:

toSpatialReference - the desired spatial reference of the projected geometry

Returns:

the projected WebGeometry
