public GeometryOperations()

Method Detail

getDefaultInstance

public static final GeometryOperations getDefaultInstance()

Returns the implementation for performing geometric operations. By default an instance of WebGeometryOperations is used.

Returns:

the default instance

setDefaultInstance

public static final void setDefaultInstance(GeometryOperations operations)

Sets the instance that should be used for performing geometric operations. This instance must be thread-safe. By default an instance of WebGeometryOperations is used. This method should be called only once, subsequent invocations will not have any effect.

Parameters:

operations - a concrete implementation of GeometryOperations class

project

public abstract List<WebGeometry> project(List<? extends WebGeometry> geometries,
                                          WebSpatialReference toSR)

Projects the list of geometries to the specified spatial reference. Also all the geometries that are passed must be in the same spatial reference.

Parameters:

geometries - the geometries to project

toSR - the spatial reference to which the geometries are to be projected

Returns:

a java.util.List of projected geometries

project

public abstract WebGeometry project(WebGeometry geometry,
                                    WebSpatialReference toSR)

Projects the geometry to the specified spatial reference.

Parameters:

geometry - the geometry to project

toSR - the spatial reference to which the geometry to be projected

Returns:

the projected geometry

toString

public abstract String toString()

Returns the user friendly name for the concrete implementation class.

Overrides:

toString in class Object
