public class ADFUtil
extends Object

This class contains the utility methods that can be used within the ADF core objects.

Method Summary

static <T extends Serializable> T	copy(T src) Create a copy of the specified Serializable object.
static boolean	isGeoTransformAvailable(WebSpatialReference sr1, WebSpatialReference sr2) Indicates whether a geotransformation is available between these two spatial references.
static WebExtent	reaspect(WebExtent extent, double width, double height) Adjusts the current envelope based on the aspect ratio of the given width and height.

Method Detail

reaspect

public static WebExtent reaspect(WebExtent extent,
                                 double width,
                                 double height)

Adjusts the current envelope based on the aspect ratio of the given width and height.

Parameters:

extent - the extent to be reaspect

width - the image width in pixels.

height - the image height in pixels.

Returns:

the reaspected extent

copy

public static <T extends Serializable> T copy(T src)
                                   throws ADFException

Create a copy of the specified Serializable object.

Parameters:

src - the object to create a copy

Returns:

the copy of the specified object

Throws:

ADFException

isGeoTransformAvailable

public static boolean isGeoTransformAvailable(WebSpatialReference sr1,
                                              WebSpatialReference sr2)

Indicates whether a geotransformation is available between these two spatial references. Use this method to find out if two resources with different spatial references can be used together, or if the WebContext can be safely reprojected to a new spatial reference.

Parameters:

sr1 - from spatial reference

sr2 - to spatial reference

Returns:

boolean true, if geotransformation available
