Deprecated.

Method Detail

initFunctionality

public void initFunctionality(GISResource resource)

Deprecated.

Initializes an instance of the overview functionality for this resource.

Specified by:

initFunctionality in interface GISFunctionality

Parameters:

resource - the GISResource that this functionality supports

See Also:

GISResource.init(WebContext)

destroyFunctionality

public void destroyFunctionality()

Deprecated.

Description copied from interface: GISFunctionality

The cleanup chores (such as releasing held resources) for the functionality must be performed in this method. This method is called by the GISResource when the resource itself is being destroyed.

The functionality is no longer usable after this method has been called.

Specified by:

destroyFunctionality in interface GISFunctionality

See Also:

GISResource.destroy()

getResource

public EJBMapResource getResource()

Deprecated.

Description copied from interface: GISFunctionality

Returns the GISResource associated with this functionality.

The resource passed to GISFunctionality.initFunctionality(GISResource) is maintained as a class variable and is accessible through this method.

Specified by:

getResource in interface GISFunctionality

Returns:

the GISResource associated with this functionality

exportImage

public java.io.InputStream exportImage()

Deprecated.

Description copied from interface: OverviewFunctionality

Exports this overview map for the extent indicated by the WebOverview. Implementations should ensure the following:

• The map should be exported in the spatial reference of the associated WebContext.
• The map should be exported for the extent indicated by the WebOverview. The WebOverview.getDrawExtent() method can be used to get this extent.

The WebOverview calls this method on all its overview functionalities and eventually fuses all the exported maps before streaming it to the user. This method is called by the WebOverview in these scenarios:

• When the WebOverview is initialized
• When a resource is dynamically added or removed
• When any overview functionality is enabled or disabled

Specified by:

exportImage in interface OverviewFunctionality

Returns:

a java.io.InputStream to the exported image

isDisabled

public boolean isDisabled()

Deprecated.

Description copied from interface: OverviewFunctionality

Returns true if this overview functionality is disabled. If a overview functionality is disabled, the WebOverview will not call the OverviewFunctionality.exportImage() on that functionality while it is disabled.

A overview functionality is typically disabled by using the "Disable Overview" context menu item on the resource node in the Table of Contents control. Similarly, the functionality can be enabled by using "Enable Overview".

Specified by:

isDisabled in interface OverviewFunctionality

Returns:

true if this overview functionality is disabled

setDisabled

public void setDisabled(boolean disabled)

Deprecated.

Description copied from interface: OverviewFunctionality

If true, this overview functionality is disabled. If a overview functionality is disabled, the WebOverview will not call the OverviewFunctionality.exportImage() on that functionality while it is disabled.

A overview functionality is typically disabled by using the "Disable Overview" context menu item on the resource node in the Table of Contents control. Similarly, the functionality can be enabled by using "Enable Overview".

Specified by:

setDisabled in interface OverviewFunctionality

Parameters:

disabled - true if this overview functionality is disabled

fromMapPoint

@Deprecated
public WebPoint fromMapPoint(WebPoint mapPoint)

Deprecated. As of ArcGIS Java Server 9.3, instead use WebPoint.fromMapGeometry(WebExtent, int, int)

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.

Parameters:

mapPoint - the point to be converted in screen coordinates

Returns:

the screen coordinates of the given point

toMapPoint

@Deprecated
public WebPoint toMapPoint(WebPoint screenPoint)

Deprecated. As of ArcGIS Java Server 9.3, instead use WebPoint.toMapGeometry(WebExtent, int, int)

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

Parameters:

screenPoint - the point to be converted in map coordinates

Returns:

the map coordinates of the given point
