Class WebMap

java.lang.Object
  com.esri.adf.web.data.WebMap

All Implemented Interfaces:

WebContextInitialize, WebContextObserver, Serializable

public class WebMap
extends Object
implements WebContextInitialize, WebContextObserver, Serializable

The WebMap is an attribute of WebContext (WebMap)context.getAttribute("map"); It defines properties of the map including extent, size, image DPI etc.

A WebMap object generally is defined in the faces-config.xml file of web applications. The following shows how it can be configured as an attribute of the WebContext.

 <managed-bean>
   <managed-bean-name>mapContext</managed-bean-name>
   <managed-bean-class>com.esri.adf.web.data.WebContext</managed-bean-class>
   <managed-bean-scope>request</managed-bean-scope>
   <managed-property>
     <property-name>attributes</property-name>
     <map-entries>
       <map-entry>
         <key>map</key>
         <value>#{webappMap}</value>
       </map-entry>
       .....
 

The object gets instantiated when WebContext initializes. The default settings of a WebMap are:

 <managed-bean>
   <managed-bean-name>webappMap</managed-bean-name>
   <managed-bean-class>com.esri.adf.web.data.WebMap</managed-bean-class>
   <managed-bean-scope>none</managed-bean-scope>
   <managed-property>
     <property-name>imageFormat</property-name>
     <value>PNG</value>
   </managed-property>
 </managed-bean>
 

A WebMap can have a set of functionalities which can be either of type MapFunctionality or TileFunctionality. When the resource is cached, it can have a TileFunctionality, otherwise it is a dynamic resource and have a MapFunctionality.

A set of pre-defined ADF web controls (e.g. MapControl) can work with WebMap to provide extend functions on a map such as map navigation, zoom etc.

The MapControl works with WebMap to render maps. The MapRenderer class renders the control to the appropriate markup, and the MapTag class exposes the control as a JSP custom tag named map.

For users who don't use web controls to manipulate maps, they can use WebMap directly. Following code snippet shows how to create a set of map images with ExportFunctionality.

 //get WebMap from WebContext
 WebMap webMap = webContext.getWebMap();
 
 //specify output size and format etc.
 ExportProperties exportProperties = new ExportProperties();
 exportProperties.setImageFormat(webMap.getImageFormat());
 exportProperties.setDpi(screenDPI); // constant;
 
 exportProperties.setWidth(500);
 exportProperties.setHeight(500);
 exportProperties.setExtent(webMap.getCurrentExtent());
 
 ArrayList<InputStream> imageStreams = new ArrayList<InputStream>();
 Collection<MapFunctionality> mapFuncs = webMap.getMapFunctionalities();
 InputStream is = null;
 
 //Create images for each MapFunctionality
 for (MapFunctionality mf : mapFuncs) {
   if (mf.isDisabled()) {
     continue;
   }
   if (mf instanceof ExportFunctionality) {
     ExportFunctionality exf = (ExportFunctionality) mf;
 
     //create the image byte array.
     is = exf.export(exportProperties);
     if (is != null) {
       imageStreams.add(is);
     }
   }
 }
 

Similarly, user can change layer's visibility or other map definitions with MapFunctionality.

Constructor Detail

WebMap

public WebMap()

Method Detail

init

public void init(WebContext webcontext)

Initializes the WebMap by associating itself with this context. Concrete implementations may want to override this method to do other initialization tasks. This method is called by the ADF when the WebMap is initialized.

Specified by:

init in interface WebContextInitialize

Parameters:

webcontext - WebContext

See Also:

WebContext.init(WebContext), WebContext.addResource(String, GISResource, int), WebContext.removeResource(GISResource)

destroy

public void destroy()

Description copied from interface: WebContextInitialize

The cleaup chores (such as releasing held resources) of attributes of a WebContext should be performed in this method.

Typically this method is called by the WebContext when the context itself is destroyed.

The WebContext attribute is unusable after this method has been called.

Specified by:

destroy in interface WebContextInitialize

See Also:

WebContext.destroy()

update

public void update(WebContext webcontext,
                   Object arg)

Description copied from interface: WebContextObserver

This method is called by the WebContext on its registered WebContextObservers when users call the refresh() methods on the context.

To setup an object to be updated by the context, one needs to use the WebContext.addObserver(WebContextObserver) to register itself with the context. All context attributes are wired up to the WebContext. When users change state on any of the attributes and need to intimate other attributes of the context to react to the change they call either the WebContext.refresh() or WebContext.refresh(Object) methods. The context in turns calls the WebContextObserver.update(WebContext, Object) methods on all its registered observers.

Specified by:

update in interface WebContextObserver

Parameters:

webcontext - the WebContext that has been refreshed

arg - the argument passed to the WebContext's refresh(arg) method

See Also:

WebContext.refresh(Object), WebContext.addObserver(WebContextObserver), WebContext.removeObserver(WebContextObserver)

Gets the tile zoom lever of the current map. When one or more resources of a map have been cached, the map can only be zoomed to certain pre-defined levels. If the returned level is -1 or equal to the return of getTileLevelCount(), it means the map is zoom beyond the cache levels.

Returns:

returns the tile level or -1 if there is no cached tile.

See Also:

By default, when a application contains both cached and dynamic services, it displays data only at cached services’ scale-levels. The dynamic services are fitted into these scale-levels and users won't take full advantage of their dynamic data This property allows users view their dynamic services at arbitrary levels of detail when zooming out of the range of cached services. For example, if a cached service has 3 cache levels: 1:16, 1:32, 1:64. By default the map can only be rendered at those 3 levels. With zoomBeyondCache == true, the map not only can be rendered at those 3 levels, but also can be zoomed out beyond 1:16 and be zoomed in beyond 1:64 if there is a available dynamic service at the given scale.

Returns:

Returns the useCacheLevelsOnly.
