| IMAGE_REQUESTED | | final protected static String IMAGE_REQUESTED(Code) | | Constant used to indicate that an image has been requested to the
ExternalResourceHandler but that the handler has not delivered the
result yet.
|
| documentLoaded | | protected boolean documentLoaded(Code) | | Set to true once the associated DocumentNode has fully loaded.
|
| loaderUtil | | protected ImageLoaderUtil loaderUtil(Code) | | ImageLoaderUtil contains helper methods which make this
implementation easier.
|
| pendingNeedsURI | | protected Vector pendingNeedsURI(Code) | | Keeps track of pending absoluteURI requests.
|
| rasterImageConsumerTable | | protected Hashtable rasterImageConsumerTable(Code) | | Simple hashtable used to track ImageNode objects.
|
| svgImage | | protected SVGImageImpl svgImage(Code) | | The SVGImage associated to this SVGImageLoader
|
| SVGImageLoader | | public SVGImageLoader(SVGImageImpl svgImage, ExternalResourceHandler handler)(Code) | | Constructor
Parameters:
svgImage - the associated SVGImage, should not be null.
Parameters:
handler - the ExternalResourceHandler which will get the images data. |
| addRasterImageConsumer | | public void addRasterImageConsumer(String absoluteURI, RasterImageConsumer imageNode)(Code) | | In cases where the ImageLoader may update the images associated to a URI,
RasterImageConsumer interested in updates need to register their interest
throught this method.
Parameters:
absoluteURI - the URI the RasterImageConsumer is interested in.
Parameters:
imageNode - the RasterImageConsumer interested in the URI. |
| addToCache | | void addToCache(String uri, Object image)(Code) | | Adds image to the Image cache.
Parameters:
uri - the key for the Image cache.
Parameters:
image - the Image to store. |
| allowsRelativeURI | | public boolean allowsRelativeURI()(Code) | | Determines whether this ImageLoader can handle relative uri's
true if this ImageLoader can handle relative uri's;false otherwise. |
| documentLoaded | | public void documentLoaded(DocumentNode doc)(Code) | | Some ImageLoader implementations may wish to wait until the end of the
Document load to start retrieving resources. This method notifies
the implementation that the DocumentNode completed loading successfully.
Parameters:
doc - the DocumentNode which just finised loading. |
| getImageAndWait | | public RasterImage getImageAndWait(String uri)(Code) | | Requests the given image. This call blocks until an image is
returned.
Parameters:
uri - the requested URI. the loaded image or the same image as returned bya getBrokenImage call if the image couldnot be loaded. |
| getImageFromCache | | public RasterImage getImageFromCache(String uri)(Code) | | Returns the Image that was previously loaded.
Parameters:
uri - the key for the Image cache. the Image associated with the key. |
| getImageLater | | public void getImageLater(String uri, RasterImageConsumer rasterImageConsumer)(Code) | | Requests the given image. This call returns immediately and
the image is set on the input ImageNode when the
image becomes available.
Parameters:
uri - the requested URI.
Parameters:
rasterImageConsumer - the RasterImageConsumer whose image member should be set as a result of loading the image. |
| needsURI | | public void needsURI(String absoluteURI)(Code) | | Notifies the URILoader that the given uri will be needed.
Parameters:
absoluteURI - the requested URI content. |
| needsURIDocumentLoaded | | protected void needsURIDocumentLoaded(String absoluteURI)(Code) | | In SVGImageLoader, we wait until the document has been loaded before
acting on required raster images.
Parameters:
absoluteURI - the requested URI content. |
| removeRasterImageConsumer | | public void removeRasterImageConsumer(String absoluteURI, RasterImageConsumer imageNode)(Code) | | In cases where the ImageLoader may update the images associated to a URI,
RasterImageConsumer interested in updates need to de-register their
interest throught this method.
Parameters:
absoluteURI - the URI the RasterImageConsumer is interested in.
Parameters:
imageNode - the RasterImageConsumer interested in the URI. |
| setRasterImageConsumerImage | | void setRasterImageConsumerImage(String uri, RasterImage image)(Code) | | Implementation helper.
Parameters:
uri - the uri identifying the image resource.
Parameters:
image - the RasterImage to send to the consumers. |
