ImageLoader

Fields Summary

Constructors Summary

Methods Summary
public void	addRasterImageConsumer(java.lang.String absoluteURI, RasterImageConsumer imageNode) 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. param absoluteURI the URI the RasterImageConsumer is interested in. param imageNode the RasterImageConsumer interested in the URI.
public boolean	allowsRelativeURI() Determines whether this ImageLoader can handle relative uri's return true if this ImageLoader can handle relative uri's; false otherwise.
public void	documentLoaded(DocumentNode doc) 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 associated DocumentNode completed loading successfully. param doc the DocumentNode which just finised loading.
public com.sun.perseus.j2d.RasterImage	getBrokenImage() Returns the image that should be used to represent an image which could not be loaded. return the image to represent broken uris or content.
public com.sun.perseus.j2d.RasterImage	getImageAndWait(java.lang.String uri) Requests the given image. This call blocks until an image is returned. param uri the requested URI. Should be a resolved URI. return the loaded image or the same image as returned by a getBrokenImage call if the image could not be loaded.
public void	getImageLater(java.lang.String uri, RasterImageConsumer imageNode) Requests the given image. This call returns immediately and the image is set on the input ImageNode when the image becomes available. param uri the requested URI. Should be a resolved URI. param imageNode the ImageNode whose image member should be set as a result of loading the image.
public com.sun.perseus.j2d.RasterImage	getLoadingImage() Returns the image that should be used to represent an image which is loading. return the image to use to represent a pending loading.
public void	needsURI(java.lang.String absoluteURI) Notifies the URILoader that the given uri will be needed. param absoluteURI the requested URI content.
public void	removeRasterImageConsumer(java.lang.String absoluteURI, RasterImageConsumer imageNode) 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. param absoluteURI the URI the RasterImageConsumer is interested in. param imageNode the RasterImageConsumer interested in the URI.
public java.lang.String	resolveURI(java.lang.String uri, java.lang.String baseURI) Resolves the input relative and base URI into an absolute URI which can be used in subsequent calls to needsURI, getImageAndWait or getImageLater calls. param uri the requested URI content. param baseURI the base URI. Needed in case uri is relative. return the resolved URI that should be requested in follow on needsURI, getImageAndWait or getImageLater calls or null if the URI cannot be resolved.
