| ImageRenderSupport | | public interface ImageRenderSupport (Code) | | An optional interface which may be implemented by
ComponentSynchronizePeers to render images via the
ImageRenderService.
|
| Method Summary | |
| public ImageReference | getImage(Component component, String imageId)
Retrieves the image identified by the given imageId value
for the given Component.
Note: A reference to any images to be rendered must be
maintained throughout the rendering process, due to the fact that the
image rendering subsystem creates a weak-keyed cache of images to be
rendered. |
| getImage | | public ImageReference getImage(Component component, String imageId)(Code) | | Retrieves the image identified by the given imageId value
for the given Component.
Note: A reference to any images to be rendered must be
maintained throughout the rendering process, due to the fact that the
image rendering subsystem creates a weak-keyed cache of images to be
rendered. This method therefore may not simply return a new,
otherwise-unreferenced image. In the event that this presents a problem,
the recommended workaround is to simply store such otherwise unreferenced
ImageReferences using a RenderState object.
Parameters:
component - the component
Parameters:
imageId - the id of the image the target image |
