org.eclipse.jface.fieldassist.FieldDecorationRegistry

FieldDecorationRegistry is a common registry used to define shared field decorations within an application. Unlike resource registries, the FieldDecorationRegistry does not perform any lifecycle management of the decorations.

Clients may specify images for the decorations in several different ways. Images may be described by their image id in a specified {@link ImageRegistry}. In this case, the life cycle of the image is managed by the image registry, and the decoration registry will not attempt to obtain an image from the image registry until the decoration is actually requested. In cases where the client has access to an already-created image, the image itself can be specified when registering the decoration. In this case, the life cycle should be managed by the specifying client.
