- getId()
- StyleContent(String)
- getStyleClass()
- save(IMemento, Object)
- load(IMemento)
- load(URL, IProgressMonitor)
- createDefaultStyle(IGeoResource, Color, IProgressMonitor)
IPersister<T>
- setExtension(IExtension)
- getExtension()
- getPersistee()
- load(IMemento)
- save(T, IMemento)
Notes:
- main actual difference in their intent is the need of a StyleContent to make a good default style, and the possibility of it making a style from a provided URL.
- I would like to hava StyleContent extend IPersister to cut down on duplication.
There have also been a couple of attempts at persisting things "by default" even if a programmer has not explicitly provided instructions.
In BlackboardImpl there is an else statement that uses serializable:
// try serializability
if (entry.getObjectClass() != null
&& entry.getObjectClass().isAssignableFrom(Serializable.class)) {
ByteArrayInputStream bin = new ByteArrayInputStream(memento2
.getBytes());
ObjectInputStream in = new ObjectInputStream(new BufferedInputStream(
bin));
object = in.readObject();
in.close();
entry.setObject(object);
entry.setObjectClass(object.getClass());
} else {
// either object not serializable, or type can not
// derminated
}
Notes:
-The above code was commented out as the renderer was using it to keep a String of the last renderer chosen preventing render metics based switch overs from occurring)
- There is one ColorPersister implemented for uDig
In StyleBlackboard I have added a StyleContent.DEFAULT that performs a similar function.
