There is a third way to define the structure (single assembler as one,
the one you mention being the other), and it works similar to what you
ask, see http://www.qi4j.org/70.html in the Explicit Assembly section
for a full example.
ApplicationAssembly app = factory.newApplicationAssembly();
LayerAssembly layer1 = app.newLayerAssembly();
ModuleAssembly moduleA = layer.newModuleAssembly():
moduleA.addComposites(... );
:
ApplicationContext context = factory.newApplication( app );
Very explicit. Since Layers are not necessarily like pancakes on top
of each other, I think it will be hard to come up with a good fluent
API to express it, and hence we went with the Array declaration
instead.
