The content on demand feature is similar to a tiling
system, such as ilog.views.tiling
, with
the following major differences:
The granularity of content on demand
is an SDM model object, not a tile. However, it is possible to implement
a tiling behavior outside the controller. For example, when the handler
is asked to load an object, all the objects of the same group can
be loaded as well.
Content on demand does not create objects,
it loads and unloads content. In other words, the controller knows
only about the objects currently in the SDM model.
The user has the possibility to load
or unload objects that are not in the visible area.
