Item
is an object that contains a set of named
properties. Each property is identified by a property identifier (PID) and a
reference to the property can be queried from the
Item
. Item
defines inner interfaces
for maintaining the item property set and listening changes in the item property
set.
Items generally represent objects in the object-oriented model, but with the
exception that they are configurable and provide an event mechanism. The simplest
way of utilizing Item
interface is to use existing Item
implementations. Provided utility classes include a configurable property set, a
bean-to-item adapter and a Form UI component.
