he Component Editor (design-time wrapper), Component Handler
(design-time support), Component Executor (runtime wrapper), and Component
Postprocessor (post-execution support) provide all the necessary functionality
for the component.
However, Isight
must know how to access these wrappers and must be provided with other
supporting information for the component to work properly within the
Isight
environment. This information is specified in an XML file called the
Component Descriptor. Although a Descriptor can be created manually,
the SDK Generator (discussed later) will create one automatically based
on information you provide (allowing the SDK Generator to create a Descriptor
manually is recommended to avoid syntactical errors).
