public interface IViewPart
A view is a visual component within a workbench page. It is typically used to navigate a hierarchy of information (like the workspace), open an editor, or display properties for the active editor. Modifications made in a view are saved immediately (in contrast to an editor part, which conforms to a more elaborate open-save-close lifecycle).
Only one instance of a particular view type may exist within a workbench page. This policy is designed to simplify part management for a user.
This interface may be implemented directly. For convenience, a base
implementation is defined in ViewPart
.
A view is added to the workbench in two steps:
Views implement the IAdaptable
interface; extensions
are managed by the platform's adapter manager.

The site can be null
while the view is being initialized.
After the initialization is complete, this value must be non-null
for the remainder of the view's life cycle.

This method is automatically called by the workbench shortly after the part is instantiated. It marks the start of the views's lifecycle. Clients must not call this method.
