Application programming interfaces for Eclipse Java User Interface specific actions.

## Package Specification

The package provides actions and action groups to populate tool bars, global menu bars and context menus with JDT specific functionality.

It is recommended that clients use action groups to populate menus and tool bars instead of adding actions directly.

Clients are allowed to instantiate classes from this package. The classes are not intended to be subclassed. All actions and groups require that the selection provided by the site, view part or page passed to the action's or group's constructor is of type `org.eclipse.jface.viewers.IStructuredSelection` .
