public class ContainerNodeEditPolicy

extends GraphicalNodeEditPolicy

This is installed on a container editpart. It is responsible for creating connections from a source shape to an unspecified target and a target shape to an unspecified source. A popup will appear asking the user to select or create a new source or target element. This will handle both single create connection requests and multi connection requests (i.e. where the popup also prompts the user for the type of relationship to created).
