* Otherwise a new breakpoint will be created.
* @param interactive If true the toggle adapter should open a dialog before creating a
* breakpoint, or open a properties dialog on an existing breakpoint.
* @param part Workbench part where the toggle action is to be executed.
* @param selection Variable on which to execute the toggle action.
