question: @ Override public boolean close ( ) { if ( lastOpenedTime != - 1 ) { final long elapsedTimeOpen = System . currentTimeMillis ( ) - lastOpenedTime ; DialogSettingsHelper . recordDialogClosed ( dialogSettingsKey , elapsedTimeOpen ) ; lastOpenedTime = - 1 ; } DialogSettingsHelper . persistShellGeometry ( getShell ( ) , dialogSettingsKey ) ; hookDialogAboutToClose ( ) ; return super . close ( ) ; }
target:  This base class overrides close() to persist the dialog settings, record the elapsed open time for statistics, and to call a subclass hook.
