const integer EXCLUDE_START_DATE = 1 ;

/* 属性 */

public integer $recurrences ;

public boolean $include_start_date ;

public DateTimeInterface $start ;

public DateTimeInterface $current ;

public DateTimeInterface $end ;

public DateInterval $interval ;

/* 方法 */

public __construct ( DateTimeInterface $start , DateInterval $interval , int $recurrences [, int $options ] )

public __construct ( DateTimeInterface $start , DateInterval $interval , DateTimeInterface $end [, int $options ] )

public __construct ( string $isostr [, int $options ] )

public DateInterval getDateInterval ( void )

public DateTimeInterface getEndDate ( void )

public DateTimeInterface getStartDate ( void )

}
