public class DayOfMonth
extends IntegerBasedExpression

Represents the value of a day in a month, constructed out of a ScheduleExpression.getDayOfMonth()

A DayOfMonth can hold an Integer or a String as its value. value. The various ways in which a DayOfMonth value can be represented are:

• Wildcard. For example, dayOfMonth = "*"
