DateRange
public DateRange(java.util.Date lower, java.util.Date upper)
Constructs a new range.- Parameters:
lower
- the lower bound (null
not permitted).upper
- the upper bound (null
not permitted).
-
DateRange
public DateRange(double lower, double upper)
Constructs a new range using two values that will be interpreted as "milliseconds since midnight GMT, 1-Jan-1970".- Parameters:
lower
- the lower (oldest) date.upper
- the upper (most recent) date.
-
DateRange
public DateRange(Range other)
Constructs a new range that is based on anotherRange
. The other range does not have to be aDateRange
. If it is not, the upper and lower bounds are evaluated as milliseconds since midnight GMT, 1-Jan-1970.- Parameters:
