- org.opencastproject.metadata.api.util.Interval

```
public abstract class Interval
extends Object
```
An interval in time, possibly unbounded on one end. The interval is described by its bounds which are absolutely placed instants in time with a precision defined by Date.

- Method Detail
  - boundedInterval
```
public static Interval boundedInterval(Date leftBound,
                                       Date rightBound)
```
    Constructor function for a bounded interval.
  - rightBoundedInterval
```
public static Interval rightBoundedInterval(Date rightBound)
```
    Constructor function for a right bounded interval, i.e. an interval with an infinite left endpoint.
  - leftBoundedInterval
```
public static Interval leftBoundedInterval(Date leftBound)
```
    Constructor function for a left bounded interval, i.e. an interval with an infinite right endpoint.
  - fromValues
```
public static Interval fromValues(Date leftBound,
                                  Date rightBound)
```
    Create an interval from two dates. One of the dates may be null to indicate an infinite endpoint.
    
    Throws:
    
    IllegalArgumentException - if boths bounds are null
  - isBounded
```
public boolean isBounded()
```
    Test if both endpoints are not infinite.
  - isLeftInfinite
```
public abstract boolean isLeftInfinite()
```
    Test if the right endpoint is infinite.
  - isRightInfinite
```
public abstract boolean isRightInfinite()
```
    Test if the left endpoint is infinite.
  - fold
```
public abstract <A> A fold(Interval.Match<A> visitor)
```
    Safe decomposition.
