- Method Detail
  - inEventTime
```
public KeyedStream.IntervalJoin<T1,T2,KEY> inEventTime()
```
    Sets the time characteristic to event time.
  - inProcessingTime
```
public KeyedStream.IntervalJoin<T1,T2,KEY> inProcessingTime()
```
    Sets the time characteristic to processing time.
  - between

@PublicEvolving
public KeyedStream.IntervalJoined<T1,T2,KEY> between(Duration lowerBound,
                                                                 Duration upperBound)
```
    Specifies the time boundaries over which the join operation works, so that
    leftElement.timestamp + lowerBound <= rightElement.timestamp <= leftElement.timestamp + upperBound
    
    By default both the lower and the upper bound are inclusive. This can be configured with KeyedStream.IntervalJoined.lowerBoundExclusive() and KeyedStream.IntervalJoined.upperBoundExclusive()
    Parameters:
    
    lowerBound - The lower bound. Needs to be smaller than or equal to the upperBound
    
    upperBound - The upper bound. Needs to be bigger than or equal to the lowerBound
