TimestampTallyInterface (DJUTILS statistical and data storage utilities 1.06.28 API)

All Superinterfaces:

BasicTallyInterface, Serializable, WeightedTallyInterface

All Known Implementing Classes:

EventBasedTimestampWeightedTally, TimestampWeightedTally
```
public interface TimestampTallyInterface
extends WeightedTallyInterface
```
The TimestampedTally interface defines the methods that a timestamped tally should implement in addition to the standard weighted tally. Timestamps can, e.g., be Number based or Calendar based.

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`endObservations(Number timestamp)`	End the observations and closes the last interval of observations.
`void`	`endObservations(Calendar timestamp)`	End the observations and closes the last interval of observations.

- Method Detail
  - isActive
```
boolean isActive()
```
    Return whether the statistic is active (accepting observations) or not.
    
    Returns:
    
    boolean; whether the statistic is active (accepting observations) or not
  - endObservations
```
void endObservations(Number timestamp)
```
    End the observations and closes the last interval of observations. After ending, no more observations will be accepted. Calling this method will create an extra observation, and corresponding events for the EventBased implementations of this interface will be called.
    
    Parameters:
    
    timestamp - Number; the Number object representing the final timestamp
  - endObservations
```
void endObservations(Calendar timestamp)
```
    End the observations and closes the last interval of observations. After ending, no more observations will be accepted. Calling this method will create an extra observation, and corresponding events for the EventBased implementations of this interface will be called.
    
    Parameters:
    
    timestamp - Calendar; the Calendar object representing the final timestamp
