Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`long`	`getExecutionInterval()` Retrieve the execution interval.
`int`	`getNumberOfTimesToExecute()` Retrieves the number of times the operation needs to be executed.
`boolean`	`isExcuteAFixedNumberOfTimes()` Indicates whether the operation needs to be executed a fixed number of times
`boolean`	`isExecuteOnce()` This indicates if the operation needs to be executed exactly once
`boolean`	`isExecutePeriodically()` Indicates whether the operation needs to be executed periodically.
`boolean`	`isExecuteWhenDataAvailable()` This indicates that the operation should be run when new data is made available on its input datasets.
`boolean`	`isStayAlive()` This indicates that the operation should be allowed to continually run until the operation deems necessary.

- Method Detail
  - isExecuteOnce
```
boolean isExecuteOnce()
```
    This indicates if the operation needs to be executed exactly once
    
    Returns:
    
    true if this is to be executed once; false otherwise.
  - isExecutePeriodically
```
boolean isExecutePeriodically()
```
    Indicates whether the operation needs to be executed periodically.
    
    Returns:
    
    true if this is to be executed periodically; false otherwise.
  - isExcuteAFixedNumberOfTimes
```
boolean isExcuteAFixedNumberOfTimes()
```
    Indicates whether the operation needs to be executed a fixed number of times
    
    Returns:
    
    true if the operation needs to be executed a fixed number of times;false otherwise.
  - getExecutionInterval
```
long getExecutionInterval()
```
    Retrieve the execution interval. A value of 0 indicates that the operation needs not be executed periodically. The upper-bound for this value depends on the policies at individual nodes
    
    Returns:
    
    The execution interval.
  - getNumberOfTimesToExecute
```
int getNumberOfTimesToExecute()
```
    Retrieves the number of times the operation needs to be executed.
    
    Returns:
    
    The number of times, which the operation needs to be executed.
  - isStayAlive
```
boolean isStayAlive()
```
    This indicates that the operation should be allowed to continually run until the operation deems necessary. When the operation is ready to terminate, the operation needs to assert the terminationConditionReached flag. This is particularly useful for operations that need to run until a certain condition has been satisfied.
    
    Returns:
    
    true if this is stay alive; false otherwise.
  - isExecuteWhenDataAvailable
```
boolean isExecuteWhenDataAvailable()
```
    This indicates that the operation should be run when new data is made available on its input datasets. This is especially useful for streaming datasets where data is continually arriving, each of which needs to be processed.
    
    Returns:
    
    true if this is execute when data is available; false otherwise.
