Executor (Siddhi Core 5.1.29 API)

All Known Implementing Classes:

EntryValveExecutor, IncrementalExecutor, PersistedIncrementalExecutor
```
public interface Executor
```
This is the parent interface representing Event executor for incremental execution in Siddhi. Each event executor (IncrementalExecutor) corresponds to a duration specified in TimePeriod.Duration. Apart from that, EntryValveExecutor which is a special implementation of this interface, marks the entry point to the rest of the incremental executors. All of these executors are chained in such a way, that EntryValveExecutor links to the first IncrementalExecutor corresponding to the minimum duration, and the rest of the IncrementalExecutors link in ascending order of durations. A ComplexEventChunk received by a certain executor would thus be handed over to next executor in-line.

- Method Detail
  - execute
```
void execute(ComplexEventChunk complexEventChunk)
```
    Execute the handed StreamEvent
    
    Parameters:
    
    complexEventChunk - event chunk to be processed
  - getNextExecutor
```
Executor getNextExecutor()
```
    Get next executor element in the execution chain. Executed event should be sent to next executor
    
    Returns:
    
    next executor
  - setNextExecutor
```
void setNextExecutor(Executor executor)
```
    Set next executor element in execution chain
    
    Parameters:
    
    executor - Event executor for incremental execution
  - setEmitTime
```
void setEmitTime(long emitTimeOfLatestEventInTable)
```
