All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.util.Map<ConcurrentScannerDocFetcherTask.TaskState,java.lang.Long>`	`countByState()`	State: Get the count for each `ConcurrentScannerDocFetcherTask.TaskState`.
`java.util.List<ConcurrentScannerDocFetcherTask.TaskInfo>`	`getFetcherStates(java.util.List<java.lang.String> uids)`	Get detailed `ConcurrentScannerDocFetcherTask.TaskInfo` information for this list of task uuid
`java.util.stream.Stream<java.lang.String>`	`getList(ConcurrentScannerDocFetcherTask.TaskState state)`	Details: Get a stream of task UUID for this `ConcurrentScannerDocFetcherTask.TaskState` state.
`java.util.Map<ConcurrentScannerTaskExecuter.ConcurrentExecutionMetrics,ConcurrentScannerPerformanceAlert>`	`getPerformanceMetrics()`	Throughput: Returns the frequency of events over a period of time (e.g over the last 5 minutes).
`boolean`	`scannerIsDoneQueuing()`	Returns true if the scanner told the document fetcher that it's done queuing tasks by calling doneQueuing or by calling stop

- Method Detail
  - scannerIsDoneQueuing
```
boolean scannerIsDoneQueuing()
```
    Returns true if the scanner told the document fetcher that it's done queuing tasks by calling doneQueuing or by calling stop
    
    Returns:
  - countByState
```
java.util.Map<ConcurrentScannerDocFetcherTask.TaskState,java.lang.Long> countByState()
```
    State: Get the count for each ConcurrentScannerDocFetcherTask.TaskState.
    
    Returns:
    
    state count map
  - getPerformanceMetrics
```
java.util.Map<ConcurrentScannerTaskExecuter.ConcurrentExecutionMetrics,ConcurrentScannerPerformanceAlert> getPerformanceMetrics()
```
    Throughput: Returns the frequency of events over a period of time (e.g over the last 5 minutes). Low queuing frequency, for example, could indicate the need to add more work threads.
    
    Returns:
    
    frequency map
  - getList
```
java.util.stream.Stream<java.lang.String> getList(ConcurrentScannerDocFetcherTask.TaskState state)
```
    Details: Get a stream of task UUID for this ConcurrentScannerDocFetcherTask.TaskState state.
    
    Parameters:
    
    state -
    
    Returns:
    
    task uuid stream
  - getFetcherStates
```
java.util.List<ConcurrentScannerDocFetcherTask.TaskInfo> getFetcherStates(java.util.List<java.lang.String> uids)
```
    Get detailed ConcurrentScannerDocFetcherTask.TaskInfo information for this list of task uuid
    
    Parameters:
    
    uids -
    
    Returns:
    
    task details
