- Method Detail
  - startWaitingForResources
```
void startWaitingForResources()
```
  - fail
```
void fail(Throwable cause)
```
  - addStateChangeListener
```
void addStateChangeListener(StateMachine.StateChangeListener<QueryState> stateChangeListener)
```
    Listener is always notified asynchronously using a dedicated notification thread pool so, care should be taken to avoid leaking this when adding a listener in a constructor. Additionally, it is possible notifications are observed out of order due to the asynchronous execution.
  - getSession
```
Session getSession()
```
  - getUserMemoryReservation
```
io.airlift.units.DataSize getUserMemoryReservation()
```
  - getTotalMemoryReservation
```
io.airlift.units.DataSize getTotalMemoryReservation()
```
  - getTotalCpuTime
```
io.airlift.units.Duration getTotalCpuTime()
```
  - getBasicQueryInfo
```
BasicQueryInfo getBasicQueryInfo()
```
  - getFullQueryInfo
```
QueryInfo getFullQueryInfo()
```
  - getState
```
QueryState getState()
```
  - isDone
```
boolean isDone()
```
  - getErrorCode
```
Optional<ErrorCode> getErrorCode()
```
    Returns:
    
    Returns non-empty value iff error has occurred and query failed state is visible.
