public interface QueryResult
extends java.util.Iterator<ResultDataPoint>
```
The results of a TSDB query. It is designed to provide values in a streaming fashion, either through a producer-consumer model with next(), or an async consumer model by using onData(Consumer).
Important: Only one of the two models can be used at a time. Attempting to call next() after setting a data consumer, or viceversa, will result in an IllegalStateException.

- Method Detail
  - getPathInfo
```
java.util.List<PathInfo> getPathInfo()
```
    Information about the paths queried. Corresponds 1-to-1 with the paths passed in when the query was executed.
  - isErrored
```
boolean isErrored()
```
  - getError
```
java.lang.Exception getError()
```
  - onData
```
void onData(java.util.function.Consumer<DataPoint> consumer,
            java.util.function.BiConsumer<java.lang.Boolean,java.lang.Throwable> onComplete)
```
  - cancel
```
void cancel()
```
    Cancels the query. Will call onComplete immediately, and will no longer process values. If takeNext() is blocked, it will throw an interrupted exception.
