All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`accumulateRowStream(java.util.stream.Stream<com.datastax.driver.core.Row> rowStream)`	Processes each row and updates the internal state of the instance.

- Method Detail
  - accumulateRowStream
```
void accumulateRowStream(java.util.stream.Stream<com.datastax.driver.core.Row> rowStream)
```
    Processes each row and updates the internal state of the instance. After each invocation of this method calling result should return the accumulated result of rows processed up to that moment. Implementations should not block during processing of the passed stream as that would prevent the thread from doing other work. If invoked concurrently with either accumulateRowStream or result the behaviour is not defined.
    
    Parameters:
    
    rowStream - of available rows without blocking
  - result
```
R result()
```
    Should be called after all intended streams are processed. Will return the current state of the accumulator without knowing if it is the end result. If invoked concurrently with eitheraccumulateRowStream or result the behaviour is not defined.
    
    Returns:
    
    accumulated result
