Returns:

the total number of results selected by the engine before restriction through LIMIT clause.

resultCount

public int resultCount()

Returns:

The total number of objects in the results.

resultSize

public long resultSize()

Returns:

The total number of bytes in the results.

mutationCount

public int mutationCount()

Returns:

The number of mutations that were made during the request.

errorCount

public int errorCount()

Returns:
