Method Detail

allRows

List<AnalyticsQueryRow> allRows()

Returns:

the list of all AnalyticsQueryRow, the results of the query, if successful.

rows

Iterator<AnalyticsQueryRow> rows()

Returns:

an iterator over the list of all AnalyticsQueryRow, the results of the query, if successful.

signature

Object signature()

Returns:

an object representing the signature of the results, that can be used to learn about the common structure of each row. This signature is usually a JsonObject, but could also be any JSON-valid type like a boolean scalar, JsonArray…

info

AnalyticsMetrics info()

Returns:

an object describing some metrics/info about the execution of the query.

parseSuccess

boolean parseSuccess()

Returns:

true if the query could be parsed, false if it short-circuited due to syntax/fatal error.

finalSuccess

boolean finalSuccess()

Denotes the success or failure of the query. It could fail slower than with parseSuccess(), for example if a fatal error comes up while streaming the results to the client. This method blocks until the query is over and the success can be established.

status

String status()

Returns the final status of the query. For example, a successful query will return “success” (which is equivalent to finalSuccess() returning true). Other statuses include (but are not limited to) “fatal” when fatal errors occurred and “timeout” when the query timed out on the server side but not yet on the client side. This method blocks until the query is over and the status can be established.

errors

List<JsonObject> errors()

Returns:

A list of errors or warnings encountered while executing the query.

requestId

String requestId()

Returns:

the requestId generated by the server

clientContextId

String clientContextId()

Returns:

the clientContextId that was set by the client (could be truncated to 64 bytes of UTF-8 chars)
