DefaultN1qlQueryResult

public DefaultN1qlQueryResult(List<AsyncN1qlQueryRow> rows,
                              Object signature,
                              N1qlMetrics info,
                              List<JsonObject> errors,
                              String finalStatus,
                              Boolean finalSuccess,
                              boolean parseSuccess,

                              String clientContextId)

Create a default blocking representation of a query result.

Parameters:

rows - the list of rows.

signature - the signature for rows.

info - the metrics.

errors - the list of errors and warnings.

finalStatus - the definitive (but potentially delayed) status of the query.

finalSuccess - the definitive (but potentially delayed) success of the query.

parseSuccess - the intermediate result of the query

Method Detail

allRows

public List<N1qlQueryRow> allRows()

Specified by:

allRows in interface N1qlQueryResult

Returns:

the list of all N1qlQueryRow, the results of the query, if successful.

rows

public Iterator<N1qlQueryRow> rows()

Specified by:

rows in interface N1qlQueryResult

Returns:

an iterator over the list of all N1qlQueryRow, the results of the query, if successful.

signature

public Object signature()

Specified by:

signature in interface N1qlQueryResult

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

public N1qlMetrics info()

Specified by:

info in interface N1qlQueryResult

Returns:

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

parseSuccess

public boolean parseSuccess()

Specified by:

parseSuccess in interface N1qlQueryResult

Returns:

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

errors

public List<JsonObject> errors()

Specified by:

errors in interface N1qlQueryResult

Returns:

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

finalSuccess

public boolean finalSuccess()

Description copied from interface: N1qlQueryResult

Denotes the success or failure of the query. It could fail slower than with N1qlQueryResult.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.

Specified by:

finalSuccess in interface N1qlQueryResult

status

public String status()

Description copied from interface: N1qlQueryResult

Returns the final status of the query. For example, a successful query will return “success” (which is equivalent to N1qlQueryResult.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.

Specified by:

status in interface N1qlQueryResult

iterator

public Iterator<N1qlQueryRow> iterator()

Specified by:

iterator in interface Iterable<N1qlQueryRow>

requestId

public String requestId()

Specified by:

requestId in interface N1qlQueryResult

Returns:

the requestId generated by the server

clientContextId

public String clientContextId()

Specified by:

clientContextId in interface N1qlQueryResult

Returns:

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