  • Method Details

    • hasInfo

      boolean hasInfo()
      
 The currently available results.

 If "flight_descriptor" is not specified, the query is complete
 and "info" specifies all results. Otherwise, "info" contains
 partial query results.

 Note that each PollInfo response contains a complete
 FlightInfo (not just the delta between the previous and current
 FlightInfo).

 Subsequent PollInfo responses may only append new endpoints to
 info.

 Clients can begin fetching results via DoGet(Ticket) with the
 ticket in the info before the query is
 completed. FlightInfo.ordered is also valid.
      .arrow.flight.protocol.FlightInfo info = 1;
      Returns:
      Whether the info field is set.

    • getInfo

      Flight.FlightInfo getInfo()
      
 The currently available results.

 If "flight_descriptor" is not specified, the query is complete
 and "info" specifies all results. Otherwise, "info" contains
 partial query results.

 Note that each PollInfo response contains a complete
 FlightInfo (not just the delta between the previous and current
 FlightInfo).

 Subsequent PollInfo responses may only append new endpoints to
 info.

      .arrow.flight.protocol.FlightInfo info = 1;
      Returns:
      The info.

    • hasFlightDescriptor

      boolean hasFlightDescriptor()
      
 The descriptor the client should use on the next try.
 If unset, the query is complete.
      .arrow.flight.protocol.FlightDescriptor flight_descriptor = 2;
      Returns:
      Whether the flightDescriptor field is set.

    • getFlightDescriptor

      Flight.FlightDescriptor getFlightDescriptor()
      
 The descriptor the client should use on the next try.
 If unset, the query is complete.
      .arrow.flight.protocol.FlightDescriptor flight_descriptor = 2;
      Returns:
      The flightDescriptor.

    • getFlightDescriptorOrBuilder

      Flight.FlightDescriptorOrBuilder getFlightDescriptorOrBuilder()
      
 The descriptor the client should use on the next try.
 If unset, the query is complete.
      .arrow.flight.protocol.FlightDescriptor flight_descriptor = 2;

    • hasProgress

      boolean hasProgress()
      
 Query progress. If known, must be in [0.0, 1.0] but need not be
 monotonic or nondecreasing. If unknown, do not set.
      optional double progress = 3;
      Returns:
      Whether the progress field is set.

    • getProgress

      double getProgress()
      
 Query progress. If known, must be in [0.0, 1.0] but need not be
 monotonic or nondecreasing. If unknown, do not set.
      optional double progress = 3;
      Returns:
      The progress.

    • hasExpirationTime

      boolean hasExpirationTime()
      
 Expiration time for this request. After this passes, the server
 might not accept the retry descriptor anymore (and the query may
 be cancelled). This may be updated on a call to PollFlightInfo.
      .google.protobuf.Timestamp expiration_time = 4;
      Returns:
      Whether the expirationTime field is set.

    • getExpirationTime

      com.google.protobuf.Timestamp getExpirationTime()
      
 Expiration time for this request. After this passes, the server
 might not accept the retry descriptor anymore (and the query may
 be cancelled). This may be updated on a call to PollFlightInfo.
      .google.protobuf.Timestamp expiration_time = 4;
      Returns:
      The expirationTime.

    • getExpirationTimeOrBuilder

      com.google.protobuf.TimestampOrBuilder getExpirationTimeOrBuilder()
      
 Expiration time for this request. After this passes, the server
 might not accept the retry descriptor anymore (and the query may
 be cancelled). This may be updated on a call to PollFlightInfo.
      .google.protobuf.Timestamp expiration_time = 4;
