Value Members

  1. val bufferNext: Boolean
  2. def cancel(): Unit
    Definition Classes
    BasicStreamingActionContext → Subscription
  3. def cancelled: Boolean

    Whether the stream has been cancelled by the Subscriber

    Whether the stream has been cancelled by the Subscriber

  4. def connection: Connection

    The current JDBC Connection

    The current JDBC Connection

  5. def delivered(num: Long): Long

    Indicate that the specified number of elements has been delivered.

    Indicate that the specified number of elements has been delivered. Returns the remaining demand. This is an atomic operation. It must only be called from the synchronous action context which performs the streaming.

    Definition Classes
    BasicStreamingActionContext
  6. def demandBatch: Long

    Get the current demand that has not yet been marked as delivered and mark it as being in the current batch.

    Get the current demand that has not yet been marked as delivered and mark it as being in the current batch. When this value is negative, the initial streaming action is still running and the real demand can be computed by subtracting Long.MinValue from the returned value.

    BasicStreamingActionContext
  7. def emit(v: Any): Unit

    Emit a single result of the stream.

    Emit a single result of the stream. Any Exception thrown by this method should be passed on to the caller.

  8. final def isPinned: Boolean

    Check if the session is pinned.

    Check if the session is pinned. May only be called from a synchronous action context.

    Definition Classes
    ActionContext
  9. final def pin: Unit

    Pin the current session.

    Pin the current session. Multiple calls to pin may be nested. The same number of calls to unpin is required in order to mark the session as not pinned anymore. A pinned session will not be released at the end of a primitive database action. Instead, the same pinned session is passed to all subsequent actions until it is unpinned. Note that pinning does not force an actual database connection to be opened. This still happens on demand. May only be called from a synchronous action context.

  15. val streamingResultPromise: Promise[Null]

    The Promise to complete when streaming has finished.

    Finish the stream with onComplete if it is not finished yet.

    Finish the stream with onComplete if it is not finished yet. May only be called from a synchronous action context.

  18. def tryOnError(t: Throwable): Unit

    Finish the stream with onError if it is not finished yet.

    Finish the stream with onError if it is not finished yet. May only be called from a synchronous action context.
