Type Members

  1. abstract type StreamState >: Null <: AnyRef

    The type used by this action for the state of a suspended stream.

    The type used by this action for the state of a suspended stream. A call to emitStream produces such a state which is then fed back into the next call.

  5. def andFinally[E2 <: Effect](a: DBIOAction[_, NoStream, E2]): DBIOAction[Unit, NoStream, Effect with E2]

    Run another action after this action, whether it succeeds or fails, and then return the result of the first action.

    Run another action after this action, whether it succeeds or fails, and then return the result of the first action. If the first action fails, its failure is propagated, whether the second action fails or succeeds. If the first action succeeds, a failure of the second action is propagated.

  6. def andThen[R2, S2 <: NoStream, E2 <: Effect](a: DBIOAction[R2, S2, E2]): DBIOAction[R2, S2, Effect with E2]

    Run another action after this action, if it completed successfully, and return the result of the second action.

    Run another action after this action, if it completed successfully, and return the result of the second action. If either of the two actions fails, the resulting action also fails.

  8. def asTry: DBIOAction[Try[Unit], NoStream, Effect]

    Convert a successful result v of this action into a successful result Success(v) and a failure t into a successful result Failure(t).

    Convert a successful result v of this action into a successful result Success(v) and a failure t into a successful result Failure(t). This is the most generic combinator that can be used for error recovery. If possible, use andFinally or cleanUp instead, because those combinators, unlike asTry, support streaming.

  9. def cancelStream(context: StreamingContext, state: StreamState): Unit

    Dispose of a StreamState when a streaming action is cancelled.

    Dispose of a StreamState when a streaming action is cancelled. Whenever emitStream returns null or throws an Exception, it needs to dispose of the state itself. This method will not be called in these cases.

  10. def cleanUp[E2 <: Effect](f: (Option[Throwable]) => DBIOAction[_, NoStream, E2], keepFailure: Boolean = true)(implicit executor: ExecutionContext): DBIOAction[Unit, NoStream, Effect with E2]

    Run another action after this action, whether it succeeds or fails, in order to clean up or transform an error produced by this action.

    Run another action after this action, whether it succeeds or fails, in order to clean up or transform an error produced by this action. The clean-up action is computed from the failure of this action, wrapped in Some, or None if this action succeeded.

    keepFailure

    If this action returns successfully, the resulting action also returns successfully unless the clean-up action fails. If this action fails and keepFailure is set to true (the default), the resulting action fails with the same error, no matter whether the clean-up action succeeds or fails. If keepFailure is set to false, an error from the clean-up action will override the error from this action.

    Run this action synchronously and emit results to the context.

    Run this action synchronously and emit results to the context. This methods may throw an Exception to indicate a failure.

    limit

    The maximum number of results to emit, or Long.MaxValue for no limit.

    state

    The state returned by a previous invocation of this method, or null if a new stream should be produced.

    returns

    A stream state if there are potentially more results available, or null if the stream is finished.
