Package io.vertx.mutiny.ext.sql

Class SQLRowStream

  • All Implemented Interfaces:
    ReadStream<io.vertx.core.json.JsonArray>, StreamBase
    public class SQLRowStream
extends Object
implements ReadStream<io.vertx.core.json.JsonArray>
    A ReadStream of Rows from the underlying RDBMS. This class follows the ReadStream semantics and will automatically close the underlying resources if all returned rows are returned. For cases where the results are ignored before the full processing of the returned rows is complete the close method **MUST** be called in order to release underlying resources. The interface is minimal in order to support all SQL clients not just JDBC.

    NOTE: This class has been automatically generated from the original non Mutiny-ified interface using Vert.x codegen.

      • fetch

        public ReadStream<io.vertx.core.json.JsonArray> fetch​(long arg0)
        Specified by:

      • pipe

        public Pipe<io.vertx.core.json.JsonArray> pipe()
        Specified by:
        pipe in interface ReadStream<io.vertx.core.json.JsonArray>

      • pipeTo

        @CheckReturnValue
public io.smallrye.mutiny.Uni<Void> pipeTo​(WriteStream<io.vertx.core.json.JsonArray> dst)
        Specified by:
        pipeTo in interface ReadStream<io.vertx.core.json.JsonArray>

      • pipeToAndForget

        public void pipeToAndForget​(WriteStream<io.vertx.core.json.JsonArray> dst)
        Specified by:
        pipeToAndForget in interface ReadStream<io.vertx.core.json.JsonArray>

      • column

        public int column​(String name)
        Parameters:
        name - the column name
        Returns:
        the json array index

      • columns

        public List<String> columns()
        Returns:
        the list of columns names returned by the query

      • resultSetClosedHandler

        public SQLRowStream resultSetClosedHandler​(Runnable handler)
        Parameters:
        handler - called when the current result set is closed
        Returns:

      • moreResults

        public void moreResults()

      • close

        @CheckReturnValue
public io.smallrye.mutiny.Uni<Void> close()
        Closes the stream/underlying cursor(s). The actual close happens asynchronously.

        Unlike the bare Vert.x variant, this method returns a Uni. Don't forget to subscribe on it to trigger the operation.

        Returns:
        the uni firing the result of the operation when completed, or a failure if the operation failed.

      • closeAndAwait

        public Void closeAndAwait()
        Blocking variant of close().

        This method waits for the completion of the underlying asynchronous operation. If the operation completes successfully, the result is returned, otherwise the failure is thrown (potentially wrapped in a RuntimeException).

        Returns:
        the Void instance produced by the operation.

      • closeAndForget

        public void closeAndForget()
        Variant of close() that ignores the result of the operation.

        This method subscribes on the result of close(), but discards the outcome (item or failure). This method is useful to trigger the asynchronous operation from close() but you don't need to compose it with other operations.

      • toMulti

        @CheckReturnValue
public io.smallrye.mutiny.Multi<io.vertx.core.json.JsonArray> toMulti()
        Specified by:
        toMulti in interface ReadStream<io.vertx.core.json.JsonArray>

      • toBlockingIterable

        public Iterable<io.vertx.core.json.JsonArray> toBlockingIterable()

      • toBlockingStream

        public Stream<io.vertx.core.json.JsonArray> toBlockingStream()
