io.vertx.rxjava.sqlclient

## Class Cursor

- java.lang.Object
- - io.vertx.rxjava.sqlclient.Cursor

-     public class Cursor
      extends Object

  A cursor that reads progressively rows from the database, it is useful for reading very large result sets.

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

  - ### Method Summary

    All Methods Static Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `void` | `close()` Release the cursor.
    `void` | `close(Handler<AsyncResult<Void>> completionHandler)` Like `close()` but with a `completionHandler` called when the cursor has been released.
    `boolean` | `equals(Object o)`
    `Cursor` | `getDelegate()`
    `int` | `hashCode()`
    `boolean` | `hasMore()` Returns `true` when the cursor has results in progress and the `read(int, io.vertx.core.Handler<io.vertx.core.AsyncResult<io.vertx.rxjava.sqlclient.RowSet<io.vertx.rxjava.sqlclient.Row>>>)` should be called to retrieve them.
    `boolean` | `isClosed()`
    `static Cursor` | `newInstance(Cursor arg)`
    `void` | `read(int count, Handler<AsyncResult<RowSet<Row>>> handler)` Read rows from the cursor, the result is provided asynchronously to the `handler`.
    `Single<Void>` | `rxClose()` Like `close()` but with a `completionHandler` called when the cursor has been released.
    `Single<RowSet<Row>>` | `rxRead(int count)` Read rows from the cursor, the result is provided asynchronously to the `handler`.
    `String` | `toString()`

      Read rows from the cursor, the result is provided asynchronously to the `handler`.
      Parameters:
        `count` - the amount of rows to read
        `handler` - the handler for the result

      Returns:

    - #### hasMore

          public boolean hasMore()

      Returns `true` when the cursor has results in progress and the `read(int, io.vertx.core.Handler<io.vertx.core.AsyncResult<io.vertx.rxjava.sqlclient.RowSet<io.vertx.rxjava.sqlclient.Row>>>)` should be called to retrieve them.
      Returns:
        whether the cursor has more results,

    - #### close

          public void close()

      Release the cursor.

    - #### close

          public void close(Handler<AsyncResult<Void>> completionHandler)

      Like `close()` but with a `completionHandler` called when the cursor has been released.
      Parameters:
        `completionHandler` -

    - #### rxClose

          public Single<Void> rxClose()

      Like `close()` but with a `completionHandler` called when the cursor has been released.
      Returns:

    - #### isClosed

          public boolean isClosed()

      Returns:
        whether the cursor is closed
