Package com.tableau.hyperapi

## Class Result

- java.lang.Object
- - com.tableau.hyperapi.Result

- All Implemented Interfaces:
    `java.lang.AutoCloseable`

      public final class Result
      extends java.lang.Object
      implements java.lang.AutoCloseable

  A query result.

  Executing a query returns a result (see `Connection.executeQuery(String)`). The rows of a result can be iterated via `nextRow()`. The value of each column can be accessed via a type-specific getter such as `getInt(int)`.

  This is an `AutoCloseable` class since it maintains native resources. The `close()` method must always be called when the result is no longer needed. The best way to guarantee this is to use a try-with-resources block.
