Streamable (Java EE 5)

Streamable 接口提供组件在 Record 实例中设置的资源适配器的数据视图。

组件不能直接使用 Streamable 接口。而是通过资源适配器实现使用。组件使用 Record 或任何派生的接口来管理记录。

Streamable interface enables a resource adapter to extract data from an input Record or set data into an output Record as a stream of bytes.

The Streamable interface provides a resource adapter's view of the data that has been set in a Record instance by a component.

The Streamable interface is not directly used by a component. It is used by a resource adapter implementation. A component uses Record or any derived interfaces to manage records.
