/** 
 *  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.
