Class OrdMediaUtil

java.lang.Object

oracle.ord.im.OrdMediaUtil

Deprecated.

The OrdMediaUtil class allows other Oracle Multimedia Java classes to connect to Oracle Database and access data in tables that contain columns of Oracle Multimedia object types. This class includes methods for downloading and uploading data.

Users of this class should be familiar with Oracle Multimedia Reference.

Prerequisites

Before running OrdMediaUtil methods, the following operations must have already been performed:

• A connection has been made to a table that contains columns of the appropriate Oracle Multimedia object types (OrdAudio, OrdDoc, OrdImage, OrdVideo, and so on).
• Local Oracle Multimedia objects have been created and populated with data.

For examples of making a connection and populating a local object, see Oracle Multimedia User's Guide.

public class OrdMediaUtil
extends java.lang.Object
