H init( ) Methods for Oracle Multimedia Object Types

The initialization of Oracle Multimedia object types ORDAudio, ORDDoc, ORDImage and ORDVideo is accomplished through init() methods. References to ORDxxx objects represent these four Oracle Multimedia object types.

Note:

In Oracle Database 11g Release 2 (11.2), Oracle introduced new constructor functions to construct ORDxxx objects from BLOBs and other sources. The init( ) methods continue to be available in the current release. However, Oracle recommends writing new applications to use the new constructor functions. Oracle also recommends migrating existing applications from the init( ) methods to the new constructor functions at your earliest convenience.

See Oracle Multimedia ORDAudio Object Type , Oracle Multimedia ORDDoc Object Type , Oracle Multimedia ORDImage Object Type , and Oracle Multimedia ORDVideo Object Type for information about the new constructor functions for ORDxxx objects.
