H init( ) Methods for Oracle Multimedia Object Types

This appendix presents reference information about the init( ) methods for these four Oracle Multimedia object types:

In this appendix, references to ORDxxx objects represent these four Oracle Multimedia object types.

Note:

In Oracle Database 11g Release 2 (11.2), Oracle introduces new constructor functions to construct ORDxxx objects from BLOBs and other sources. The init( ) methods will continue to be available in Oracle Database 11g Release 2. 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 Chapter 3, Chapter 4, Chapter 5, and Chapter 6 for information about the new constructor functions for ORDxxx objects.

This appendix describes these methods:

init( ) for ORDAudio

Format

init( ) RETURN ORDAudio;

Description

Initializes instances of the ORDAudio object type.

Parameters

None.

Pragmas

Exceptions

None.

Usage Notes

This constructor is a static method that initializes all the ORDAudio attributes to NULL with these exceptions:

  • source.updateTime is set to SYSDATE

  • source.local is set to 1 (local)

  • source.localData is set to empty_blob

Examples

None.

init( ) for ORDDoc

Format

init( ) RETURN ORDDoc;

Description

Initializes instances of the ORDDoc object type.

Parameters

None.

Pragmas

None.

Exceptions

None.

Usage Notes

This constructor is a static method that initializes all the ORDDoc attributes to NULL with these exceptions:

  • source.updateTime is set to SYSDATE

  • source.local is set to 1 (local)

  • source.localData is set to empty_blob

Examples

None.

init( ) for ORDImage

Format

init( ) RETURN ORDImage;

Description

Exceptions

None.

Usage Notes

This constructor is a static method that initializes all the ORDAudio attributes to NULL with these exceptions:

  • source.updateTime is set to SYSDATE

  • source.local is set to 0

  • source.localData is set to empty_blob

  • source.srcType is set to the input value

  • source.srcLocation is set to the input value

  • source.srcName is set to the input value

Examples

None.

init(srcType,srcLocation,srcName) for ORDDoc

Format
