public void export (byte[ ] [ ] ctx, String srcType, String srcLocation, String srcName)
Exports the data from the BLOB specified by the localData attribute. This method calls the corresponding export( ) method in the database to export the audio data to a location specified by the srcType, srcLocation, and srcName parameters.
Not all source plug-ins support this method. Only the "file" source type is natively supported.
This method will work only if you are running Oracle release 8.1.7 or later.
The remainder of this description describes the use of the export( ) method and the Oracle-supplied "file" source plug-in. User-written plug-ins will behave differently.
The export( ) method implemented by the "file" source plug-in copies, but does not modify, the audio data stored in the database BLOB specified by the localData attribute.
After exporting the audio data, all the audio property attributes remain unchanged. However, the srcType, srcLocation, and srcName attributes are updated with values of the srcType, srcLocation, and srcName parameters passed to the export( ) method. After calling the export( ) method, if you no longer intend to manage the audio data within the database, call the clearLocal( ) method to indicate that the audio data is stored outside the database, and call the deleteContent( ) method to delete the audio data stored in the database BLOB.

This exception is thrown if an error occurs executing the corresponding export( ) method in the database.
