TABSBlobStream.Destroy
TABSBlobStream

Top

Destroys an instance of TABSBlobStream.

destructor Destroy; override;

Description
Do not call Destroy directly in an application. Instead call Free. Free verifies that the TABSBlobStream object is not nil and only then calls Destroy. Destroy the TABSBlobStream object when it is no longer needed for reading from or writing to the BLOB field.

Destroy triggers an OnDataChange event if the BLOB stream was used to overwrite or modify the data in the field. Destroy then frees any buffers that were allocated to handle the data.

Note: A TABSBlobStream object should always be destroyed before navigating to a new record. Create a new instance of TABSBlobStream for the new record.
