Description
Frees an instance of TClientBlobStream.
Do not call Destroy directly in an application. Instead call Free. Free verifies that the TBlobStream object is not nil and only then calls Destroy.
Destroy the TClientBlobStream object by calling Free when it is no longer needed for reading from or writing to the BLOB field. Client blob streams should be destroyed when the client dataset changes the current record
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.
