Hinweise
The buffer manager is responsible for allocating, managing, and deleting the IDTSBuffer100 objects used by the data flow task, and the components contained by the task from a source through to the destination. It provides utility functions for registering buffer types, locating columns in a buffer, retrieving metadata about a column in a buffer, and creating private buffers that are used internally by the component that requests the private buffer.
Managed data flow component developers use the buffer manager primarily to locate columns in a PipelineBuffer that were defined in the IDTSInput100 and IDTSOutput100 objects of the component. Managed components do not interact directly with the IDTSBuffer100 objects created by the buffer manager, but instead use the managed PipelineBuffer class that marshals data between managed and native code. As such, the methods of the buffer manager that create IDTSBuffer100 objects are not used by managed component developers.
