IBDA_NullTransform Interface

The IBDA_NullTransform interface is implemented on all BDA device filters. The Network Provider filter calls these methods to instruct the filter to either pass data through without modifying it, or else to perform its particular transformation on the data.

In addition to the methods inherited from IUnknown, the IBDA_NullTransform interface exposes the following methods.

Method Description
Start Restarts the transforms on data flowing through the control node.
Stop Stops the transforms on data flowing through the control node.

Requirements
