Reads a single record for the transform output, if there are any. If there are no more output records, it returns .
The base class implementation calls Read on all the input readers and return if at least one of these operations is successful.
Transforms that process a single record at one time do not need to override the base class implementation.
Transforms that process multiple records at one time need to override the base class implementation by retrieving the necessary input data and also performing output record processing.
If the Read operation is successful, the transform is responsible for providing corresponding data values on subsequent FetchElementValue calls.
