Parametri

outputs
The number of elements in the outputIDs and buffers arrays.

outputIDs
An array of IDTSOutput90 ID's.

buffers
An array of PipelineBuffer objects.

Osservazioni

The number of elements in the outputIDs and buffers array is determined by the number of IDTSOutput90 objects in the IDTSOutputCollection90 collection of the component connected to an IDTSPath90 object.

Each element in the outputIDs array has a PipelineBuffer at the same index in the buffers array.

Rows are added to the PipelineBuffer by calling the AddRow method, and when finished, the SetEndOfRowset method is called to notify the data flow task that the component is finished adding rows.

PrimeOutput is called for components whose SynchronousInputID property is set to zero.
