属性值
The number of columns in the PipelineBuffer.
备注
Most of the time, there are more columns in a PipelineBuffer than are in the input or output of a component. Because of this, developers should not expect to locate a column in a buffer row by using its index in the collection. Instead, the FindColumnByLineageID method of the BufferManager should be called, which returns the ___location of the input or output column in the buffer row. This value returned from this function contains the ___location of the column in the buffer.
