Method Detail

getSourceIndex

public int getSourceIndex()

Description copied from interface: ITuple

The index of the source from which the tuple was read. This is zero (0) if there is only a single source, e.g., a BTree or IndexSegment. When reading on a FusedView this is the index of the element of the view which reported the tuple.
