def
replaceListDataColumnAsView(listCol: ColumnView, newDataCol: ColumnView): ColumnView
Replace the data column in a LIST column.
Replace the data column in a LIST column. This will keep the same offsets and validity of the listColumn. This returns a view so it is the responsibility of the caller to keep both listCol and newDataCol alive longer than the returned ColumnView.
- listCol
the list column to use as a template
- newDataCol
the new data column.
- returns
a new ColumnView.
- Exceptions thrown
scala.IllegalArgumentExceptionif data column does not match the original data column in size.
