Description copied from interface: ColumnIndexSupplier

Try to get a column 'index' of the specified type. If the index of the desired type is not available, this method will return null. If the value is non-null, the index may be used for the eventual construction of an Offset to form the basis of a Cursor (or VectorOffset and VectorCursor) which can greatly reduce the total number of rows which need to be scanned and processed. Objects returned by this method are not thread-safe.
