Class DefaultCellIterator

java.lang.Object
  org.knime.core.data.def.DefaultCellIterator

All Implemented Interfaces:

Iterator<DataCell>

public class DefaultCellIterator
extends Object
implements Iterator<DataCell>

Default implementation of an iterator over the DataCells of a DataRow. It uses the getNumCells() and getCell(int) methods of the underlying row to return the cells. Hence, it starts at the cell of the column with index 0 and then sequentially returns the cells up to the last cell (of the column with the highest index) in the row.

The iterator doesn't support removal of datacells, an invocation of the method remove() will end up with an exception.
