public interface BoundedValue extends DataValue
DataCellshould implement this interface to indicate that its objects can be reasonably ordered. "Reasonably" refers here to:
DataTypeis compatible with this interface is desirable (see below).
This interface should be used, for instance for numeric data cells such as
IntCell, it should also be used for ordinal
columns (so far there is no ordinal column type in KNIME but if there were it
would implement this interface). On the other hand, types such as
ComplexNumberCell do not implement this
interface as they do not define a meaningful comparator.
Although not strictly enforced, a
DataColumnSpec will have non-null
lower and upper bounds in its
DataColumnDomain if the column's
DataType is compatible to this interface. It will typically not have
bounds for other types.
This interface does not specify any methods. It is only used to indicate the above outlined property.
