public class Attribute

extends MiningObject

An instance of Attribute maps to a column with a name and datatype. The attribute corresponds to a column in a database table. When assigned to a column, the column must have a compatible data type; if the data type is not compatible, a runtime exception is likely.

Class Attribute is also used as a common superclass for objects requiring a name and datatype, such as MiningAttribute.
