public class AttributeDataType

extends Enum

The enumeration AttributeRepresentation is essentially a data type for the attribute. JDM specifies three data types: integer, double, and string. Vendors may choose to augment this with other representations which include: float, date, and time.

The values defined in JDM are:

• integerType - The values of the attribute are represented as numbers in integer format.
• doubleType - The values of the attribute are represented as numbers in double precision.
• stringType - The values of the attribute are represented as strings.
