All Implemented Interfaces:
Serializable, Comparable<DBFDataType>, java.lang.constant.Constable
public enum DBFDataType extends Enum<DBFDataType>
Defines the possible data types for fields within a DBF file.

The types cover standard dBase III+ formats as well as extensions found in later versions like Visual FoxPro (VFP) and dBase Level 7.
