Class BinaryCodedField

java.lang.Object

db.Field

db.BinaryField

db.BinaryCodedField

All Implemented Interfaces:

java.lang.Comparable<Field>

public class BinaryCodedField
extends BinaryField

Allows various non-database supported data types to be encoded within a BinaryField which may be stored within the database.

Although the BinaryField stores a byte array, this type is supported by this class so that the use of a BinaryField within a table can always relate to this class and still support a byte array.
