@Convert

Use @Convert to specify that a named converter should be used with the corresponding mapped attribute.

Annotation Elements

Table 2-14 describes this annotation's elements.

Usage

The @Convert has the following reserved names:

• serialized – Places the org.eclipse.persistence.mappings.converters.SerializedObjectConverter on the associated mapping.

• class-instance – Uses an ClassInstanceConverter on the associated mapping. When using a ClassInstanceConverter, the database representation is a String representing the Class name and the object-model representation is an instance of that class built with a no-args constructor

• none – Does not place a converter on the associated mapping.

Examples

Example 2-31 shows how to use the @Convert annotation to define the gender field.

@Entity
 @Table(name="EMPLOYEE")
 @Converter(
     name="genderConverter",
         converterClass=org.myorg.converters.GenderConverter.class
 )
 public class Employee implements Serializable{
     ...
     @Basic
     @Convert("genderConverter")
     public String getGender() {
         return gender;
     }
     ...
 }
