Annotation Type TypeConverter

@Retention(value=RUNTIME)
@Target(value=TYPE)
public @interface TypeConverter

Annotation that indicates the target class is a type converter class. A type converter class should have:

• Non-parameter constructor
• A public void init(Map<String, String> props) method
• One and only one pair of public methods convertToTarget and convertToSource that meet the following conditions:
1. Has return value and a parameter
2. The return value and parameter of the two methods are matching

Code example:

The following code show how to implements a converter between String and boolean.

  @TypeConverter
  public class StringBooleanConverter {
 
    protected String trueExp;
    protected String falseExp;
 
    public void init(Map props) {
      this.trueExp = props.get("cobol_bool_true"); 
      this.falseExp = props.get("cobol_bool_false"); 
    }
 
    public synchronized boolean convertToTarget(String source) {
      return trueExp.equals(source);
    }
 
    public synchronized String convertToSource(boolean target) {
      return target ? trueExp : falseExp;
   }
 }
