Annotation Type Qualifier

@Target(value=ANNOTATION_TYPE)
 @Retention(value=CLASS)
public @interface Qualifier

Declares an annotation type to be a qualifier. Qualifier annotations allow unambiguously identify a suitable mapping method in case several methods qualify to map a bean property, iterable element etc.

For more info see:

• Mapping.qualifiedBy()
• BeanMapping.qualifiedBy()
• IterableMapping.qualifiedBy()
• MapMapping.keyQualifiedBy()
• MapMapping.valueQualifiedBy()

Example:

 @Qualifier
 @Target(ElementType.METHOD)
 @Retention(RetentionPolicy.CLASS)
 public @interface EnglishToGerman {
 }
 

NOTE: Qualifiers should have RetentionPolicy.CLASS.
