Annotation Interface Classifier

@Documented
@Retention(RUNTIME)
@Target(TYPE)
public @interface Classifier

An annotation specifying the stereotype (abstract, datatype, union, etc.) of an interface. The UML class diagrams in ISO/OGC specifications declare some members as abstract, meaning that instances of those interfaces are expected to implement one of their sub-interfaces. While there is nothing like "abstract interface" and "concrete interface" in the Java language, we nevertheless communicate ISO/OGC intent using this annotation.

Implementations are not required to represent "abstract interfaces" by Java abstract classes. This annotation is provided merely for informative purpose for testing tools, implementations based on Java reflection, or widgets among other usages.

If this annotation is not present, then the default value is Stereotype.TYPE.

Since:

3.1
