Method Detail

annotationType

public Class<? extends Annotation> annotationType()

Implemented for compatibility reasons with other cdi-api jar's. See OWB-802.

Specified by:

annotationType in interface Annotation

Overrides:

annotationType in class javax.enterprise.util.AnnotationLiteral<T extends Annotation>

hashCode

public int hashCode()

Implemented for performance reasons. This is needed because an Annotation always returns 0 as hashCode if there is no method in it. Contrary to this the generic AnnotationLiteral.hashCode() always does search for methods via reflection and only then returns 0. Not very well performing ...

Specified by:

hashCode in interface Annotation

Overrides:

hashCode in class javax.enterprise.util.AnnotationLiteral<T extends Annotation>

Returns:

always 0

equals

public boolean equals(Object other)

Just checks whether the 2 classes have the same annotationType. We do not need to dynamically evaluate the member values via reflection as there are no members in this annotation at all.

Specified by:

equals in interface Annotation

Overrides:

equals in class javax.enterprise.util.AnnotationLiteral<T extends Annotation>
