Examples with Nonbinding javax.enterprise.util.Nonbinding used on opensource projects

Example 1 with Nonbinding

use of javax.enterprise.util.Nonbinding in project deltaspike by apache.

the class ReflectionUtils method calculateHashCodeOfAnnotation.

public static int calculateHashCodeOfAnnotation(Annotation annotation, boolean skipNonbindingMembers) {
    Class annotationClass = annotation.annotationType();
    // the hashCode of an Annotation is calculated solely via the hashCodes
    // of it's members. If there are no members, it is 0.
    // thus we first need to get the annotation-class hashCode
    int hashCode = calculateHashCodeOfType(annotationClass);
    // and now add the hashCode of all it's Nonbinding members
    // the following algorithm is defined by the Annotation class definition
    // see the JavaDoc for Annotation!
    // we only change it so far that we skip evaluating @Nonbinding members
    final Method[] members = annotationClass.getDeclaredMethods();
    for (Method member : members) {
        if (skipNonbindingMembers && member.isAnnotationPresent(Nonbinding.class)) {
            // ignore the non binding
            continue;
