question: public static Set < AnnotationMirror > glbOfBounds ( final AnnotatedIntersectionType isect , final QualifierHierarchy qualifierHierarchy ) { Set < AnnotationMirror > result = AnnotationUtils . createAnnotationSet ( ) ; for ( final AnnotationMirror top : qualifierHierarchy . getTopAnnotations ( ) ) { final AnnotationMirror glbAnno = glbOfBoundsInHierarchy ( isect , top , qualifierHierarchy ) ; if ( glbAnno != null ) { result . add ( glbAnno ) ; } } return result ; }
target:  Get's the lowest primary annotation of all bounds in the intersection
