the class PsiProximityComparator method getProximity.

@Nullable
public static WeighingComparable<PsiElement, ProximityLocation> getProximity(final Computable<PsiElement> elementComputable, final PsiElement context, ProcessingContext processingContext) {
    PsiElement element = elementComputable.compute();
    if (element == null)
