### Question:
BeanPath extends SimpleExpression<T> implements Path<T> { public <B extends T> BooleanExpression instanceOf(Class<B> type) { return Expressions.booleanOperation(Ops.INSTANCE_OF, pathMixin, ConstantImpl.create(type)); } BeanPath(Class<? extends T> type, String variable);  BeanPath(Class<? extends T> type, Path<?> parent,  String property);  BeanPath(Class<? extends T> type, PathMetadata metadata);  BeanPath(Class<? extends T> type, PathMetadata metadata, @Nullable PathInits inits); @Override final R accept(Visitor<R,C> v, C context); @SuppressWarnings("unchecked") U as(Class<U> clazz); @Override PathMetadata getMetadata(); @Override Path<?> getRoot(); BooleanExpression instanceOf(Class<B> type); @SuppressWarnings({ "unchecked", "rawtypes" }) BooleanExpression instanceOfAny(Class... types); @Override AnnotatedElement getAnnotatedElement();  }### Answer:
@Test public void instanceOf() { assertNotNull(beanPath.instanceOf(BeanPathTest.class)); }
