CallBack Methods and Inline Methods?

[Chaminda Amarasinghe]

Can somebody explain what is CallBack method and what is Inline method?

Why HFSJ says (page no 696)
1) The destroy() methoid of filter in always a container callback method

2) The doFilter method of a filter is a callback and an inline method?

Thanks

2) The doFilter method of a filter is a callback and an inline method?

Because doFilter is both in the Filter class and the FilterChain class. The former being a container callback, the later being a so-called "inline" method because you call it implicitly within a filter.

I think that you'll then understand why destroy() is only a callback.
