func1().func2() what is this technique called?

Question

In spring security I see functions connected by and() and .(dot). So what is this technique? I've read through it before. But now I forgot, can anyone tell me a name so I can learn about it?

http
  .authorizeRequests()
    .antMatchers("/", "/home").permitAll()
    .anyRequest().authenticated()
    .and()
  .formLogin()
    .loginPage("/login")
    .permitAll()
    .and()
  .logout()
    .permitAll();

It's called "chaining". But more to the point, it's an example of [Fluent Style](https://en.wikipedia.org/wiki/Fluent_interface) — paulsm4, Aug 19 '21 at 16:58
It's Method Chaining aka Fluent API. Spring Security is a lousy example of it though - that API is _really_ bad and unintuitive. The fact that you had to manually format your code adding extra indentation is a good indication of bad design. — Stanislav Bashkyrtsev, Aug 19 '21 at 17:05

That is a very vague description, but i think you are looking for the term method chaining.
