BeanLocator is the core RSF interface which "locates" a bean in its immediate container (given a single path component):

public interface BeanLocator {
  public Object locateBean(String path);
}

Any bean found implementing BeanLocator (or indeed java.util.Map) will be navigable via RSF EL to the next path component by means of the locateBean (or get()) method, in addition to support for Java beans style paths mapping to properties via introspection (and of course Peas).

Other pages relevant to BeanLocator are OLI for a tour of RSF's One Line Interfaces, and OTP for the use of BeanLocator in the wider context of RSF's ORM idiom.
