Interface TypeListener

public interface TypeListener
Listens for Guice to encounter injectable types. If a given type has its constructor injected in one situation but only its methods and fields injected in another, Guice will notify this listener once.

Useful for extra type checking, registering injection listeners, and TypeEncounter#bindInterceptor( org.elasticsearch.common.inject.matcher.Matcher, org.aopalliance.intercept.MethodInterceptor[]) binding method interceptors.
