Examples of jfun.yan.Container.verifyComponent()

jfun.yan.Container.verifyComponent()
Verifies that a Component is valid using the current container in resolving dependency. @param cc the component to verify. @return the type of the component. @throws AmbiguousComponentResolutionException if ambiguity happens. @throws CyclicDependencyException if cyclic dependency is detected. @throws UnsatisfiedComponentException if some requirement of a component cannot be satisfied. @throws YanException for any other exception.
