Examples of jfun.yan.Container.verify()

jfun.yan.Container.verify()
Verifies the components in this container. Dependencies are resolved in the current container. @throws AmbiguousComponentResolutionException if ambiguity happens. @throws CyclicDependencyException if cyclic dependency is detected. @throws UnresolvedComponentException if any component cannot be resolved. @throws UnsatisfiedComponentException if some requirement of a component cannot be satisfied. @throws YanException for any other exception.
