static <R> R |
callWithInterceptorChain(InterceptorChain interceptorChain,
Callable<R> action)
Invoke the given
action with the given interceptorChain being available
for parameter injection. |
ParameterResolver<InterceptorChain> |
createInstance(Executable executable,
Parameter[] parameters,
int parameterIndex)
If available, creates a ParameterResolver instance that can provide a parameter of type
parameterType for a given message. |

currentInterceptorChain()
Returns the current interceptor chain registered for injection as a parameter.

matches(Message<?> message)
Indicates whether this resolver is capable of providing a value for the given
message . |
