ch.rasc.wampspring.support.HandlerMethodArgumentResolverComposite

All Implemented Interfaces:

HandlerMethodArgumentResolver

public class HandlerMethodArgumentResolverComposite
extends Object
implements HandlerMethodArgumentResolver

Resolves method parameters by delegating to a list of registered HandlerMethodArgumentResolver. Previously resolved method parameters are cached for faster lookups.

Credit goes to the Spring class org.springframework.messaging.handler.invocation.HandlerMethodArgumentResolverComposite . This class is just a copy where org.springframework.messaging.Message is replaced with WampMessage
