Class CachingDestinationResolverProxy<D>

java.lang.Object
org.springframework.messaging.core.CachingDestinationResolverProxy<D>
Type Parameters:
D - the destination type
All Implemented Interfaces:
org.springframework.beans.factory.InitializingBean, DestinationResolver<D>
public class CachingDestinationResolverProxy<D> extends Object implements DestinationResolver<D>, org.springframework.beans.factory.InitializingBean
DestinationResolver implementation that proxies a target DestinationResolver, caching its resolveDestination(java.lang.String) results. Such caching is particularly useful if the destination resolving process is expensive (e.g. the destination has to be resolved through an external system) and the resolution results are stable anyway.
