Examples of StreamCache

org.apache.camel.StreamCache
Tagging interface to indicate that a type is capable of caching the underlying data stream.
This is a useful feature for avoiding message re-readability issues. This interface is mainly used by the {@link org.apache.camel.processor.interceptor.StreamCachingInterceptor}for determining if/how to wrap a stream-based message. @version
