public interface ContextCapturer

A contract for passing ContextsContainer objects between threads. This is specifically useful to pass these objects between an inbound and outbound channel during request processing.
Once, the ContextsContainer objects is attached to a channel, via Attribute, it is recommended to pick it up from there instead of worrying about the threads on which it is put.
