From c6b06e40dc859125cf76bec4632bd76de42256bd Mon Sep 17 00:00:00 2001 From: Kinsey Moore Date: Fri, 8 Mar 2013 16:00:14 +0000 Subject: Add message dump capability to stasis cache layer The cache dump mechanism allows the developer to retreive multiple items of a given type (or of all types) from the cache residing in a stasis caching topic in addition to the existing single-item cache retreival mechanism. This also adds to the caching unit tests to ensure that the new cache dump mechanism is functioning properly.
