Examples of org.infinispan.manager.CacheContainer

org.infinispan.manager.CacheContainer
A CacheContainer is the primary mechanism for retrieving a {@link org.infinispan.Cache} instance, and is oftenused as a starting point to using the {@link org.infinispan.Cache}.
CacheManagers are heavyweight objects, and we foresee no more than one CacheManager being used per JVM (unless specific configuration requirements require more than one; but either way, this would be a minimal and finite number of instances).
You obtain Cache instances from the CacheManager by using one of the overloaded getCache(), methods. Note that with getCache(), there is no guarantee that the instance you get is brand-new and empty, since caches are named and shared. Because of this, the CacheManager also acts as a repository of Caches, and is an effective mechanism of looking up or creating Caches on demand.
When the system shuts down, it should call {@link #stop()} on the CacheManager. This will ensure all cacheswithin its scope are properly stopped as well.
NB: Shared caches are supported (and in fact encouraged) but if they are used it's the users responsibility to ensure that at least one but only one caller calls stop() on the cache, and it does so with the awareness that others may be using the cache.
Sample usage: CacheManager manager = new DefaultCacheManager("my-config-file.xml"); Cache entityCache = manager.getCache("myEntityCache"); entityCache.put("aPerson", new Person());
Configuration myNewConfiguration = new Configuration(); myNewConfiguration.setCacheMode(Configuration.CacheMode.LOCAL); manager.defineConfiguration("myLocalCache", myNewConfiguration); Cache localCache = manager.getCache("myLocalCache"); @see org.infinispan.manager.EmbeddedCacheManager @author Manik Surtani (manik@jboss.org) @author Galder Zamarreño @author Mircea.Markus@jboss.com @since 4.0
