/**
* BasicCache provides the common building block for the two different types of caches that Infinispan provides:
* embedded and remote.
* <p/>
* For convenience, BasicCache extends {@link ConcurrentMap} and implements all methods accordingly, although methods like
* {@link ConcurrentMap#keySet()}, {@link ConcurrentMap#values()} and {@link ConcurrentMap#entrySet()} are expensive
* (prohibitively so when using a distributed cache) and frequent use of these methods is not recommended.
* <p />
* Other methods such as {@link #size()} provide an approximation-only, and should not be relied on for an accurate picture
* as to the size of the entire, distributed cache. Remote nodes are <i>not</i> queried and in-fly transactions are not
* taken into account, even if {@link #size()} is invoked from within such a transaction.
* <p/>
* Also, like many {@link ConcurrentMap} implementations, BasicCache does not support the use of <tt>null</tt> keys or
* values.
* <p/>
* <h3>Unsupported operations</h3>
* <p>{@link #containsValue(Object)}</p>
*
* Please see the <a href="http://www.jboss.org/infinispan/docs">Infinispan documentation</a> and/or the <a
* href="https://docs.jboss.org/author/display/ISPN/Getting+Started+Guide#GettingStartedGuide-5minutetutorial">5 Minute Usage Tutorial</a> for more details.
