public static class Maps.ManagedCacheMap<K,V> extends Maps.CacheMap<K,V> implements Maps.ManagedCacheMapMBean
This map will be registered with the MBean server using the following object name, where name
is the name given in the constructor:
"oracle.javatools.cache:type=CacheMap,name="O___name____pre___tt____Typically__the_given_name_should_uniquely_identify_the_instance_object____which_contains_and_uses_the_map__If_that_instance_object_is_a_singleton_____its_class_name_is_typically_sufficient__if_not__then_an_additional____distinguishing_property_should_be_appended__For_example__if_the_containing____instances_are_uniquely_characterized_by_a_URL_property__then_the_string____passed_to_the_constructor_could_be_______tt__pre___getClass___getSimpleName_____",url=" + getUrl()Notice how the URL is appended as an additional property, separated by a comma (",url="). This is not strictly required, but better fits standard JMX object naming conventions. Also note that if the value contains certain characters (for example, a file path if a URL contained a "?" or a file name contained a "\", see
ObjectName
), it must be quoted using ObjectName.quote(java.lang.String)

Maps.CacheMap
constructor to allow a subclass to replace the strategy passed to the constructor. The default Maps.CacheMap
implementation returns the strategy passed to it.
This hook is provided to allow a subclass to decorate a strategy given to its constructor without running afoul of superclass-not- initialized issues.
