java.lang.Object oracle.javatools.util.Maps.AbstractHashMap<K,V,E> oracle.javatools.util.Maps.AbstractLinkedHashMap<K,V,Maps.LinkedEntry<K,V>> oracle.javatools.util.Maps.CacheMap<K,V> oracle.javatools.util.Maps.ManagedCacheMap<K,V>
public static class Maps.ManagedCacheMap<K,V>
A cache map which is an MBean and can be monitored by a JMX client (e.g., JConsole).
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=" + name
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:
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)
.

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.
