Class OSCacheImplementation

java.lang.Object
  org.mmbase.cache.oscache.OSCacheImplementation

All Implemented Interfaces:

CacheImplementationInterface, Map

public class OSCacheImplementation

extends Object

implements CacheImplementationInterface

Implementation of the MMBase 'CacheImplementationInterface' interface, which delegates all calls to an OSCache implementation. This implementation accepts the following configuration properties:

• path

To use this implementation, you can use a construction like this in your 'caches.xml' configuration file:

 <cache name="NodeListCache">
   <status>active</status>
   <size>3</size>
   <implementation>
     <class>org.mmbase.cache.oscache.OSCacheImplementation</class>
     <param name="path">/tmp</param>
   </implementation>
 </cache>
