[jboss-user] [JBoss Cache: Core Edition] - snippet of code for eviction policy

[syreo]

Hello,

I am using Jboss cache and i having some issues configuring the eviction policy...
I am not using the xml configuration file, i want to do it programmatically.
The problem is, i haven't found neither in the user guide, nor in the javadoc, an example of code that explain how to configure an eviction policy...
For instance, i want to use the expiration algorithm on a node so this one is evict 2 seconds after being created.
I used this:
       
  | CacheFactory cacheFactory = new DefaultCacheFactory();
  | 		Configuration config = new Configuration();
  | 		Cache cache = cacheFactory.createCache(config);
  | 
  | 		Fqn fqn = Fqn.fromString("/foo/bar");
  | 		ExpirationAlgorithmConfig eac = new ExpirationAlgorithmConfig();
  | 		eac.setTimeToLive(2L, TimeUnit.SECONDS);
  | 		eac.setExpirationKeyName(ExpirationAlgorithmConfig.EXPIRATION_KEY);
  | 		EvictionRegionConfig erc = new EvictionRegionConfig(fqn, eac);
  | 		
  | 		Region region = cache.getRegion(fqn, true);
  | 		region.setEvictionRegionConfig(erc);
  | 		EvictionConfig ec = new EvictionConfig(erc);
  | 		cache.getConfiguration().setEvictionConfig(ec);
  | 		
  | 		Long future = new Long(System.currentTimeMillis() + 2000);
  | 		cache.getRoot().addChild(fqn).put(ExpirationAlgorithmConfig.EXPIRATION_KEY, future);
  | 		
  | 		boolean shouldbetrue = cache.getRoot().hasChild(fqn);
  | 		System.out.println(shouldbetrue);
  | 		
  | 		Thread.sleep(5000);
  | 		
  | 		boolean shouldbefalse = cache.getRoot().hasChild(fqn);
  | 		System.out.println(shouldbefalse);

I used the code from the user's guide (10.4.5) but there are quite a bunch of object to set properly i guess in order for this snippet to work (ExpirationAlgorithmConfig, EvictionRegionConfig, Region, EvictionConfig...)
I really don't know how to do this...
Thanks for your help!
