com.ibm.portal.cache
Interface DependencyCache<K,V>

All Superinterfaces:

Cache<K,V>, Identifiable

public interface DependencyCache<K,V>
extends Cache<K,V>

Implementations of this interface also support dependency ID's for entries inserted into a cache. These dependencies are used to determine entries that rely on each other and need to be invalidated if one of them gets invalidated.

Here is how to access the caches

    com.ibm.com.portal.cache.Cache cache = com.ibm.wps.services.cache.CacheManager.getCacheFactory().
              getCache("UNIQUE_NAME_IN_THE_PORTAL_SCOPE");

Cache, com.ibm.wps.services.cache.CacheManager

Method Summary
void	put(K key, V value, java.lang.Object[] dependencyIds)           Place an entry in the cache.

Method Detail

put

void put(K key,
         V value,
         java.lang.Object[] dependencyIds)

Place an entry in the cache. Note that there is no guarantee that the object will actually end up in the cache. The underlying cache implementation can choose not to actually store this key-value pair based on whatever arbitrary conditions it chooses.

Later on invalidating the key from the cache will also invalidate all dependencyIds.

Parameters:

key - - the cache key, used to locate the entry on subsequent lookups.

value - - the object to store in the cache under this key

dependencyIds - - a set of dependency ids to associate with the cache entry.
