org.broadleafcommerce.common.extensibility.cache.ehcache.DefaultEhCacheUtil

All Implemented Interfaces:

public class DefaultEhCacheUtil
extends DefaultJCacheUtil

Allows an encapsulated way to create caches programmatically from an EhCache CacheManager. The standard APIs do not provide enough control, so we encapsulate those details here.

Method Detail

getCache

public <K,V> javax.cache.Cache<K,V> getCache(String cacheName)

Description copied from interface: JCacheUtil

Returns the cache associated with the name or null if no cache exists.

Specified by:

getCache in interface JCacheUtil

Overrides:

getCache in class DefaultJCacheUtil

Returns:

createCache

public javax.cache.Cache<Object,Object> createCache(String cacheName,
                                                    int ttlSeconds,
                                                    int maxElementsInMemory)

Description copied from interface: JCacheUtil

Returns a new Cache with the appropriate cache name, TTL, and maxElements. If the cache exists, an exception will be thrown. The ttl and maxElementsInMemory settings may be implementation specific and so implementors may choose to ignore these arguments. If ttlSeconds is less than 1 then the cache will not expire.

Specified by:

createCache in interface JCacheUtil

Overrides:

createCache in class DefaultJCacheUtil

Returns:
