Package org.onebusaway.container.cache

Class DefaultCacheableKeyFactory

java.lang.Object

org.onebusaway.container.cache.DefaultCacheableKeyFactory

All Implemented Interfaces:

Serializable, CacheableMethodKeyFactory

public class DefaultCacheableKeyFactory
extends Object
implements CacheableMethodKeyFactory, Serializable

Factory for producing a CacheKeyInfo cache key from a ProceedingJoinPoint method invocation. The default implementation considers each argument to the method invocation and applies a CacheableObjectKeyFactory to produce a Serializable key value for that argument. An array of those Serializable key values are composed together to make the final cache key. The CacheKeyInfo.isCacheRefreshIndicated() cache refresh indicators from each argument key are ORed together to produce a refresh indicator for the entire method.
