Class NoExpiryCacheInvalidationPolicy
java.lang.Object
org.eclipse.persistence.descriptors.invalidation.CacheInvalidationPolicy
org.eclipse.persistence.descriptors.invalidation.NoExpiryCacheInvalidationPolicy
- All Implemented Interfaces:
- java.io.Serializable
public class NoExpiryCacheInvalidationPolicy
- extends CacheInvalidationPolicy
PUBLIC:
A cache invalidation policy in which no objects will expire. The only way for objects
to become invalid in the cache is for them to be explicitly set to invalid through
method calls on the IdentityMapAccessor. This is the default cache invalidation policy.
