Class LocalCache.ManualSerializationProxy<K,V>

java.lang.Object

com.google.common.collect.ForwardingObject

com.google.common.cache.ForwardingCache<K,V>

com.google.common.cache.LocalCache.ManualSerializationProxy<K,V>

All Implemented Interfaces:

Cache<K,V>, java.io.Serializable

Direct Known Subclasses:

LocalCache.LoadingSerializationProxy

Enclosing class:

LocalCache<K,V>

static class LocalCache.ManualSerializationProxy<K,V>
extends ForwardingCache<K,V>
implements java.io.Serializable

Serializes the configuration of a LocalCache, reconstituting it as a Cache using CacheBuilder upon deserialization. An instance of this class is fit for use by the writeReplace of LocalManualCache.

Unfortunately, readResolve() doesn't get called when a circular dependency is present, so the proxy must be able to behave as the cache itself.

delegate

protected Cache<K,V> delegate()

Description copied from class: ForwardingObject

Returns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.

Specified by:

delegate in class ForwardingCache<K,V>
