Examples of org.infinispan.marshall.core.MarshalledValue

org.infinispan.marshall.core.MarshalledValue
Wrapper that wraps cached data, providing lazy deserialization using the calling thread's context class loader.
The {@link org.infinispan.interceptors.MarshalledValueInterceptor} handles transparent wrapping/unwrapping of cacheddata.
NOTE: the equals() method of this class will compare binary representations (byte arrays).
Note also that this will affect the way keys stored in the cache will work, if storeAsBinary is used, since comparisons happen on the key which will be wrapped by a {@link MarshalledValue}. Implementers of equals() methods of their keys need to be aware of this.
This class can be marshalled either via its externalizer or via the JVM serialization. The reason for supporting both methods is to enable third-party libraries to be able to marshall/unmarshall them using standard JVM serialization rules. The Infinispan marshalling layer will always chose the most performant one, aka the externalizer method. @author Manik Surtani (manik@jboss.org) @author Mircea.Markus@jboss.com @author Galder Zamarreño @author Sanne Grinovero @see org.infinispan.interceptors.MarshalledValueInterceptor @since 4.0
