Class SerializedEntry<T>

java.lang.Object
  org.terracotta.cache.value.AbstractStatelessTimestampedValue<V>
      org.terracotta.cache.value.AbstractTimestampedValue<byte[]>
          org.terracotta.cache.serialization.SerializedEntry<T>

All Implemented Interfaces:

TimestampedValue<byte[]>

Direct Known Subclasses:

CustomLifespanSerializedEntry

public class SerializedEntry<T>
extends AbstractTimestampedValue<byte[]>

Wrapper class around the serialized cache entries. This handles the serialization and de-serialization of the cache entries, and also the local caching (in a transient reference) of the de-serialized value.
