Class JacksonCompactSerializer<T>

java.lang.Object
com.norconex.crawler.core.cluster.impl.hazelcast.JacksonCompactSerializer<T>
Type Parameters:
T - the value type
All Implemented Interfaces:
com.hazelcast.nio.serialization.compact.CompactSerializer<T>
public class JacksonCompactSerializer<T> extends Object implements com.hazelcast.nio.serialization.compact.CompactSerializer<T>
A generic Hazelcast Compact serializer that delegates to Jackson (via SerialUtil) for the actual serialization. The object graph is stored as a single JSON string field inside the Compact frame.

This avoids the overhead of Java Serializable class descriptors while reusing the already-tested Jackson mapping for complex types such as CrawlerEntry and its subclasses.
