Class DefaultSerializationMapper

java.lang.Object

com.mulesoft.mule.runtime.module.serialization.kryo.internal.mapper.DefaultSerializationMapper

All Implemented Interfaces:

SerializationMapper

public class DefaultSerializationMapper
extends Object
implements SerializationMapper

This class was created to change the serialization for instances of the class Timestamp, while preserving backwards compatibility with old serialized versions, but it can be extended for new classes X with the same backwards considerations:

For old serialized objects: If you have an instance of a class X already serialized, this logic won't alter the deserialization. This is the important part to preserve backwards.

For new objects to be serialized: If you have an instance of X and you want to serialize it with a different logic, you can add some logic in the method mapBeforeSerialization(Object). It should wrap the instance of X into an instance of W(X). For the original Timestamp case, it will be wrapped in a TimestampWrapper instance.

For serialized instances of new W(X): after deserializing the instance of the wrapper, you have to add the symmetric logic to mapAfterDeserialization(Object). It will be called after than an object was deserialized.

Method Detail

mapBeforeSerialization

public Object mapBeforeSerialization(Object original)

Description copied from interface: SerializationMapper

Wraps the passed object into another object if it's needed for serialization. This method must be symmetric with SerializationMapper.mapAfterDeserialization(Object).

Specified by:

mapBeforeSerialization in interface SerializationMapper

Parameters:

original - the object to be wrapped.

Returns:

a wrapped version of the original object if it's needed, or the same object otherwise.

mapAfterDeserialization

public Object mapAfterDeserialization(Object deserialized)

Description copied from interface: SerializationMapper

Builds an object from the passed object if it's a wrapper. This method must be symmetric with SerializationMapper.mapBeforeSerialization(Object).

Specified by:

mapAfterDeserialization in interface SerializationMapper

Parameters:

deserialized - the object that was deserialized.

Returns:

the unwrapped version of the passed object if it's a wrapper, or the same object otherwise.
