Class ExternalizableSerializer

java.lang.Object

com.esotericsoftware.kryo.Serializer

com.esotericsoftware.kryo.serializers.ExternalizableSerializer

public class ExternalizableSerializer
extends Serializer

Writes using the objects externalizable interface if it can reliably do so. Typically, a object can be efficiently written with Kryo and Java's externalizable interface. However, there may be behavior problems if the class uses either the 'readResolve' or 'writeReplace' methods. We will fall back onto the standard JavaSerializer if we detect either of these methods.

Note that this class does not specialize the type on Externalizable. That is because if we fall back on the JavaSerializer it may have an readResolve method that returns an object of a different type.

Method Detail

write

public void write(Kryo kryo,
                  Output output,
                  Object object)

Description copied from class: Serializer

Writes the bytes for the object to the output.

This method should not be called directly, instead this serializer can be passed to Kryo write methods that accept a serialier.

Specified by:

write in class Serializer

object - May be null if Serializer.getAcceptsNull() is true.

read

public Object read(Kryo kryo,
                   Input input,
                   Class type)

Description copied from class: Serializer

Reads bytes and returns a new object of the specified concrete type.

Before Kryo can be used to read child objects, Kryo.reference(Object) must be called with the parent object to ensure it can be referenced by the child objects. Any serializer that uses Kryo to read a child object may need to be reentrant.

This method should not be called directly, instead this serializer can be passed to Kryo read methods that accept a serialier.

Specified by:

read in class Serializer

Returns:

May be null if Serializer.getAcceptsNull() is true.
