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 standardJavaSerializer
if we detect either of these methods. Note that this class does not specialize the type onExternalizable
. That is because if we fall back on theJavaSerializer
it may have anreadResolve
method that returns an object of a different type.- Author:

write
public void write(Kryo kryo, Output output, java.lang.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 classSerializer
object
- May be null ifSerializer.getAcceptsNull()
is true.

read
public java.lang.Object read(Kryo kryo, Input input, java.lang.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 usesKryo
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 classSerializer
- Returns:
- May be null if
Serializer.getAcceptsNull()
is true.
