public void write(Kryo kryo, Output output, java.util.Optional 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:

object
- May be null ifSerializer.getAcceptsNull()
is true.

read
public java.util.Optional 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

copy
public java.util.Optional copy(Kryo kryo, java.util.Optional original)
Description copied from class:Serializer
Returns a copy of the specified object. The default implementation returns the original ifSerializer.isImmutable()
is true, else throwsKryoException
. Subclasses can optionall override this method to supportKryo.copy(Object)
.Before Kryo can be used to copy child objects,
Kryo.reference(Object)
must be called with the copy to ensure it can be referenced by the child objects. A serializer that usesKryo
to copy a child object may need to be reentrant.This method should not be called directly, instead this serializer can be passed to
