public class BeanSerializer<T> extends Serializer<T>
Serializes Java beans using bean accessor methods. Only bean properties with both a getter and setter are serialized. This class is not as fast asFieldSerializer
but is much faster and more efficient than Java serialization. Bytecode generation is used to invoke the bean property methods, if possible.BeanSerializer does not write header data, only the object data is stored. If the type of a bean property is not final (note primitives are final) then an extra byte is written for that property.

Method Detail

write
public void write(Kryo kryo, Output output, T 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<T>
object
- May be null ifSerializer.getAcceptsNull()
is true.
-
read
public T read(Kryo kryo, Input input, Class<? extends T> 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<T>
- Returns:
- May be null if
Serializer.getAcceptsNull()
is true.
-
copy
public T copy(Kryo kryo, T 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
Kryo
copy methods that accept a serialier.- Overrides:
