Deprecated.
This class has been deprecated with no replacement,
because serialization can be a security liability
An encoder which serializes a Java object into a
ByteBuf
.
Please note that the serialized form this encoder produces is not
compatible with the standard ObjectInputStream
. Please use
ObjectDecoder
or ObjectDecoderInputStream
to ensure the
interoperability with this encoder.
Security: serialization can be a security liability, and should not be used without defining a list of classes that are allowed to be desirialized. Such a list can be specified with the jdk.serialFilter system property, for instance. See the serialization filtering article for more information.
