Class ObjectEncoderOutputStream

java.lang.Object
java.io.OutputStream
io.netty.handler.codec.serialization.ObjectEncoderOutputStream
All Implemented Interfaces:
java.io.Closeable, java.io.DataOutput, java.io.Flushable, java.io.ObjectOutput, java.lang.AutoCloseable
@Deprecated public class ObjectEncoderOutputStream extends java.io.OutputStream implements java.io.ObjectOutput
Deprecated.
This class has been deprecated with no replacement, because serialization can be a security liability
An ObjectOutput which is interoperable with ObjectDecoder and ObjectDecoderInputStream.

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.

    • ObjectEncoderOutputStream

      public ObjectEncoderOutputStream(java.io.OutputStream out)
      Deprecated.
      Creates a new ObjectOutput with the estimated length of 512 bytes.
      Parameters:
      out - the OutputStream where the serialized form will be written out

    • ObjectEncoderOutputStream

      public ObjectEncoderOutputStream(java.io.OutputStream out, int estimatedLength)
      Deprecated.
      Creates a new ObjectOutput.
      Parameters:
      out - the OutputStream where the serialized form will be written out
      estimatedLength - the estimated byte length of the serialized form of an object. If the length of the serialized form exceeds this value, the internal buffer will be expanded automatically at the cost of memory bandwidth. If this value is too big, it will also waste memory bandwidth. To avoid unnecessary memory copy or allocation cost, please specify the properly estimated value.
