    • serialize

      public void serialize(PofWriter out, Optional value) throws IOException
      Description copied from interface: PofSerializer
      Serialize a user type instance to a POF stream by writing its state using the specified PofWriter object.

      An implementation of PofSerializer is required to follow the following steps in sequence for writing out an object of a user type:

      1. If the object is evolvable, the implementation must set the version by calling PofWriter.setVersionId(int).
      2. The implementation may write any combination of the properties of the user type by using the "write" methods of the PofWriter, but it must do so in the order of the property indexes.
      3. After all desired properties of the user type have been written, the implementation must terminate the writing of the user type by calling PofWriter.writeRemainder(com.tangosol.util.Binary).
      Specified by:
      serialize in interface PofSerializer<Optional>
      Parameters:
      out - the PofWriter with which to write the object's state
      value - the object to serialize
      Throws:
      IOException - if an I/O error occurs

    • deserialize

      public Optional deserialize(PofReader in) throws IOException
      Description copied from interface: PofSerializer
      Deserialize a user type instance from a POF stream by reading its state using the specified PofReader object.

      An implementation of PofSerializer is required to follow the following steps in sequence for reading in an object of a user type:

      1. If the object is evolvable, the implementation must get the version by calling PofReader.getVersionId().
      2. The implementation may read any combination of the properties of the user type by using "read" methods of the PofReader, but it must do so in the order of the property indexes. Additionally, the implementation must call PofReader.registerIdentity(java.lang.Object) with the new instance prior to reading any properties which are user type instances themselves.
      3. After all desired properties of the user type have been read, the implementation must terminate the reading of the user type by calling PofReader.readRemainder().
      Specified by:
      deserialize in interface PofSerializer<Optional>
      Parameters:
      in - the PofReader with which to read the object's state
      Returns:
      the deserialized user type instance
      Throws:
      IOException - if an I/O error occurs
