      Parameters:
      obj - the object to convert
      Returns:
      the bytes
      Throws:
      IOException - if an I/O error occurs

    • toObject

      @Deprecated(forRemoval=true) public static <T> T toObject(InputStream inputStream, Class<T> class1) throws IOException, ClassNotFoundException

      Converts an input stream to an object, with the Java serialization. The stream may hold only an instance of the given class and the types of java.lang, java.util and java.time: any other class is rejected.
      Type Parameters:
      T - the type of the object
      Parameters:
      inputStream - the input stream
      class1 - the class of the object
      Returns:
      an instance of type "type"
      Throws:
      IOException - if an I/O error occurs
      ClassNotFoundException - if the class of a serialized object cannot be found
      InvalidClassException - if the stream holds a class that is not accepted
