          public PyRawIOBaseDerived(PyType subtype)

  - ### Method Detail

    - #### getSlot

          public PyObject getSlot(int index)

      Specified by:
        `getSlot` in interface `Slotted`

    - #### setSlot

          public void setSlot(int index,
                              PyObject value)

      Specified by:
        `setSlot` in interface `Slotted`

    - #### __del_derived__

          public void __del_derived__()

      Description copied from interface: `FinalizablePyObjectDerived`
      `__del_builtin__` is the built-in's own finalizer, while `__del_derived__` refers to an instance's in-dict `__del__`. A FinalizeTrigger calls `__del_derived__` first and - if existent - `__del_builtin__` after that. A plain `__del__` would behave as overridden by `__del_derived__`, i.e. won't be called if the type implements `FinalizablePyObjectDerived` while `__del_builtin__` is called in any case.
      Specified by:
        `__del_derived__` in interface `FinalizablePyObjectDerived`

    - #### __ensure_finalizer__

          public void __ensure_finalizer__()

      Description copied from class: `PyObject`

        `__ensure_finalizer__` in class `PyObject`

    - #### traverseDerived

          public int traverseDerived(Visitproc visit,

      Description copied from interface: `TraverseprocDerived`
      Traverses all reachable `PyObject`s. Like in CPython, `arg` must be passed unmodified to `visit` as its second parameter.
      Specified by:
        `traverseDerived` in interface `TraverseprocDerived`

    - #### traverseDictIfAny

          public int traverseDictIfAny(Visitproc visit,

      Description copied from class: `PyObject`
      The basic method to override when implementing a callable object. The first len(args)-len(keywords) members of args[] are plain arguments. The last len(keywords) arguments are the values of the keyword arguments.
      Overrides:
        `__call__` in class `PyObject`
      Parameters:
        `args` - all arguments to the function (including keyword arguments).
        `keywords` - the keywords used for all keyword arguments.

    - #### __findattr_ex__

          public PyObject __findattr_ex__(java.lang.String name)

      Description copied from class: `PyObject`
      Attribute lookup hook. If the attribute is not found, null may be returned or a Py.AttributeError can be thrown, whatever is more correct, efficient and/or convenient for the implementing class. Client code should use `PyObject.__getattr__(String)` or `PyObject.__findattr__(String)`. Both methods have a clear policy for failed lookups.
      Overrides:
        `__findattr_ex__` in class `PyObject`
      Returns:
        The looked up value. May return null if the attribute is not found

    - #### __setattr__

          public void __setattr__(java.lang.String name,

      Description copied from class: `PyObject`
      A variant of the __setattr__ method which accepts a String as the key. This String must be interned.
      Overrides:
        `__setattr__` in class `PyObject`
      Parameters:
        `name` - the name whose value will be set - must be an interned string .
        `value` - the value to set this name to
      See Also:
        `PyObject.__setattr__(PyString, PyObject)`

    - #### __delattr__

          public void __delattr__(java.lang.String name)

      Description copied from class: `PyObject`
      A variant of the __delattr__ method which accepts a String as the key. This String must be interned. By default, this will call `__delattr__(PyString name)` with the appropriate args. The only reason to override this method is for performance.
      Overrides:
        `__delattr__` in class `PyObject`
      Parameters:
        `name` - the name which will be removed - must be an interned string .
      See Also:
        `PyObject.__delattr__(PyString)`

      Returns:
        - the object defined for this descriptor for the given obj and type.

    - #### __set__

          public void __set__(PyObject obj,

      Returns:
        this object

    - #### fileno

          public PyObject fileno()

      Description copied from class: `PyIOBase`
      Return a file descriptor for the stream. A CPython file descriptor is an int, but this is not the natural choice in Jython, since Java has no such convention of using integers. File descriptors should be passed around opaquely, so their actual type is irrelevant, as long as (say) `_jyio.open(PyObject[], String[])` accepts the type that `RawIOBase.fileno()` returns.
      Overrides:
        `fileno` in class `PyIOBase`
      Returns:
        a file descriptor (as opaque object)

      Description copied from class: `PyIOBase`
      Position the read or write pointer at a given byte offset `pos` relative to a position indicated by `whence`.
      - If `whence`=0, the position will be set to `pos` bytes.
      - If `whence`=1 the position will be set to the current position plus `pos`.
      - If `whence`=2 the position will be set to the stream size plus `pos` (and usually `pos`<=0).
      Overrides:
        `seek` in class `PyIOBase`
      Parameters:
        `pos` - relative to the specified point
        `whence` - 0=from start, 1=from here, 2=from end

      Returns:
        the new size

    - #### flush

          public void flush()

      Description copied from class: `PyIOBase`
      Flush write buffers, or no-op for read-only and non-blocking streams. Irrespective of the concrete type of the i/o object, locally-buffered write data is written downstream. Whether the downstream in object is also flushed depends upon the specific type of this object.
      Overrides:
        `flush` in class `PyIOBase`

    - #### close

          public void close()

      Description copied from class: `PyIOBase`
      Close the stream. If closed already, this is a no-op.
      Overrides:

      Description copied from class: `PyRawIOBase`
      Read until end of file, using multiple `read()` operations on the underlying stream. If the first `read()` returns `None` (only possible in the case of a non-blocking stream), this method returns `None`.
      Overrides:
        `readall` in class `PyRawIOBase`
