### Methods inherited from class java.lang.Object

### Field Detail

#### TYPE

    public static final PyType TYPE

#### args

    public PyObject args

Exception's arguments.

#### __dict__

    public PyObject __dict__

Exception's underlying dictionary, lazily created.

### Constructor Detail

#### PyBaseException

    public PyBaseException()

#### PyBaseException

    public PyBaseException(PyType subType)

### Method Detail

#### __init__

    public void __init__(PyObject[] args,
                         java.lang.String[] keywords)

#### __getitem__

    public PyObject __getitem__(PyObject index)

Description copied from class: `PyObject`
Equivalent to the standard Python __getitem__ method. This method should not be overridden. Override the `__finditem__` method instead.

Overrides:
  `__getitem__` in class `PyObject`
Parameters:
  `index` - the key to lookup in this container.
Returns:
  the value corresponding to that key.
See Also:
  `PyObject.__finditem__(PyObject)`

#### __getslice__

    public PyObject __getslice__(PyObject start,
                                 PyObject stop)

Overrides:
  `__getslice__` in class `PyObject`

#### __reduce__

    public PyObject __reduce__()

Description copied from class: `PyObject`
Used for pickling. Default implementation calls object___reduce__.

Overrides:
  `__reduce__` in class `PyObject`
Returns:
  a tuple of (class, tuple)

#### __setstate__

    public PyObject __setstate__(PyObject state)

#### __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,
                            PyObject value)

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)`

#### fastGetDict

    public PyObject fastGetDict()

Description copied from class: `PyObject`
xxx implements where meaningful

Overrides:
  `fastGetDict` in class `PyObject`
Returns:
  internal object per instance dict or null

#### getDict

    public PyObject getDict()

Description copied from class: `PyObject`
xxx implements where meaningful

Overrides:
  `getDict` in class `PyObject`
Returns:
  internal object __dict__ or null

#### setDict

    public void setDict(PyObject val)

Overrides:
  `setDict` in class `PyObject`

#### __str__

    public PyString __str__()

Description copied from class: `PyObject`
Equivalent to the standard Python __str__ method. The default implementation (in `PyObject`) calls `PyObject.__repr__()`, making it unnecessary to override `__str__` in sub-classes of `PyObject` where both forms are the same. A common choice is to provide the same implementation to `__str__` and `toString`, for consistency in the printed form of objects between Python and Java.

Overrides:
  `__str__` in class `PyObject`

#### __unicode__

    public PyUnicode __unicode__()

Overrides:
  `__unicode__` in class `PyObject`

#### toString

    public java.lang.String toString()

Overrides:
  `toString` in class `PyObject`

#### setArgs

    public void setArgs(PyObject val)

#### getMessage

    public PyObject getMessage()

#### setMessage

    public void setMessage(PyObject value)

#### delMessage

    public void delMessage()

#### traverse

    public int traverse(Visitproc visit,
                        java.lang.Object arg)

Description copied from interface: `Traverseproc`
Traverses all directly contained `PyObject`s. Like in CPython, `arg` must be passed unmodified to `visit` as its second parameter. If `Visitproc.visit(PyObject, Object)` returns nonzero, this return value must be returned immediately by traverse. `Visitproc.visit(PyObject, Object)` must not be called with a `null` PyObject-argument.

Specified by:
  `traverse` in interface `Traverseproc`

#### refersDirectlyTo

    public boolean refersDirectlyTo(PyObject ob)

Description copied from interface: `Traverseproc`
Optional operation. Should only be implemented if it is more efficient than calling `Traverseproc.traverse(Visitproc, Object)` with a visitproc that just watches out for `ob`. Must return `false` if `ob` is `null`.

Specified by:
  `refersDirectlyTo` in interface `Traverseproc`
