      public static PyObject classobj___new__(PyObject name, PyObject bases, PyObject dict)

    • 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

    • __findattr_ex__

      public PyObject __findattr_ex__(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__(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

    • __delattr__

      public void __delattr__(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 .

    • __rawdir__

      public void __rawdir__(PyDictionary accum)

    • noAttributeError

      public void noAttributeError(String name)
      Customized AttributeError for class objects.
      Overrides:
      noAttributeError in class PyObject

    • __call__

      public PyObject __call__(PyObject[] args, String[] keywords)
      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.

    • isCallable

      public boolean isCallable()
      Overrides:
      isCallable in class PyObject

    • __cmp__

      public int __cmp__(PyObject other)
      Description copied from class: PyObject
      Equivalent to the standard Python __cmp__ method.
      Overrides:
      __cmp__ in class PyObject
      Parameters:
      other - the object to compare this with.
      Returns:
      -1 if this<o; 0 if this==o; +1 if this>o; -2 if no comparison is implemented

    • __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

    • toString

      public String toString()
      Overrides:
      toString in class PyObject

    • isSubClass

      public boolean isSubClass(PyClass superclass)

    • setDict

      public void setDict(PyObject value)
      Overrides:
      setDict in class PyObject

    • setBases

      public void setBases(PyObject value)

    • setName

      public void setName(PyObject value)

    • traverse

      public int traverse(Visitproc visit, Object arg)
      Description copied from interface: Traverseproc
      Traverses all directly contained PyObjects. 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
