    • 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
      PyObjects that implement org.python.core.finalization.HasFinalizeTrigger shall implement this method via:
      FinalizeTrigger.ensureFinalizer(this);

      __ensure_finalizer__ in class PyObject

    • traverseDerived

      public int traverseDerived(Visitproc visit, Object arg)
      Description copied from interface: TraverseprocDerived
      Traverses all reachable PyObjects. 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, Object arg)

    • __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.
