Direct Known Subclasses:
  PyArray, PyList, PyString, PyTuple, PyXRange

public abstract class PySequence
extends PyObject

The abstract superclass of PyObjects that implements a Sequence. Minimize the work in creating such objects. Method names are designed to make it possible for PySequence to implement java.util.List interface when JDK 1.2 is ubiquitous. All subclasses must declare that they implement the ClassDictInit interface, and provide an classDictInit() method that calls PySequence.classDictInit(). Subclasses must also implement get, getslice, and repeat methods. Subclasses that are mutable should also implement: set, setslice, del, and delRange.
