Method Detail

hashCode

public int hashCode()

Overrides:

hashCode in class PyObject

__eq__

public PyObject __eq__(PyObject o)

Description copied from class: PyObject

Equivalent to the standard Python __eq__ method.

Overrides:

__eq__ in class PyObject

Parameters:

o - the object to compare this with.

Returns:

the result of the comparison.

__ne__

public PyObject __ne__(PyObject o)

Description copied from class: PyObject

Equivalent to the standard Python __ne__ method.

Overrides:

__ne__ in class PyObject

Parameters:

o - the object to compare this with.

Returns:

the result of the comparison.

indices

public PyObject indices(PyObject len)

indicesEx

public int[] indicesEx(int length)

Calculates the actual indices of a slice with this slice's start, stop, step and slicelength values for a sequence of length len.

Returns:

an array with the start at index 0, stop at index 1, step at index 2 and slicelength at index 3

indices2

public static PyObject[] indices2(PyObject obj,
                                  PyObject start,
                                  PyObject stop)

Calculate indices for the deprecated __get/set/delslice__ methods.

Parameters:

obj - the object being sliced

start - the slice operation's start

stop - the slice operation's stop

Returns:

an array with start at index 0 and stop at index 1

calculateSliceIndex

public static int calculateSliceIndex(PyObject v)

toString

public java.lang.String toString()

Overrides:

toString in class PyObject

getStart

public final PyObject getStart()

getStop

public final PyObject getStop()

getStep

public final PyObject getStep()

traverse

public int traverse(Visitproc visit,
                    java.lang.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
