AbstractReference

                         PyObject callback)

Method Detail

py

protected PyObject py()

equals

public boolean equals(java.lang.Object ob_other)

Description copied from class: PyObject

Should almost never be overridden. If overridden, it is the subclasses responsibility to ensure that a.equals(b) == true iff cmp(a,b) == 0

Overrides:

equals in class PyObject

hasCallback

public boolean hasCallback()

hashCode

public int hashCode()

Overrides:

hashCode in class PyObject

__eq__

public PyObject __eq__(PyObject other)

Description copied from class: PyObject

Equivalent to the standard Python __eq__ method.

Overrides:

__eq__ in class PyObject

Parameters:

other - the object to compare this with.

Returns:

the result of the comparison.

__ne__

public PyObject __ne__(PyObject other)

Description copied from class: PyObject

Equivalent to the standard Python __ne__ method.

Overrides:

__ne__ in class PyObject

Parameters:

other - the object to compare this with.

Returns:

the result of the comparison.

get

protected PyObject get()

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
