Method Detail

_allDebug

public static void _allDebug(boolean setting)

_debug

public PyObject _debug(int maxCount)

__dir__

public PyObject __dir__()

Description copied from class: PyObject

Equivalent to the standard Python __dir__ method.

Overrides:

__dir__ in class PyObject

Returns:

a list of names defined by this object.

__setattr__

public void __setattr__(java.lang.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

See Also:

PyObject.__setattr__(PyString, PyObject)

__delattr__

public void __delattr__(java.lang.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 .

See Also:

PyObject.__delattr__(PyString)

__findattr_ex__

public PyObject __findattr_ex__(java.lang.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

interpret

protected PyObject interpret(PyFrame f,
                             ThreadState ts)

Specified by:

interpret in class PyBaseCode

getline

protected int getline(PyFrame f)

Overrides:

getline in class PyBaseCode

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
