classobj___new__

                                        boolean init,
                                        PyType subtype,

fastGetDict

public PyObject fastGetDict()

Description copied from class: PyObject

xxx implements where meaningful

Overrides:

fastGetDict in class PyObject

Returns:

internal object per instance dict or null

__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

__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)

__rawdir__

public void __rawdir__(PyDictionary accum)

Overrides:

__rawdir__ in class PyObject

noAttributeError

public void noAttributeError(java.lang.String name)

Customized AttributeError for class objects.

Overrides:

noAttributeError in class PyObject

__call__

public PyObject __call__(PyObject[] args,
                         java.lang.String[] keywords)

Description copied from class: PyObject

The basic method to override when implementing a callable object. The first len(args)-len(keywords) members of args[] are plain arguments. The last len(keywords) arguments are the values of the keyword arguments.

Overrides:

__call__ in class PyObject

Parameters:

args - all arguments to the function (including keyword arguments).

keywords - the keywords used for all keyword arguments.

isCallable

public boolean isCallable()

Overrides:

isCallable in class PyObject

__cmp__

public int __cmp__(PyObject other)

Description copied from class: PyObject

Equivalent to the standard Python __cmp__ method.

Overrides:

__cmp__ in class PyObject

Parameters:

other - the object to compare this with.

Returns:

-1 if this<o; 0 if this==o; +1 if this>o; -2 if no comparison is implemented

__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.

Overrides:

__str__ in class PyObject

toString

public java.lang.String toString()

Overrides:

toString in class PyObject

isSubClass

public boolean isSubClass(PyClass superclass)

setDict

public void setDict(PyObject value)

Overrides:

setDict in class PyObject

setBases

public void setBases(PyObject value)

setName

public void setName(PyObject value)

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
