public class PyDefaultDict
extends PyDictionary

PyDefaultDict - This is a subclass of the builtin dict(PyDictionary) class. It supports one additional method __missing__ and adds one writable instance variable defaultFactory. The remaining functionality is the same as for the dict class. collections.defaultdict([defaultFactory[, ...]]) - returns a new dictionary-like object. The first argument provides the initial value for the defaultFactory attribute; it defaults to None. All remaining arguments are treated the same as if they were passed to the dict constructor, including keyword arguments.

Method Detail

__finditem__

public PyObject __finditem__(PyObject key)
Description copied from class: PyObject
Very similar to the standard Python __getitem__ method. Instead of throwing a KeyError if the item isn't found, this just returns null. Classes that wish to implement __getitem__ should override this method instead (with the appropriate semantics.

Overrides:
__finditem__ in class PyDictionary
Parameters:
key - the key to lookup in this container
Returns:
the value corresponding to key or null if key is not found

__reduce__

public PyObject __reduce__()
Description copied from class: PyObject
Used for pickling. Default implementation calls object___reduce__.

Overrides:
__reduce__ in class PyObject
Returns:
a tuple of (class, tuple)

copy

public PyDictionary copy()
Description copied from class: PyDictionary
Return a shallow copy of the dictionary.

Overrides:
copy in class PyDictionary

toString

public String toString()
Overrides:
toString in class PyDictionary

getDefaultFactory

public PyObject getDefaultFactory()

setDefaultFactory

public void setDefaultFactory(PyObject value)

delDefaultFactory
