    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.

Constructor Detail

### PyDefaultDict

    public PyDefaultDict()

### PyDefaultDict

### PyDefaultDict

    public PyDefaultDict(PyType subtype,
                         Map<PyObject,PyObject> map)

Method Detail

### getMap

    public ConcurrentMap<PyObject,PyObject> getMap()

  Overrides:
    `getMap` in class `PyDictionary`

### __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

    public void delDefaultFactory()

### __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
