Constructor Detail

### PyDictionary

    public PyDictionary()

  Create an empty dictionary.

### PyDictionary

    public PyDictionary(java.util.Hashtable t)

  Create an new dictionary which is based on the hashtable.

Parameters:
  `t` - the hashtable used. The supplied hashtable is used as is and must only contain PyObject key:value pairs.

### PyDictionary

    public PyDictionary(PyObject[] elements)

  Create a new dictionary with the element as content.

Parameters:
  `elements` - The initial elements that is inserted in the dictionary. Even numbered elements are keys, odd numbered elements are values.

Method Detail

### classDictInit

    public static void classDictInit(PyObject dict)

  Internal use only. Do not call this method explicit.

### safeRepr

    public java.lang.String safeRepr()
                              throws PyIgnoreMethodTag

  Overrides:
    `safeRepr` in class `PyObject`
    `PyIgnoreMethodTag`

### __findattr__

    public PyObject __findattr__(java.lang.String name)

  Description copied from class: `PyObject`
  A variant of the __findattr__ method which accepts a Java `String` as the name. By default, this method will call `__findattr__(PyString name)` with the appropriate args. The only reason to override this method is for performance. Warning: name must be an interned string!!!!!!!!

  Overrides:
    `__findattr__` in class `PyObject`
  Parameters:
    `name` - the name to lookup in this namespace must be an interned string .
  Returns:
    the value corresponding to name or null if name is not found
  See Also:
    `PyObject.__findattr__(PyString)`

### __len__

    public int __len__()

  Description copied from class: `PyObject`
  Equivalent to the standard Python __len__ method. Part of the mapping discipline.

  Overrides:
    `__len__` in class `PyObject`
  Returns:
    the length of the object

### __nonzero__

    public boolean __nonzero__()

  Description copied from class: `PyObject`
  Equivalent to the standard Python __nonzero__ method. Returns whether of not a given `PyObject` is considered true.

  Overrides:
    `__nonzero__` in class `PyObject`

### __finditem__

    public PyObject __finditem__(int index)

  Description copied from class: `PyObject`
  A variant of the __finditem__ method which accepts a primitive `int` as the key. By default, this method will call `__finditem__(PyObject key)` with the appropriate args. The only reason to override this method is for performance.

  Overrides:
    `__finditem__` in class `PyObject`
  Parameters:
    `index` - the key to lookup in this sequence.
  Returns:
    the value corresponding to key or null if key is not found.
  See Also:
    `PyObject.__finditem__(PyObject)`

### __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 `PyObject`
  Parameters:
    `key` - the key to lookup in this container
  Returns:
    the value corresponding to key or null if key is not found

### __setitem__

    public void __setitem__(PyObject key,
                            PyObject value)

  Description copied from class: `PyObject`
  Equivalent to the standard Python __setitem__ method.

  Overrides:
    `__setitem__` in class `PyObject`
  Parameters:
    `key` - the key whose value will be set
    `value` - the value to set this key to

### __delitem__

    public void __delitem__(PyObject key)

  Description copied from class: `PyObject`
  Equivalent to the standard Python __delitem__ method.

  Overrides:
    `__delitem__` in class `PyObject`
  Parameters:
    `key` - the key to be removed from the container

### toString

    public java.lang.String toString()

  Overrides:
    `toString` in class `java.lang.Object`

### __cmp__

    public int __cmp__(PyObject ob_other)

  Description copied from class: `PyObject`
  Equivalent to the standard Python __cmp__ method.

  Overrides:
    `__cmp__` in class `PyObject`
  Parameters:
    `ob_other` - the object to compare this with.
  Returns:
    -1 if this < 0; 0 if this == o; +1 if this > o; -2 if no comparison is implemented

### has_key

    public boolean has_key(PyObject key)

  Return true if the key exist in the dictionary.

### get

    public PyObject get(PyObject key,
                        PyObject default_object)

    `default_object` - the value to return if the key does not exists in the mapping.

### get

  Insert all the key:value pairs from `d` into this dictionary.

### setdefault

    public PyObject setdefault(PyObject key)

  Return this[key] if the key exist, otherwise insert key with a None value and return None.

  Parameters:
    `key` - the key to lookup in the dictionary.

                               PyObject failobj)

  Return this[key] if the key exist, otherwise insert key with the value of failobj and return failobj

  Parameters:
    `key` - the key to lookup in the dictionary.
    `failobj` - the default value to insert in the dictionary if key does not already exist.
