Method Detail

__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__(String key)

Description copied from class: PyObject

A variant of the __finditem__ method which accepts a Java String 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. Warning: key must be an interned string!!!!!!!!

Overrides:

__finditem__ in class PyObject

Parameters:

key - the key to lookup in this sequence - must be an interned string .

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__(String key,
                        PyObject value)

Description copied from class: PyObject

A variant of the __setitem__ method which accepts a String as the key. This String must be interned. By default, this will call __setitem__(PyObject key, PyObject value) with the appropriate args. The only reason to override this method is for performance.

Overrides:

__setitem__ in class PyObject

Parameters:

key - the key whose value will be set - must be an interned string .

value - the value to set this key to

See Also:

PyObject.__setitem__(PyObject, PyObject)

__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__(String key)

Description copied from class: PyObject

A variant of the __delitem__ method which accepts a String as the key. This String must be interned. By default, this will call __delitem__(PyObject key) with the appropriate args. The only reason to override this method is for performance.

Overrides:

__delitem__ in class PyObject

Parameters:

key - the key who will be removed - must be an interned string .

See Also:

PyObject.__delitem__(PyObject)

__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

clear

public void clear()

Remove all items from the dictionary.

toString

public String toString()

__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 < 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)

Return this[key] if the key exists in the mapping, default_object is returned otherwise.

Parameters:

key - the key to lookup in the mapping.

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

get

public PyObject get(PyObject key)

Return this[key] if the key exists in the mapping, None is returned otherwise.

Parameters:

key - the key to lookup in the mapping.

copy

public PyStringMap copy()

Return a shallow copy of the dictionary.

update

public void update(PyStringMap map)

Insert all the key:value pairs from map into this mapping.

update

public void update(PyDictionary dict)

Insert all the key:value pairs from dict into this mapping.

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 mapping.

setdefault

public PyObject setdefault(PyObject key,
                           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 mapping.

failobj - the default value to insert in the mapping if key does not already exist.

popitem

public PyObject popitem()

Return a random (key, value) tuple pair and remove the pair from the mapping.

items

public PyList items()

Return a copy of the mappings list of (key, value) tuple pairs.

keys

public PyList keys()

Return a copy of the mappings list of keys.

values

public PyList values()

Return a copy of the mappings list of values.
