Method Details

__len__
public int __len__()Description copied from class:PyObject
Equivalent to the standard Python __len__ method. Part of the mapping discipline. -
__nonzero__
public boolean __nonzero__()Description copied from class:PyObject
Equivalent to the standard Python __nonzero__ method. Returns whether of not a givenPyObject
is considered true.- Overrides:
__nonzero__
in classPyObject
-
__finditem__
Description copied from class:PyObject
A variant of the __finditem__ method which accepts a JavaString
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 classPyObject
- 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:
-
__finditem__
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 classPyObject
- Parameters:
key
- the key to lookup in this container- Returns:
- the value corresponding to key or null if key is not found
-
__iter__
Description copied from class:PyObject
Return an iterator that is used to iterate the element of this sequence. From version 2.2, this method is the primary protocol for looping over sequences.If a PyObject subclass should support iteration based in the __finditem__() method, it must supply an implementation of __iter__() like this:
public PyObject __iter__() { return new PySequenceIter(this); }
When iterating over a python sequence from java code, it should be done with code like this:PyObject iter = seq.__iter__(); for (PyObject item; (item = iter.__iternext__()) != null;) { // Do somting with item }
-
__setitem__
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 classPyObject
- Parameters:
key
- the key whose value will be set - must be an interned string .value
- the value to set this key to- See Also:
-
__setitem__
Description copied from class:PyObject
Equivalent to the standard Python __setitem__ method.- Overrides:
__setitem__
in classPyObject
- Parameters:
key
- the key whose value will be setvalue
- the value to set this key to
-
__delitem__
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 classPyObject
- Parameters:
key
- the key who will be removed - must be an interned string .- See Also:
-
__delitem__
Description copied from class:PyObject
Equivalent to the standard Python __delitem__ method.- Overrides:
__delitem__
in classPyObject
- Parameters:
key
- the key to be removed from the container
-
clear
public void clear()Remove all items from the dictionary. -
toString
-
__cmp__
Description copied from class:PyObject
Equivalent to the standard Python __cmp__ method. -
has_key
Return true if the key exist in the dictionary. -
get
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
Return this[key] if the key exists in the mapping, None is returned otherwise.- Parameters:
key
- the key to lookup in the mapping.
-
copy
Return a shallow copy of the dictionary. -
update
Insert all the key:value pairs frommap
into this mapping. -
update
Insert all the key:value pairs fromdict
into this mapping. -
setdefault
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
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
Return a random (key, value) tuple pair and remove the pair from the mapping. -
items
Return a copy of the mappings list of (key, value) tuple pairs. -
keys
Return a copy of the mappings list of keys. -
values
Return a copy of the mappings list of values. -
iteritems
return an iterator over (key, value) pairs -
iterkeys
return an iterator over the keys -
itervalues
return an iterator over the values
