Method Detail

__iter__

public PyObject __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:
 for (PyObject item : seq.asIterable()) {
     // Do somting with item
 }
 

Overrides:
__iter__ in class 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

__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

dictproxy___getitem__

public PyObject dictproxy___getitem__(PyObject key)

dictproxy___contains__

public boolean dictproxy___contains__(PyObject value)

dictproxy_has_key

public boolean dictproxy_has_key(PyObject key)

dictproxy_get

public PyObject dictproxy_get(PyObject key,
                              PyObject default_object)

dictproxy_keys

public PyObject dictproxy_keys()

dictproxy_values

public PyObject dictproxy_values()

dictproxy_items

public PyObject dictproxy_items()

dictproxy_iterkeys

public PyObject dictproxy_iterkeys()

dictproxy_itervalues

public PyObject dictproxy_itervalues()

dictproxy_iteritems

public PyObject dictproxy_iteritems()

dictproxy_copy

public PyObject dictproxy_copy()

__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 < o; 0 if this == o; +1 if this > o; -2 if no comparison is implemented

dictproxy___cmp__

public int dictproxy___cmp__(PyObject other)

dictproxy___lt__

public PyObject dictproxy___lt__(PyObject other)

dictproxy___le__

public PyObject dictproxy___le__(PyObject other)

dictproxy___eq__

public PyObject dictproxy___eq__(PyObject other)

dictproxy___ne__

public PyObject dictproxy___ne__(PyObject other)

dictproxy___gt__

public PyObject dictproxy___gt__(PyObject other)

dictproxy___ge__

public PyObject dictproxy___ge__(PyObject other)

__str__

public PyString __str__()
Description copied from class: PyObject
Equivalent to the standard Python __str__ method. This method should not typically need to be overridden. The easiest way to configure the string representation of a PyObject is to override the standard Java toString method.

Overrides:
__str__ in class PyObject

isMappingType

public boolean isMappingType()
Overrides:
isMappingType in class PyObject

isSequenceType

public boolean isSequenceType()
Overrides:
isSequenceType in class PyObject
