pytype.test_data.pytree.Leaf

class documentation

class Leaf(Base): (source)

Concrete implementation for leaf nodes. The __str__ value is derived from the prefix and the value. The prefix is any white space and comments before this item (e.g., Leaf(token.NEWLINE, value=" ", prefix=" # comment"). The _eq method (see Base.__eq__) compares only type and value.

Method	`__init__`	Initializer.
Method	`__repr__`	Return a canonical string representation.
Method	`__unicode__`	Return a pretty string representation.
Method	`clone`	Return a cloned (deep) copy of self.
Method	`leaves`	Undocumented
Method	`post_order`	Post-order iterator for the tree.
Method	`pre_order`	Pre-order iterator for the tree.
Class Variable	`column`	Undocumented
Class Variable	`lineno`	Undocumented
Class Variable	`prefix`	Undocumented
Instance Variable	`fixers_applied`	Undocumented
Instance Variable	`type`	Undocumented
Instance Variable	`value`	Undocumented
Method	`_eq`	Compare two nodes for equality (type and value).
Method	`_prefix_getter`	The whitespace and comments preceding this token in the input.
Method	`_prefix_setter`	Undocumented
Instance Variable	`_prefix`	Undocumented

Inherited from Base:

Method	`__eq__`	Compare two nodes for equality.
Method	`__ne__`	Compare two nodes for inequality.
Method	`__new__`	Constructor that prevents Base from being instantiated.
Method	`__str__`	Undocumented
Method	`changed`	Undocumented
Method	`depth`	Undocumented
Method	`descend_to`	Takes a sequence of integers and descends via children.
Method	`get_lineno`	Return the line number which generated the invocant node.
Method	`get_prefix`	Return the prefix for the node (see Leaf class).
Method	`get_suffix`	Return the string immediately following the invocant node. This is effectively equivalent to node.next_sibling.prefix
Method	`label_nodes`	Create 'label' attritbute for each Node/Leaf.
Method	`remove`	Remove the node from the tree. Returns the position of the node in its parent's children before it was removed.
Method	`replace`	Replace this node with a new one in the parent.
Method	`set_prefix`	Set the prefix for the node (see Leaf class).
Class Variable	`__hash__`	Undocumented
Class Variable	`children`	Undocumented
Class Variable	`was_checked`	Undocumented
Instance Variable	`label`	Undocumented
Instance Variable	`parent`	Undocumented
Instance Variable	`was_changed`	Undocumented
Property	`next_sibling`	The node immediately following the invocant in their parent's children list. If the invocant does not have a next sibling, it is None
Property	`prev_sibling`	The node immediately preceding the invocant in their parent's children list. If the invocant does not have a previous sibling, it is None.
Property	`type_repr`	Get the type as a human-readable string.

def __init__(self, type, value, context=None, prefix=None, fixers_applied=[]): (source) ¶

Initializer. Takes a type constant (a token number < 256), a string value, and an optional context keyword argument (prefix, (lineno, column)). If the prefix keyword argument is provided, it overrides the prefix derived from the context. The prefix is the text that appears before the value (e.g., blanks and comments).

def __repr__(self): (source) ¶

Return a canonical string representation.

def __unicode__(self): (source) ¶

Return a pretty string representation. This reproduces the input source exactly.

def clone(self): (source) ¶

overrides pytype.test_data.pytree.Base.clone

Return a cloned (deep) copy of self.

def leaves(self): (source) ¶

overrides pytype.test_data.pytree.Base.leaves

def post_order(self): (source) ¶
