reconfigure.items.bound

class reconfigure.items.bound.BoundCollection(node, item_class, selector=<function <lambda> at 0x251ee60>)

Binds a list-like object to a set of nodes

Parameters:

• node – target node (its children will be bound)
• item_class – BoundData class for items
• selector – lambda x: bool, used to filter out a subset of nodes

append(item)

insert(index, item)

pop(index)

rebuild()

Discards cached collection and rebuilds it from the nodes

remove(item)

to_dict()

to_json()

class reconfigure.items.bound.BoundData(node=None, **kwargs)

Binds itself to a node.

bind_* classmethods should be called on module-level, after subclass declaration.

Parameters:

• node – all bindings will be relative to this node
• kwargs – if node is None, template(**kwargs) will be used to create node tree fragment

classmethod bind(data_property, getter, setter)

Creates an arbitrary named property in the class with given getter and setter. Not usually used directly.

Parameters:

• data_property – property name
• getter – lambda: object, property getter
• setter – lambda value: None, property setter

classmethod bind_attribute(node_attribute, data_property, default=None, path=<function <lambda> at 0x26490c8>, getter=<function <lambda> at 0x2649140>, setter=<function <lambda> at 0x26491b8>)

Binds the value of node object’s attribute to a property

Parameters:

• node_attribute – Node‘s attribute name
• data_property – property name to be created
• default – default value of the property (is PropertyNode doesn’t exist)
• path – lambda self.node: PropertyNode, can be used to point binding to another Node instead of self.node.
• getter – lambda object: object, used to transform value when getting
• setter – lambda object: object, used to transform value when setting

classmethod bind_child(data_property, path=<function <lambda> at 0x2649578>, item_class=None)

Directly binds a child Node to a BoundData property

Parameters:

• data_property – property name to be created
• path – lambda self.node: PropertyNode, can be used to point binding to another Node instead of self.node.
• item_class – a BoundData subclass to be used for the property value

classmethod bind_collection(data_property, path=<function <lambda> at 0x26492a8>, selector=<function <lambda> at 0x2649320>, item_class=None, collection_class=<class 'reconfigure.items.bound.BoundCollection'>, **kwargs)

Binds the subset of node’s children to a collection property

Parameters:

• data_property – property name to be created
• path – lambda self.node: PropertyNode, can be used to point binding to another Node instead of self.node.
• selector – lambda Node: bool, can be used to filter out a subset of child nodes
• item_class – a BoundData subclass to be used for collection items
• collection_class – a BoundCollection subclass to be used for collection property itself

classmethod bind_name(data_property, getter=<function <lambda> at 0x2649410>, setter=<function <lambda> at 0x2649488>)

Binds the value of node’s name attribute to a property

Parameters:

• data_property – property name to be created
• getter – lambda object: object, used to transform value when getting
• setter – lambda object: object, used to transform value when setting

classmethod bind_property(node_property, data_property, default=None, default_remove=[], path=<function <lambda> at 0x2647e60>, getter=<function <lambda> at 0x2647ed8>, setter=<function <lambda> at 0x2647f50>)

Binds the value of a child reconfigure.node.PropertyNode to a property

Parameters:

• node_property – PropertyNode‘s name
• data_property – property name to be created
• default – default value of the property (is PropertyNode doesn’t exist)
• default_remove – if setting a value contained in default_remove, the target property is removed
• path – lambda self.node: PropertyNode, can be used to point binding to another Node instead of self.node.
• getter – lambda object: object, used to transform value when getting
• setter – lambda object: object, used to transform value when setting

template(**kwargs)

Override to create empty objects.

Returns:a reconfigure.nodes.Node tree that will be used as a template for new BoundData instance

class reconfigure.items.bound.BoundDictionary(key=None, **kwargs)

Binds a dict-like object to a set of nodes. Accepts same params as BoundCollection plus key

Parameters:key – lambda value: object, is used to get key for value in the collection

iteritems()

pop(key)
