[docs]class AnyNode(NodeMixin): """ A generic tree node with any `kwargs`. Keyword Args: parent: Reference to parent node. children: Iterable with child nodes. *: Any other given attribute is just stored as object attribute. Other than :any:`Node` this class has no default identifier. It is up to the user to use other attributes for identification. The `parent` attribute refers the parent node: >>> from anytree import AnyNode, RenderTree >>> root = AnyNode(id="root") >>> s0 = AnyNode(id="sub0", parent=root) >>> s0b = AnyNode(id="sub0B", parent=s0, foo=4, bar=109) >>> s0a = AnyNode(id="sub0A", parent=s0) >>> s1 = AnyNode(id="sub1", parent=root) >>> s1a = AnyNode(id="sub1A", parent=s1) >>> s1b = AnyNode(id="sub1B", parent=s1, bar=8) >>> s1c = AnyNode(id="sub1C", parent=s1) >>> s1ca = AnyNode(id="sub1Ca", parent=s1c) >>> root AnyNode(id='root') >>> s0 AnyNode(id='sub0') >>> print(RenderTree(root)) AnyNode(id='root') ├── AnyNode(id='sub0') │ ├── AnyNode(bar=109, foo=4, id='sub0B') │ └── AnyNode(id='sub0A') └── AnyNode(id='sub1') ├── AnyNode(id='sub1A') ├── AnyNode(bar=8, id='sub1B') └── AnyNode(id='sub1C') └── AnyNode(id='sub1Ca') >>> print(RenderTree(root)) AnyNode(id='root') ├── AnyNode(id='sub0') │ ├── AnyNode(bar=109, foo=4, id='sub0B') │ └── AnyNode(id='sub0A') └── AnyNode(id='sub1') ├── AnyNode(id='sub1A') ├── AnyNode(bar=8, id='sub1B') └── AnyNode(id='sub1C') └── AnyNode(id='sub1Ca') Node attributes can be added, modified and deleted the pythonic way: >>> root.new = 'a new attribute' >>> s0b AnyNode(bar=109, foo=4, id='sub0B') >>> s0b.bar = 110 # modified >>> s0b AnyNode(bar=110, foo=4, id='sub0B') >>> del s1b.bar >>> print(RenderTree(root)) AnyNode(id='root', new='a new attribute') ├── AnyNode(id='sub0') │ ├── AnyNode(bar=110, foo=4, id='sub0B') │ └── AnyNode(id='sub0A') └── AnyNode(id='sub1') ├── AnyNode(id='sub1A') ├── AnyNode(id='sub1B') └── AnyNode(id='sub1C') └── AnyNode(id='sub1Ca') The same tree can be constructed by using the `children` attribute: >>> root = AnyNode(id="root", children=[ ... AnyNode(id="sub0", children=[ ... AnyNode(id="sub0B", foo=4, bar=109), ... AnyNode(id="sub0A"), ... ]), ... AnyNode(id="sub1", children=[ ... AnyNode(id="sub1A"), ... AnyNode(id="sub1B", bar=8), ...
