Read-only properties

GraphvizTableCell.attributes

Gets Graphviz table cell attribute dictionary.

Returns dictionary.

(TreeNode).depth

The depth of a node in a rhythm-tree structure.

>>> a = datastructuretools.TreeContainer()
>>> b = datastructuretools.TreeContainer()
>>> c = datastructuretools.TreeNode()
>>> a.append(b)
>>> b.append(c)
>>> a.depth
0
>>> a[0].depth
1
>>> a[0][0].depth
2

Returns int.

(TreeNode).depthwise_inventory

A dictionary of all nodes in a rhythm-tree, organized by their depth relative the root node.

>>> a = datastructuretools.TreeContainer(name='a')
>>> b = datastructuretools.TreeContainer(name='b')
>>> c = datastructuretools.TreeContainer(name='c')
>>> d = datastructuretools.TreeContainer(name='d')
>>> e = datastructuretools.TreeContainer(name='e')
>>> f = datastructuretools.TreeContainer(name='f')
>>> g = datastructuretools.TreeContainer(name='g')
>>> a.extend([b, c])
>>> b.extend([d, e])
>>> c.extend([f, g])
>>> inventory = a.depthwise_inventory
>>> for depth in sorted(inventory):
...     print('DEPTH: {}'.format(depth))
...     for node in inventory[depth]:
...         print(node.name)
...

(TreeNode).graph_order

Graph order of tree node.

Returns tuple.

(TreeNode).improper_parentage

The improper parentage of a node in a rhythm-tree, being the sequence of node beginning with itself and ending with the root node of the tree.

>>> a = datastructuretools.TreeContainer()
>>> b = datastructuretools.TreeContainer()
>>> c = datastructuretools.TreeNode()
>>> a.append(b)

True
>>> c.parent is b
True

Returns tree node.

(TreeNode).proper_parentage

The proper parentage of a node in a rhythm-tree, being the sequence of node beginning with the node’s immediate parent and ending with the root node of the tree.

>>> a = datastructuretools.TreeContainer()
>>> b = datastructuretools.TreeContainer()
>>> c = datastructuretools.TreeNode()

>>> a = datastructuretools.TreeContainer()
>>> b = datastructuretools.TreeContainer()
>>> c = datastructuretools.TreeNode()
>>> a.append(b)
>>> b.append(c)
>>> a.root is a
True
>>> b.root is a
True

True

Returns tree node.

Read/write properties

(TreeNode).name

Named of tree node.

Returns string.

Special methods

(TreeNode).__copy__()

Copies tree node.

(AbjadObject).__eq__(expr)

Is true when ID of expr equals ID of Abjad object. Otherwise false.

Returns true or false.

(AbjadObject).__format__(format_specification='')

Formats Abjad object.

Set format_specification to ‘’ or ‘storage’. Interprets ‘’ equal to ‘storage’.

Returns string.

(AbjadObject).__hash__()

Hashes Abjad object.

Required to be explicitly redefined on Python 3 if __eq__ changes.

Returns integer.

(AbjadObject).__ne__(expr)

Is true when Abjad object does not equal expr. Otherwise false.

Returns true or false.

(AbjadObject).__repr__()

Gets interpreter representation of Abjad object.

Returns string.

GraphvizTableCell.__str__()

Get string representation of Graphviz table cell.

Returns string.
