Method Details

[hide private]

init(self, *args, **kwargs)
(Constructor)

source code

constructor

**Arguments**

  - parent: the parent of this node in the tree

  - name: the name of the node

  - label: the node's label (should be an integer)

  - data: an optional data field

  - level: an integer indicating the level of this node in the hierarchy
    (used for printing)

  - isTerminal: flags a node as being terminal.  This is useful for those
    times when it's useful to know such things.

Overrides: Tree.TreeNode.__init__: (inherited documentation)

ClassifyExample(self, example, appendExamples=0)

source code

Recursively classify an example by running it through the tree

**Arguments**

  - example: the example to be classified

  - appendExamples: if this is nonzero then this node (and all children)
    will store the example

**Returns**

  the classification of _example_

**NOTE:**
  In the interest of speed, I don't use accessor functions
  here.  So if you subclass DecTreeNode for your own trees, you'll
  have to either include ClassifyExample or avoid changing the names
  of the instance variables this needs.

Overrides: DecTree.DecTreeNode.ClassifyExample

cmp(self, other)
(Comparison operator)

source code

allows tree1 == tree2

**Note**

  This works recursively

Overrides: Tree.TreeNode.__cmp__: (inherited documentation)

lt(self, other)
(Less-than operator)

source code

allows tree1 < tree2

**Note**

  This works recursively

Overrides: Tree.TreeNode.__lt__: (inherited documentation)

eq(self, other)
(Equality operator)

source code

Overrides: Tree.TreeNode.__eq__

str(self)
(Informal representation operator)

source code

returns a string representation of the tree

**Note**

  this works recursively

Overrides: Tree.TreeNode.__str__
