What does a tree look like? ANTLR has a number of support classes such as CommonTreeNodeStream that work on these kinds of trees. You don't have to make your trees implement this interface, but if you do, you'll be able to use more support code.
NOTE: When constructing trees, ANTLR can build any kind of tree; it can even use Token objects as trees if you add a child list to your tokens.
This is a tree node without any payload; just navigation and factory stuff.

def antlr3.tree.Tree.getParent | ( | self | ) |
Tree tracks parent and child index now > 3.0.
Reimplemented in antlr3.tree.BaseTree, and antlr3.tree.CommonTree.

def antlr3.tree.Tree.getAncestors | ( | self | ) |
Return a list of all ancestors of this node.
The first node of list is the root and the last is the parent of this node.

def antlr3.tree.Tree.getChildIndex | ( | self | ) |
This node is what child index? 0.

def antlr3.tree.Tree.freshenParentAndChildIndexes | ( | self | ) |
def antlr3.tree.Tree.addChild | ( | self, | ||
t | ||||
) |
Add t as a child to this node.
If t is null, do nothing. If t is nil, add all children of t to this' children.
Reimplemented in antlr3.tree.BaseTree.
def antlr3.tree.Tree.setChild | ( | self, | ||
i, | ||||
t | ||||
) |
Set ith child (0.
.n-1) to t; t must be non-null and non-nil node

i | ||||

def antlr3.tree.Tree.replaceChildren | ( | self, | ||
startChildIndex, | ||||
stopChildIndex, | ||||
t | ||||
) |
Delete children from start to stop and replace with t even if t is a list (nil-root tree).
num of children can increase or decrease. For huge child lists, inserting children can force walking rest of children to set their childindex; could be slow.
Reimplemented in antlr3.tree.BaseTree.
def antlr3.tree.Tree.isNil | ( | self | ) |
Indicates the node is a nil node but may still have children, meaning the tree is a flat list.
Reimplemented in antlr3.tree.BaseTree, antlr3.tree.CommonTree, and antlr3.tree.CommonErrorNode.
def antlr3.tree.Tree.getTokenStartIndex | ( | self | ) |
What is the smallest token index (indexing from 0) for this node and its children?
