Detailed Description
warnings.warn( "Using create() is deprecated, use createWithPayload()", DeprecationWarning, stacklevel=2 )warnings.warn( "Using create() is deprecated, use createFromToken()", DeprecationWarning, stacklevel=2 ) warnings.warn( "Using create() is deprecated, use createFromToken()", DeprecationWarning, stacklevel=2 ) warnings.warn( "Using create() is deprecated, use createFromType()", DeprecationWarning, stacklevel=2 ) A generic tree implementation with no payload. You must subclass to actually have any user data. ANTLR v3 uses a list of children approach instead of the child-sibling approach in v2. A flat tree (a list) is an empty node whose children represent the list. An empty, but non-null node is called "nil".

| def antlr3.tree.BaseTree.__init__ | ( | self, | ||
node = None | ||||
| ) |
Create a new node from an existing node does nothing for BaseTree as there are no fields other than the children list, which cannot be copied as the children are not considered part of this node.
Reimplemented in antlr3.tree.CommonTree, and antlr3.treewizard.TreePattern.
| def antlr3.tree.BaseTree.getChild | ( | self, | ||
| i | ||||
| ) |
| def antlr3.tree.BaseTree.getChildren | ( | self | ) |
| def antlr3.tree.BaseTree.getFirstChildWithType | ( | self, | ||

| ) |
| def antlr3.tree.BaseTree.getChildCount | ( | self | ) |
| def antlr3.tree.BaseTree.addChild | ( | self, | ||
| childTree | ||||
| ) |
Add t as child of this node.
Warning: if t has no children, but child does and child isNil then this routine moves children to t via t.children = child.children; i.e., without copying the array.
Reimplemented from antlr3.tree.Tree.
| def antlr3.tree.BaseTree.addChildren | ( | self, | ||
| children | ||||
| ) |
| def antlr3.tree.BaseTree.setChild | ( | self, | ||
| i, | ||||
| t | ||||
| ) |
Set ith child (0.
.n-1) to t; t must be non-null and non-nil node
Reimplemented from antlr3.tree.Tree.
| def antlr3.tree.BaseTree.deleteChild | ( | self, | ||
| i | ||||
| ) |
| def antlr3.tree.BaseTree.replaceChildren | ( | self, | ||
| startChildIndex, | ||||
| stopChildIndex, | ||||
| newTree | ||||
| ) |
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 from antlr3.tree.Tree.
| def antlr3.tree.BaseTree.isNil | ( | self | ) |
Indicates the node is a nil node but may still have children, meaning the tree is a flat list.
Reimplemented from antlr3.tree.Tree.
Reimplemented in antlr3.tree.CommonTree, and antlr3.tree.CommonErrorNode.

Print out a whole tree not just a node.

In case we don't have a token payload, what is the line for errors?

Reimplemented in antlr3.tree.CommonTree.
| def antlr3.tree.BaseTree.getCharPositionInLine | ( | self | ) |
| def antlr3.tree.BaseTree.toString | ( | self | ) |
Override to say how a node (not a tree) should look as text.
Reimplemented from antlr3.tree.Tree.
Reimplemented in antlr3.tree.CommonTree, antlr3.tree.CommonErrorNode, and antlr3.treewizard.TreePattern.
