CommonTree Class |
A tree node that is wrapper for a Token object. After 3.0 release
while building tree rewrite stuff, it became clear that computing
parent and child index is very difficult and cumbersome. Better to
spend the space in every tree node. If you don't want these extra
fields, it's easy to cut them out in your own BaseTree subclass.

SyntaxThe CommonTree type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | CommonTree | Initializes a new instance of the CommonTree class |
| CommonTree(CommonTree) | Initializes a new instance of the CommonTree class |
| CommonTree(IToken) | Initializes a new instance of the CommonTree class |
Properties| Name | Description | |
|---|---|---|
 | CharPositionInLine | (Overrides BaseTreeCharPositionInLine.) |
| ChildCount | (Inherited from BaseTree.) |
| ChildIndex | (Overrides BaseTreeChildIndex.) |
| Children |
Get the children internal List; note that if you directly mess with
the list, do so at your own risk.
(Inherited from BaseTree.) |
| IsNil | (Overrides BaseTreeIsNil.) |
| Line | (Overrides BaseTreeLine.) |
| Parent | (Overrides BaseTreeParent.) |
| Text | (Overrides BaseTreeText.) |
| Token | |
| TokenStartIndex | (Overrides BaseTreeTokenStartIndex.) |
| TokenStopIndex | (Overrides BaseTreeTokenStopIndex.) |
| Type | (Overrides BaseTreeType.) |
Methods| Name | Description | |
|---|---|---|
| AddChild | Add t as child of this node. (Inherited from BaseTree.) |
| AddChildren | Add all elements of kids list as children of this node (Inherited from BaseTree.) |
 | CreateChildrenList | Override in a subclass to change the impl of children list (Inherited from BaseTree.) |
| DeleteChild | (Inherited from BaseTree.) |
| DupNode | (Overrides BaseTreeDupNode.) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| FreshenParentAndChildIndexes | Set the parent and child index values for all child of t (Inherited from BaseTree.) |
| FreshenParentAndChildIndexes(Int32) | (Inherited from BaseTree.) |
| FreshenParentAndChildIndexesDeeply | (Inherited from BaseTree.) |
| FreshenParentAndChildIndexesDeeply(Int32) | (Inherited from BaseTree.) |
| GetAncestor | Walk upwards and get first ancestor with this token type. (Inherited from BaseTree.) |
| GetAncestors |
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.
(Inherited from BaseTree.) |
| GetChild | (Inherited from BaseTree.) |
| GetFirstChildWithType | (Inherited from BaseTree.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| HasAncestor | Walk upwards looking for ancestor with this token type. (Inherited from BaseTree.) |
| InsertChild | (Inherited from BaseTree.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReplaceChildren |
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.
(Inherited from BaseTree.) |
| SanityCheckParentAndChildIndexes | (Inherited from BaseTree.) |
| SanityCheckParentAndChildIndexes(ITree, Int32) | (Inherited from BaseTree.) |
| SetChild | (Inherited from BaseTree.) |
| SetUnknownTokenBoundaries |
For every node in this subtree, make sure it's start/stop token's
are set. Walk depth first, visit bottom up. Only updates nodes
with at least one token index < 0.
|
| ToString | (Overrides BaseTreeToString.) |
| ToStringTree | Print out a whole tree not just a node (Inherited from BaseTree.) |
Fields| Name | Description | |
|---|---|---|
 | startIndex |
What token indexes bracket all tokens associated with this node
and below?
|
| stopIndex |
