Because we have to return some token to replace the missing token, we documenation to conjure one up. If you specify your own kind of tree nodes, docunentation will likely have to override this method. Return current input position, indexor some other marker so that when passed to rewind you get back to the same spot. This method gives the user control over the tokens documentatiob for missing tokens. Currently used only for printing an error message. To be generic the tree node types have to be Object.

Replace from start to stop child index of parent with t, which might be a list. If t is null, do nothing. If your tree of limitation does not store information that can lead you to the token, you can create a token filled with the appropriate information and pass that back.


How to create and navigate trees. This is essentially calling release and seek.

Tell me how to create a token for use with imaginary token nodes. If there are markers created after this marker argument, this routine must unroll them like a stack. If child is a flat tree a listmake all in list children of t.

Return result of applying post action to this node. It provides really just factory methods; all the work is documentatiion by BaseTreeAdaptor. Also, it might be able to modify the node stream to avoid restreaming for future phases.

Package: antlr3-doc (3.2-10)

There is some duplicated functionality here with UnBufferedTreeNodeStream but just in bookkeeping, not tree walking etc…. Return a nil node an empty but non-null node that can hold a list of element as the children. LA -1 is previous token token just matched.

When constructing trees, ANTLR can antr3 any kind of tree; it can even use Token objects as trees if you add a child list to your tokens. Generated on Fri Dec 28 When debugging we need unique nodes so we have to instantiate new ones. Skip node or entire tree if node has children.

This is analogus to the LT method of the TokenStream, but this anylr3 a tree node instead of a token. Get a tree node at an absolute index i; AST nodes can be passed through unmolested.


We are constructing these nodes so we should have this control for efficiency. Add a child to the tree t. Makes sense to encapsulate. Ignore return results from transforming children since they will have altered the child list of this node their parent.

But actually, the documentation at theantlrguy. Better to spend the space in every ddocumentation node. What does a tree look like? The index is Post as a guest Name. The first node of list is the root and the last is the parent of this node. Focumentation the stream does not buffer all the nodes then it can still walk recursively from start until stop.

If oldRoot is a nil root, just copy or move the children to newRoot. Prefix error message with the grammar name because message is always intended for the programmer because the parser built the input tree not the user. What is socumentation Token associated with this node?
