For huge child lists, inserting children can force walking rest of children to set their childindex; could be slow. Antlrr3 stream emits trees; tokens must be converted to AST nodes. Because we have to return some token to replace the missing token, we have to conjure one up.

There is no way to force the first node to be the root. This needs to always call dup node and super.

The text will be the token. Normally, implementations will pass the buck all the way to the lexer who can ask its input stream for the file name or whatever. In anylr3 words, it is assumed that people dont RTFM: Assume the state the stream was in when this marker was created. This must throw away resources for all markers back to the marker argument.


Set the dirty bit. How to create and navigate trees. If oldRoot is a nil root, just copy or move the children to newRoot.

This is a tree node documentatiom any payload; just navigation and factory stuff. If the tree associated with this stream was created from a TokenStream, you can specify it here. Currently, this method is only used for efficient backtracking using memoization, but in the future it may be used for incremental parsing.

Hideous code duplication here with super. This is not the name, but the object that provides node objects.

What is the Token associated with this node? Reset the stream so that next call to index would return marker. Do nothing if t or child is null.

Return the next element in the stream. This will have the same behavior as rewind except it releases resources without the backward seek. It provides really just factory methods; all the work is done by BaseTreeAdaptor. Where are qntlr3 getting symbols documenation So, seeking to 0 means LA 1 will return the first element in the stream. Return current input position, indexor some other marker so that when passed to rewind you get back to the same spot.

All the error reporting and recovery is dochmentation with Parser via the BaseRecognizer superclass. This is the most common create call. Also prevents us from duplicating recently-added children; e.


Can anyone tell me what changed here from 3. The generated class will provide an implementation of each lexer rule as a method of the same name.

For char streams, seeking forward must update the stream state such as line number.

I have not only considered it, but actually did it. Reset the condition of this stream so that it appears we have not consumed any of its elements. You must specify the input stream so that the erroneous text can be packaged up in the error docunentation. ANTLR v3 uses a list of children approach instead of the child-sibling approach in v2. A seek to position i means that LA 1 will return the ith symbol.

If size is 1, then return elements[0]. Once we reset the stream, any future use will need duplicates. I do not need to know the type of a tree at all so they are all documentatoon Objects. Number of children may be different after this call.
