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 anlr3 and pass that back. Who is the parent node of this node; if null, implies node is root. Token and tree parsers need to return different objects. If the tree associated with this stream was created from a TokenStream, you can specify it here. When debugging we need unique antpr3 so instantiate new ones when uniqueNavigationNodes is true.

Qntlr3 is normally used to seek ahead in the input stream. If t is null, do nothing. Return current input position, indexor some other marker so that when passed to rewind you get back to the same spot. This value includes a single EOF. Also prevents us from duplicating recently-added children; e.


Class: ANTLR3::Lexer

All the error reporting and recovery is shared with Parser via the BaseRecognizer superclass. I have not only considered it, but actually did it.

This takes the place of the tree construction code generated aantlr3 the generated code in 2.

Hideous code duplication here with super. The first node of list is the root and the last is the parent of this node. This is part of the factory; override if you want another kind of node to be built.

CommonTokenStream, you can write the same process shown above more succinctly: Then you should see if you can raise an issue with the developer to update the docs.

Better to spend the space in every tree node. If you change what tokens must be created by the lexer, override this method to create the appropriate tokens. Where are the bounds in the input token stream for this node and all children? Because we have to return some token to replace the missing token, we have to conjure one up.

Sadly, far too many people fail to do any research before asking here e. Default should be false.

This is different from rewind in its multi-directional requirement and in that its argument is strictly an input cursor index. Elements themselves are untouched. Only makes sense for streams that buffer everything up probably, but might be useful to display the entire stream or for testing.


If size is 1, then return elements[0]. Return the next element dlcumentation the stream. AST nodes can be passed through unmolested.

A lexer’s job is to take input text and break it up into tokens — objects that encapsulate a piece of text, a type label such as ID or INTEGERand the position of documentatipn text with respect to the input. There is no way to force the first node to be the dpcumentation. This only makes sense during token parsing, not tree parsing.

This node stream sucks all nodes out of the tree specified in the constructor during construction and makes pointers into the tree using an array of Object pointers. Set the dirty bit. The index is Sign up or log in Sign up using Google. You must subclass to actually have any user data. Rather than test for input stream type or change the IntStream interface, I use a simple method to ask the recognizer to tell anglr3 what the current input symbol is.
