| Modifier and Type | Interface and Description |
|---|---|
| public interface | CharStream
A source of characters for an ANTLR lexer |
| public interface | IntStream
A simple stream of integers used when all I care about is the char or token type sequence (such as interpretation). |
| public interface | |
| public interface | TokenSource
A source of tokens must provide a sequence of tokens via nextToken() and also must reveal it's source of characters; CommonToken's text is computed from a CharStream; it only store indices into the char stream. |
| public interface | TokenStream
A stream of tokens accessing tokens from a TokenSource |
| Modifier and Type | Class and Description |
|---|---|
| public class | ANTLRFileStream
This is a char buffer stream that is loaded from a file all at once when you construct the object. |
| public class | ANTLRInputStream
A kind of ReaderStream that pulls from an InputStream. |
| public class | ANTLRReaderStream
Vacuum all input from a Reader and then treat it like a StringStream. |
| public class | ANTLRStringStream
A pretty quick CharStream that pulls all data from an array directly. |
| public abstract class | BaseRecognizer
A generic recognizer that can handle recognizers generated from lexer, parser, and tree grammars. |
| public class | BitSet
A stripped-down version of org.antlr.misc.BitSet that is just good enough to handle runtime requirements such as FOLLOW sets for automatic error recovery. |
| public class | BufferedTokenStream
Buffer all input tokens but do on-demand fetching of new tokens from lexer. |
| public class | CharStreamState
When walking ahead with cyclic DFA or for syntactic predicates, we need to record the state of the input stream (char index, line, etc...) so that we can rewind the state after scanning ahead. |
| public class | ClassicToken
A Token object like we'd use in ANTLR 2.x; has an actual string created and associated with this object. |
| public class | |
| public class | CommonTokenStream
The most common stream of tokens where every token is buffered up and tokens are filtered for a certain channel (the parser will only see these tokens). |
| public class | DFA
A DFA implemented as a set of transition tables. |
| public class | EarlyExitException
The recognizer did not match anything for a (..)+ loop. |
| public class | FailedPredicateException
A semantic predicate failed during validation. |
| public class | LegacyCommonTokenStream
The most common stream of tokens is one where every token is buffered up and tokens are prefiltered for a certain channel (the parser will only see these tokens and cannot change the filter channel number during the parse). |
| public abstract class | Lexer
A lexer is recognizer that draws input symbols from a character stream. |
| public class | |
| public class | |
| public class | |
| public class | MismatchedTokenException
A mismatched char or Token or tree node |
| public class | |
| public class | MissingTokenException
We were expecting a token but it's not found. |
| public class | |
| public class | Parser
A parser for TokenStreams. |
| public class | ParserRuleReturnScope
Rules that return more than a single value must return an object containing all the values. |
| public class | RecognitionException
The root of the ANTLR exception hierarchy. |
| public class | RecognizerSharedState
The set of fields needed by an abstract recognizer to recognize input and recover from errors etc... |
| public class | RuleReturnScope
Rules can return start/stop info as well as possible trees and templates |
| public class | |
| public class | TokenRewriteStream
Useful for dumping out the input stream after doing some augmentation or other manipulations. |
| public class | UnbufferedTokenStream
A token stream that pulls tokens from the code source on-demand and without tracking a complete buffer of the tokens. |
| public class | UnwantedTokenException
An extra token while parsing a TokenStream |
