| Interface | Description |
|---|---|
| CharStream |
A source of characters for an ANTLR lexer
|
| IntStream |
A simple stream of integers used when all I care about is the char
or token type sequence (such as interpretation).
|
| Token | |
| 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.
|
| TokenStream |
A stream of tokens accessing tokens from a TokenSource
|
| Class | Description |
|---|---|
| ANTLRFileStream |
This is a char buffer stream that is loaded from a file
all at once when you construct the object.
|
| ANTLRInputStream |
A kind of ReaderStream that pulls from an InputStream.
|
| ANTLRReaderStream |
Vacuum all input from a Reader and then treat it like a StringStream.
|
| ANTLRStringStream |
A pretty quick CharStream that pulls all data from an array
directly.
|
| BaseRecognizer |
A generic recognizer that can handle recognizers generated from
lexer, parser, and tree grammars.
|
| BitSet |
A stripped-down version of org.eclipse.persistence.internal.libraries.antlr.misc.BitSet that is just
good enough to handle runtime requirements such as FOLLOW sets
for automatic error recovery.
|
| BufferedTokenStream |
Buffer all input tokens but do on-demand fetching of new tokens from
lexer.
|
| 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.
|
| ClassicToken |
A Token object like we'd use in ANTLR 2.x; has an actual string created
and associated with this object.
|
| CommonToken | |
| 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).
|
| DFA |
A DFA implemented as a set of transition tables.
|
| 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).
|
| Lexer |
A lexer is recognizer that draws input symbols from a character stream.
|
| Parser |
A parser for TokenStreams.
|
| ParserRuleReturnScope |
Rules that return more than a single value must return an object
containing all the values.
|
| RecognizerSharedState |
The set of fields needed by an abstract recognizer to recognize input
and recover from errors etc...
|
| RuleReturnScope |
Rules can return start/stop info as well as possible trees and templates
|
| SerializedGrammar | |
| TokenRewriteStream |
Useful for dumping out the input stream after doing some
augmentation or other manipulations.
|
| UnbufferedTokenStream |
A token stream that pulls tokens from the code source on-demand and
without tracking a complete buffer of the tokens.
|
| Exception | Description |
|---|---|
| EarlyExitException |
The recognizer did not match anything for a (..)+ loop.
|
| FailedPredicateException |
A semantic predicate failed during validation.
|
| MismatchedNotSetException | |
| MismatchedRangeException | |
| MismatchedSetException | |
| MismatchedTokenException |
A mismatched char or Token or tree node
|
| MismatchedTreeNodeException | |
| MissingTokenException |
We were expecting a token but it's not found.
|
| NoViableAltException | |
| RecognitionException |
The root of the ANTLR exception hierarchy.
|
| UnwantedTokenException |
An extra token while parsing a TokenStream
