Interface Summary

Interface	Description
ANTLRErrorListener	How to emit recognition errors
ANTLRErrorStrategy	The interface for defining strategies to deal with syntax errors encountered during a parse by ANTLR-generated parsers and tree parsers.
CharStream	A source of characters for an ANTLR lexer.
IntStream	A simple stream of symbols whose values are represented as integers.
Token	A token has properties: text, type, line, character position in the line (so we can ignore tabs), token channel, index, and source from which we obtained this token.
TokenFactory<Symbol extends Token>	The default mechanism for creating tokens.
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	An IntStream whose symbols are Token instances.
WritableToken

Class Summary

Class	Description
ANTLRFileStream	This is an ANTLRInputStream that is loaded from a file all at once when you construct the object.
ANTLRInputStream	Vacuum all input from a Reader/InputStream and then treat it like a char[] buffer.
BailErrorStrategy	Bail out of parser at first syntax error.
BaseErrorListener
BufferedTokenStream	Buffer all input tokens but do on-demand fetching of new tokens from lexer.
CommonToken
CommonTokenFactory
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).
ConsoleErrorListener
DefaultErrorStrategy	This is the default error handling mechanism for ANTLR parsers and tree parsers.
DiagnosticErrorListener
Lexer	A lexer is recognizer that draws input symbols from a character stream.
Parser	This is all the parsing support code essentially; most of it is error recovery stuff.
Parser.TrimToSizeListener
ParserRuleContext	A rule invocation record for parsing.
ProxyErrorListener
Recognizer<Symbol,ATNInterpreter extends ATNSimulator>
RuleContext	A rule context is a record of a single rule invocation.
TokenStreamRewriter	Useful for rewriting out a buffered input token stream after doing some augmentation or other manipulations on it.
UnbufferedCharStream	Do not buffer up the entire char stream.
UnbufferedTokenStream<T extends Token>

Exception Summary

Exception	Description
FailedPredicateException	A semantic predicate failed during validation.
InputMismatchException	This signifies any kind of mismatched input exceptions such as when the current input does not match the expected token.
LexerNoViableAltException
NoViableAltException	Indicates that the parser could not decide which of two or more paths to take based upon the remaining input.
RecognitionException	The root of the ANTLR exception hierarchy.
