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.
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 TokenSource.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.
Vocabulary	This interface provides information about the vocabulary used by a recognizer.
WritableToken

Class Summary

Class	Description
ANTLRFileStream	Deprecated. as of 4.7 Please use CharStreams interface.
ANTLRInputStream	Deprecated. as of 4.7 Please use CharStreams interface.
BailErrorStrategy	This implementation of ANTLRErrorStrategy responds to syntax errors by immediately canceling the parse operation with a ParseCancellationException.
BaseErrorListener	Provides an empty default implementation of ANTLRErrorListener.
BufferedTokenStream	This implementation of TokenStream loads tokens from a TokenSource on-demand, and places the tokens in a buffer to provide access to any previous token by index.
CharStreams	This class represents the primary interface for creating CharStreams from a variety of sources as of 4.7.
CodePointBuffer	Wrapper for ByteBuffer / CharBuffer / IntBuffer.
CodePointBuffer.Builder
CodePointCharStream	Alternative to ANTLRInputStream which treats the input as a series of Unicode code points, instead of a series of UTF-16 code units.
CommonToken
CommonTokenFactory	This default implementation of TokenFactory creates CommonToken objects.
CommonTokenStream	This class extends BufferedTokenStream with functionality to filter token streams to tokens on a particular channel (tokens where Token.getChannel() returns a particular value).
ConsoleErrorListener
DefaultErrorStrategy	This is the default implementation of ANTLRErrorStrategy used for error reporting and recovery in ANTLR parsers.
DiagnosticErrorListener	This implementation of ANTLRErrorListener can be used to identify certain potential correctness and performance problems in grammars.
InterpreterRuleContext	This class extends ParserRuleContext by allowing the value of InterpreterRuleContext.getRuleIndex() to be explicitly set for the context.
Lexer	A lexer is recognizer that draws input symbols from a character stream.
LexerInterpreter
ListTokenSource	Provides an implementation of TokenSource as a wrapper around a list of Token objects.
Parser	This is all the parsing support code essentially; most of it is error recovery stuff.
Parser.TrimToSizeListener
ParserInterpreter	A parser simulator that mimics what ANTLR's generated parser code does.
ParserRuleContext	A rule invocation record for parsing.
ProxyErrorListener	This implementation of ANTLRErrorListener dispatches all calls to a collection of delegate listeners.
Recognizer<Symbol,ATNInterpreter extends ATNSimulator>
RuleContext	A rule context is a record of a single rule invocation.
RuleContextWithAltNum	A handy class for use with options {contextSuperClass=org.antlr.v4.runtime.RuleContextWithAltNum;} that provides a backing field / impl for the outer alternative number matched for an internal parse tree node.
RuntimeMetaData	This class provides access to the current version of the ANTLR 4 runtime library as compile-time and runtime constants, along with methods for checking for matching version numbers and notifying listeners in the case where a version mismatch is detected.
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>
VocabularyImpl	This class provides a default implementation of the Vocabulary interface.

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.
