ANTLR 4 Runtime (Optimized) 4.9.0 · org.antlr.v4.runtime

Interface Summary

Modifier and Type	Interface and Description
public interface	ANTLRErrorListener<Symbol> How to emit recognition errors.
public interface	ANTLRErrorStrategy The interface for defining strategies to deal with syntax errors encountered during a parse by ANTLR-generated parsers.
public interface	CharStream A source of characters for an ANTLR lexer.
public interface	IntStream A simple stream of symbols whose values are represented as integers.
public interface	ParserErrorListener How to emit recognition errors for parsers.
public interface	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.
public interface	TokenFactory The default mechanism for creating tokens.
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 An `IntStream` whose symbols are `Token` instances.
public interface	UnicodeCharStream
public interface	Vocabulary This interface provides information about the vocabulary used by a recognizer.
public interface	WritableToken

Modifier and Type	Annotation and Description
public @interface	RuleDependencies This annotation allows multiple `RuleDependency` annotations to be applied to a single element.
public @interface	RuleDependency Declares a dependency upon a grammar rule, along with a set of zero or more dependent rules.
public @interface	RuleVersion

Class Summary

Modifier and Type	Class and Description
public class	ANTLRFileStream Deprecated as of 4.7 Please use `CharStreams` interface. This is an `ANTLRInputStream` that is loaded from a file all at once when you construct the object.
public class	ANTLRInputStream Deprecated as of 4.7 Please use `CharStreams` interface. Vacuum all input from a `Reader`/`InputStream` and then treat it like a `char[]` buffer.
public class	BailErrorStrategy This implementation of `ANTLRErrorStrategy` responds to syntax errors by immediately canceling the parse operation with a `ParseCancellationException`.
public class	BaseErrorListener Provides an empty default implementation of `ANTLRErrorListener`.
public class	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.
public class	CodePointBuffer Wrapper for `ByteBuffer` / `CharBuffer` / `IntBuffer`.
public abstract class	CodePointCharStream Alternative to `ANTLRInputStream` which treats the input as a series of Unicode code points, instead of a series of UTF-16 code units.
public class	CommonToken
public class	CommonTokenFactory This default implementation of `TokenFactory` creates `CommonToken` objects.
public class	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).
public class	ConsoleErrorListener
public class	DefaultErrorStrategy This is the default implementation of `ANTLRErrorStrategy` used for error reporting and recovery in ANTLR parsers.
public class	DiagnosticErrorListener This implementation of `ANTLRErrorListener` can be used to identify certain potential correctness and performance problems in grammars.
public class	FailedPredicateException A semantic predicate failed during validation.
public class	InputMismatchException This signifies any kind of mismatched input exceptions such as when the current input does not match the expected token.
public class	InterpreterRuleContext This class extends `ParserRuleContext` by allowing the value of `getRuleIndex` to be explicitly set for the context.
public abstract class	Lexer A lexer is recognizer that draws input symbols from a character stream.
public class	LexerInterpreter
public class	LexerNoViableAltException
public class	ListTokenSource Provides an implementation of `TokenSource` as a wrapper around a list of `Token` objects.
public class	NoViableAltException Indicates that the parser could not decide which of two or more paths to take based upon the remaining input.
public abstract class	Parser This is all the parsing support code essentially; most of it is error recovery stuff.
public class	ParserInterpreter A parser simulator that mimics what ANTLR's generated parser code does.
public class	ParserRuleContext A rule invocation record for parsing.
public class	ProxyErrorListener<Symbol> This implementation of `ANTLRErrorListener` dispatches all calls to a collection of delegate listeners.
public class	ProxyParserErrorListener
public class	RecognitionException The root of the ANTLR exception hierarchy.
public abstract class	Recognizer<Symbol, ATNInterpreter extends ATNSimulator>
public class	RuleContext A rule context is a record of a single rule invocation.
public class	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.
public class	TokenStreamRewriter Useful for rewriting out a buffered input token stream after doing some augmentation or other manipulations on it.
public class	UnbufferedCharStream Do not buffer up the entire char stream.
public class	UnbufferedTokenStream
public class	VocabularyImpl This class provides a default implementation of the `Vocabulary` interface.

Modifier and Type	Enum and Description
public enum	CharStreams This class represents the primary interface for creating `CharStream`s from a variety of sources as of 4.7.
public enum	Dependents
