CELParser class - CELParser library

Constructors

CELParser(TokenStream input)

Properties

ATNWithBypassAlts → ATN: The ATN with bypass alternatives is expensive to create so we create it lazily.
no setterinherited
buildParseTree ↔ bool: Specifies whether or not the parser should construct a parse tree during the parsing process. The default value is true.
getter/setter pairinherited
bypassAltsAtnCache ↔ ATN?: This field maps from the serialized ATN string to the deserialized ATN with bypass alternatives.
getter/setter pairinherited
context ↔ ParserRuleContext?: The ParserRuleContext object for the currently executing rule. This is always non-null during the parsing process.
getter/setter pairinherited
currentToken → Token: Match needs to return the current input symbol, which gets put into the label for the associated token ref; e.g., x=ID.
no setterinherited
dfaStrings → List<String>: For debugging and other purposes.
no setterinherited
errorHandler ↔ ErrorStrategy: The error handling strategy for the parser. The default value is a new instance of DefaultErrorStrategy.
getter/setter pairinherited
errorListenerDispatch → ErrorListener: no setterinherited
errorListeners → List<ErrorListener>: no setterinherited
expectedTokens → IntervalSet: Computes the set of input symbols which could follow the current parser state and context, as given by {@link #getState} and {@link #getContext}, respectively.
no setterinherited
expectedTokensWithinCurrentRule → IntervalSet: no setterinherited
grammarFileName → String: For debugging and other purposes, might want the grammar name. Have ANTLR generate an implementation for this method.
no setter
hashCode → int: The hash code for this object.
no setterinherited
inputStream ↔ TokenStream: covariantgetter/setter pairinherited
interpreter ↔ ParserATNSimulator?: The ATN interpreter used by the recognizer for prediction.
getter/setter pairinherited
matchedEOF ↔ bool: Indicates parser has match()ed EOF token. See {@link #exitRule()}. */
getter/setter pairinherited
numberOfSyntaxErrors → int: Gets the number of syntax errors reported during parsing. This value is incremented each time {@link #notifyErrorListeners} is called.
no setterinherited
parseInfo → ParseInfo?: If profiling during the parse/lex, this will return DecisionInfo records for each decision in recognizer in a ParseInfo object.
no setterinherited
parseListeners → List<ParseTreeListener>?: no setterinherited
precedence → int: Get the precedence level for the top-most precedence rule.
no setterinherited
ruleContext → ParserRuleContext: no setterinherited
ruleIndexMap → Map<String, int>: Get a map from rule names to rule indexes.
no setterinherited
ruleInvocationStack → List<String>: no setterinherited
ruleNames → List<String>: final
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
serializedATN → List<int>: If this recognizer was generated, it will have a serialized ATN representation of the grammar.
no setter
sourceName → String: no setterinherited
state ↔ int: getter/setter pairinherited
tokenFactory ↔ TokenFactory<Token>: Tell our token source and error strategy about a new way to create tokens.
getter/setter pairinherited
tokenStream → TokenStream: no setterinherited
tokenTypeMap → Map<String, int>: Get a map from token names to token types.
no setterinherited
trimParseTree ↔ bool: @return true if the {@link ParserRuleContext#children} list is trimmed using the default {@link Parser.TrimToSizeListener} during the parse process.
getter/setter pairinherited
vocabulary → Vocabulary: Get the vocabulary used by the recognizer.
no setter

Methods

action(RuleContext? _localctx, int ruleIndex, int actionIndex) → void: inherited
addContextToParseTree() → void: inherited
addErrorListener(ErrorListener listener) → void: inherited
addParseListener(ParseTreeListener listener) → void: Registers listener to receive events during the parsing process.
inherited
calc([int _p = 0]) → CalcContext
compileParseTreePattern(String pattern, int patternRuleIndex, [Lexer? lexer]) → ParseTreePattern: The preferred method of getting a tree pattern. For example, here's a sample use:
inherited
conditionalAnd() → ConditionalAndContext
conditionalOr() → ConditionalOrContext
consume() → Token: Consume and return the {@linkplain #getCurrentToken current symbol}.
inherited
createErrorNode(ParserRuleContext parent, Token t) → ErrorNode: How to create an error node, given a token, associated with a parent. Typically, the error node to create is not a function of the parent.
inherited
createTerminalNode(ParserRuleContext parent, Token t) → TerminalNode: How to create a token leaf node associated with a parent. Typically, the terminal node to create is not a function of the parent.
inherited
dumpDFA() → void: For debugging and other purposes. */
inherited
enterOuterAlt(ParserRuleContext localctx, int altNum) → void: inherited
enterRecursionRule(ParserRuleContext localctx, int state, int ruleIndex, int precedence) → void: inherited
enterRule(ParserRuleContext localctx, int state, int ruleIndex) → void: Always called by generated parsers upon entry to a rule. Access field {@link #_ctx} get the current context.
inherited
exitRule() → void: inherited
expr() → ExprContext
exprList() → ExprListContext
fieldInitializerList() → FieldInitializerListContext
getATN() → ATN: Get the ATN used by the recognizer for prediction.
getErrorHeader(RecognitionException<IntStream> e) → String: What is the error header, normally line/character position information? */
inherited
getInvokingContext(int ruleIndex) → ParserRuleContext?: inherited
getRuleIndex(String ruleName) → int: Get a rule's index (i.e., {@code RULE_ruleName} field) or -1 if not found. */
inherited
getRuleInvocationStack([RuleContext? p]) → List<String>: Return List<String> of the rule names in your parser instance leading up to a call to the current rule. You could override if you want more details such as the file/line info of where in the ATN a rule is invoked.
inherited
getTokenType(String tokenName) → int: inherited
inContext(String context) → bool: inherited
isExpectedToken(int symbol) → bool: Checks whether or not symbol can follow the current state in the ATN. The behavior of this method is equivalent to the following, but is implemented such that the complete context-sensitive follow set does not need to be explicitly constructed.
inherited
isMatchedEOF() → bool: inherited
isTrace() → bool: Gets whether a TraceListener is registered as a parse listener for the parser.
inherited
listInit() → ListInitContext
literal() → LiteralContext
mapInitializerList() → MapInitializerListContext
match(int ttype) → Token: Match current input symbol against ttype. If the symbol type matches, {@link ANTLRErrorStrategy#reportMatch} and {@link #consume} are called to complete the match process.
inherited
matchWildcard() → Token: Match current input symbol as a wildcard. If the symbol type matches (i.e. has a value greater than 0), {@link ANTLRErrorStrategy#reportMatch} and {@link #consume} are called to complete the match process.
inherited
member([int _p = 0]) → MemberContext
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyErrorListeners(String msg, [Token? offendingToken, RecognitionException<IntStream>? e]) → void: inherited
optExpr() → OptExprContext
optField() → OptFieldContext
precpred(RuleContext? localctx, int precedence) → bool: inherited
primary() → PrimaryContext
pushNewRecursionContext(ParserRuleContext localctx, int state, int? ruleIndex) → void: Like {@link #enterRule} but for recursive rules. Make the current context the child of the incoming localctx.
inherited
relation([int _p = 0]) → RelationContext
removeErrorListener(ErrorListener listener) → void: inherited
removeErrorListeners() → void: inherited
removeParseListener(ParseTreeListener? listener) → void: Remove listener from the list of parse listeners.
inherited
removeParseListeners() → void: Remove all parse listeners.
inherited
reset([bool resetInput = true]) → void: reset the parser's state */
inherited
sempred(RuleContext? _localctx, int ruleIndex, int predIndex) → bool
setProfile(bool profile) → void: @since 4.3
inherited
setTokenStream(TokenStream input) → void: Set the token stream and reset the parser. */
inherited
setTrace(bool trace) → void: During a parse is sometimes useful to listen in on the rule entry and exit events as well as token matches. This is for quick and dirty debugging.
inherited
start() → StartContext
toString() → String: A string representation of this object.
inherited
triggerEnterRuleEvent() → void: Notify any parse listeners of an enter rule event.
inherited
triggerExitRuleEvent() → void: Notify any parse listeners of an exit rule event.
