static HIDDEN: number

Property Value

Inherited From Lexer.HIDDEN

Set the char stream and reset the lexer

inputStream: CharStream

Property Value

Inherited From Lexer.inputStream

Set the ATN interpreter used by the recognizer for prediction.

static MORE: number

Property Value

Inherited From Lexer.MORE

If profiling during the parse/lex, this will return DecisionInfo records for each decision in recognizer in a ParseInfo object.

parseInfo: Promise<ParseInfo | undefined>

Property Value

Inherited From Recognizer.parseInfo

static SKIP: number

Property Value

Inherited From Lexer.SKIP

sourceName: string

Property Value

Inherited From Lexer.sourceName

Indicate that the recognizer has changed internal state that is consistent with the ATN state passed in. This way we always know where we are in the ATN as the parser goes along. The rule context objects form a stack that lets us see the stack of invoking rules. Combine this and we have complete ATN configuration information.

state: number

Property Value

Inherited From Recognizer.state

Set the complete text of this token; it wipes any previous changes to the text.

text: string

Property Value

Inherited From Lexer.text

Override if emitting multiple tokens.

token: Token | undefined

Property Value

Inherited From Lexer.token

tokenFactory: TokenFactory

Property Value

Inherited From Lexer.tokenFactory

type: number

Property Value

Inherited From Lexer.type

function action(_localctx: RuleContext, ruleIndex: number, actionIndex: number)

Parameters

function sempred(_localctx: RuleContext, ruleIndex: number, predIndex: number): boolean

Parameters

Returns

function addErrorListener(listener: ANTLRErrorListener<number>)

Parameters

Inherited From Recognizer.addErrorListener

By default does not support multiple emits per nextToken invocation for efficiency reasons. Subclass and override this method, nextToken, and getToken (to push tokens into a list and pull from that list rather than a single variable as this implementation does).

function emit(): Token

Returns

Inherited From Lexer.emit

The standard method called to automatically emit a token at the outermost lexical rule. The token object should point into the char buffer start..stop. If there is a text override in 'text', use that to set the token's text. Override this method to emit custom Token objects or provide a new factory.

function emit(token: Token): Token

Parameters

Returns

Inherited From Lexer.emit

function emitEOF(): Token

Returns

Inherited From Lexer.emitEOF

Return a list of all Token objects in input char stream. Forces load of all tokens. Does not include EOF token.

function getAllTokens(): Token[]

Returns

Inherited From Lexer.getAllTokens

function getCharErrorDisplay(c: number): string

Parameters

Returns

Inherited From Lexer.getCharErrorDisplay

function getErrorDisplay(s: string | number): string

Parameters

Returns

Inherited From Lexer.getErrorDisplay

What is the error header, normally line/character position information?

function getErrorHeader(e: RecognitionException): string

Parameters

Returns

Inherited From Recognizer.getErrorHeader

function getErrorListenerDispatch(): ANTLRErrorListener<number>

Returns

Inherited From Recognizer.getErrorListenerDispatch

function getErrorListeners(): Array<ANTLRErrorListener<number>>

Returns

Inherited From Recognizer.getErrorListeners

Get a map from rule names to rule indexes. Used for XPath and tree pattern compilation.

function getRuleIndexMap(): ReadonlyMap<string, number>

Returns

Inherited From Recognizer.getRuleIndexMap

function getTokenType(tokenName: string): number

Parameters

Returns

Inherited From Recognizer.getTokenType

Get a map from token names to token types. Used for XPath and tree pattern compilation.

function getTokenTypeMap(): ReadonlyMap<string, number>

Returns

Inherited From Recognizer.getTokenTypeMap

function mode(m: number)

Parameters

Inherited From Lexer.mode

function more()

Inherited From Lexer.more

Return a token from this source; i.e., match a token on the char stream.

function nextToken(): Token

Returns

Inherited From Lexer.nextToken

function notifyListeners(e: LexerNoViableAltException)

Parameters

Inherited From Lexer.notifyListeners

function popMode(): number

Returns

Inherited From Lexer.popMode

function precpred(localctx: RuleContext | undefined, precedence: number): boolean

Parameters

Returns

Inherited From Recognizer.precpred

function pushMode(m: number)

Parameters

Inherited From Lexer.pushMode

function recover(re: LexerNoViableAltException)

Parameters

Inherited From Lexer.recover

Lexers can normally match any char in it's vocabulary after matching a token, so do the easy thing and just kill a character and hope it all works out. You can instead use the rule invocation stack to do sophisticated error recovery if you are in a fragment rule.

function recover(re: RecognitionException)

Parameters

Inherited From Lexer.recover

function removeErrorListener(listener: ANTLRErrorListener<number>)

Parameters

Inherited From Recognizer.removeErrorListener

function removeErrorListeners()

Inherited From Recognizer.removeErrorListeners

function reset()

Inherited From Lexer.reset

function reset(resetInput: boolean)

Parameters

Inherited From Lexer.reset

Instruct the lexer to skip creating a token for current lexer rule and look for another token. nextToken() knows to keep looking when a lexer rule finishes with token set to SKIP_TOKEN. Recall that if token==undefined at end of any token rule, it creates one for you and emits it.

function skip()

Inherited From Lexer.skip
