Trait Implementations

impl<T: LexerRecog<Recog = Self> + 'static> Lexer for BaseLexer<T>

fn set_channel(&mut self, v: isize)

Sets channel where current token will be pushed

fn push_mode(&mut self, _m: usize)

Pushes current mode to internal mode stack and sets m as current lexer mode `pop_mode should be used to recover previous mode

fn pop_mode(&mut self) -> Option<usize>

Pops mode from internal mode stack

fn set_type(&mut self, t: isize)

Sets type of the current token Called from action to override token that will be emitted by lexer

fn set_mode(&mut self, m: usize)

Sets lexer mode discarding current one

fn more(&mut self)

Used to informs lexer that it should consider next token as a continution of the current one

fn skip(&mut self)

Tells lexer to completely ignore and not emit current token.

fn reset(&mut self)

fn get_interpreter(&self) -> Option<&LexerATNSimulator>

impl<T: LexerRecog<Recog = Self> + 'static> Recognizer for BaseLexer<T>

fn action(
    &mut self,
    _localctx: &dyn ParserRuleContext,
    rule_index: isize,
    action_index: isize
)

fn get_rule_names(&self) -> &[&str]

Returns array of rule names. Used for debugging and error reporting

fn get_vocabulary(&self) -> &dyn Vocabulary

fn get_grammar_file_name(&self) -> &str

Name of the file this recognizer was generated from
