protected Token
consume()
Consume the current token.
Can only consume if accept was called before.
protected bool
accept(int $tokenType)
Accepts a token of a given type.
The Lexer will look up the regex for the token and try to match it on the current string. First match wins.
protected Token
expect(int $tokenType)
Expects a token of a given type.
The Lexer will look up the regex for the token and try to match it on the current string. First match wins.
protected bool
lazyExpect(int $tokenType)
Checks, if the token type matches the current, if so consume it and return true.
