Abstract Value Members

  1. abstract def apply(s: String, i: Int, firstPosition: SourcePosition): Option[PrimitiveTokenListElem]

    s

    the string to lex

    i

    the current character

    firstPosition

    the SourcePosition of the first character

    returns

    the lexed Token, if applicable lexer extensions are called at every position of the input and therefore must fail very quickly if they are not applicable Make sure to call StringSlice(s,i) instead of s.substring(i) for efficiency.

  2. abstract def trigger: Option[String]

    if given, only applies to tokens that start with trigger
