setWordChars method

@override void setWordChars(int fromSymbol, int toSymbol, bool enable)

Establish characters in the given range as valid characters for part of a word after the first character.

Note that the tokenizer must determine which characters are valid as the beginning character of a word.

• fromSymbol First character index of the interval.
• toSymbol Last character index of the interval.
• enable true if this state should use characters in the given range.

Implementation

@override
void setWordChars(int fromSymbol, int toSymbol, bool enable) {
  _map.addInterval(fromSymbol, toSymbol, enable);
}
