示例1: nextToken

/**
 * Return the next token from the character stream and records this last
 * token in case it resides on the default channel. This recorded token
 * is used to determine when the lexer could possibly match a regex
 * literal.
 *
 * @return the next token from the character stream.
 */
@Override
public Token nextToken() {

    // Get the next token.
    Token next = super.nextToken();

    if (next.getChannel() == Token.DEFAULT_CHANNEL) {
        // Keep track of the last token on the default channel.
        this.lastToken = next;
    }

    return next;
