How to use the ripple-address-codec.isValidClassicAddress function in ripple-address-codec

public getAddressDetails(address: string): Address {
    const destinationDetails = url.parse(address);
    const destinationAddress = destinationDetails.pathname;
    if (!destinationAddress || !rippleAddressCodec.isValidClassicAddress(destinationAddress)) {
      throw new InvalidAddressError(`destination address "${destinationAddress}" is not valid`);
    }
    // there are no other properties like destination tags
    if (destinationDetails.pathname === address) {
      return {
        address: address,
        destinationTag: undefined,
      };
    }

    if (!destinationDetails.query) {
      throw new InvalidAddressError('no query params present');
    }

    const queryDetails = querystring.parse(destinationDetails.query);
    if (!queryDetails.dt) {

function isValidAddress(address: string): boolean {
  return isValidXAddress(address) || isValidClassicAddress(address)
}
