Returns true if OBJECT is an object (or sub-class) of Google::Checkout::General::Error. Returns false otherwise. Many functions reteurns Google::Checkout::General::Error to indicate error conditions so it's important to use this function to check for them.
Returns true if OBJECT is an object (or sub-class) of Google::Checkout::General::MerchantItem. Returns false otherwise. This function is used internally.
Returns true if OBJECT is an object (or sub-class) of Google::Checkout::General::Shipping. Returns false otherwise. This function is used internally.
Returns true if OBJECT is an object (or sub-class) of Google::Checkout::General::TaxTable. Returns false otherwise. This function is used internally.
Compute HMAC SHA1 for DATA. If B64 is true, also encode it in Base64 before returning.
Compute Base64 for DATA.
Given a valid date/time string, return it in ISO 8601 UTC format. If string is not a valid date/time string, Google::Checkout::General::Error is returned.
Make XML_DATE safe to be used in a XML document. '&' is turned into '&', '>' is turned into '>' and '<' is turned into '<'.
Make sure tax rate is in the right format. If RATE is less than 1, it's already in the right form so it's returned without any change. If RATE is equal to or greater than 1, it's assumed to be in percent format (for example, 25 means 25%) in which case it's turned into RATE / 100 (25 / 100 = 0.25).
Returns a valid carrier if CARRIER is valid. Returns Google::Checkout::General::Error otherwise. This function is used internally.
